Introduction
Osteoprotegerin acts as decoy receptor for rankl and thereby neutralizes its function in osteoclastogenesis. OPG inhibits the activation of osteoclasts and promotes osteoclast apoptosis in vitro. Bone homeostasis seems to depend on the local rankl/opg ratio. Osteoprotegerin may also play a role in preventing arterial calcification. May act as decoy receptor for trail and protect against apoptosis. Trail binding blocks the inhibition of osteoclastogenesis.

More Info

Introduction
Transferrin is the iron-transport protein of vertebrate serum and donates iron to cells through interaction with a specific membrane receptor, CD71. Transferrin appears to be indispensable for most cells growing in tissue culture.
It is referred to frequently as a growth factor because, in analogy to other growth factor-receptor interactions, proliferating cells express high numbers of transferrin receptors, and the binding of transferrin to their receptors is needed for cells to initiate and maintain their DNA synthesis. Apart from its role as an iron transport protein transferrin acts as a cytokine and has functions that may not be related to its iron-carrying capacity.

More Info

Introduction
The protein encoded by this gene is a member of the bone morphogenetic protein family which is part of the transforming growth factor-beta superfamily. The superfamily includes large families of growth and differentiation factors. Bone morphogenetic proteins were originally identified by an ability of demineralized bone extract to induce endochondral osteogenesis in vivo in an extraskeletal site. This particular family member plays an important role in the onset of endochondral bone formation in humans, and a reduction in expression has been associated with a variety of bone diseases, including the heritable disorder Fibrodysplasia Ossificans Progressiva. Alternative splicing in the 5' untranslated region of this gene has been described and three variants are described, all encoding an identical protein.

More Info

Introduction
Lactoferrin is a glycoprotein that belongs to the transferrin family of iron binding proteins. It is found in human breast milk as well as most epithelial surface secretions including tears, nasogastric, saliva, and bronchial. Lactoferrin binds 2 molecules of iron with very high affinity. Lactoferrin inhibits bacterial growth by withholding iron, its N-terminal region is an antimicrobial peptide. Lactotransferrin acts synergistically with lysozyme to potentiate the activity of both proteins. The multifunctional protein lactoferrin has many physiological possible roles.

Background
The FCER1A gene encodes the alpha subunit of the high-affinity immunoglobulin E (IgE) receptor, known as FCER1A. This receptor is primarily expressed on mast cells and basophils, and its activation plays a pivotal role in allergic and inflammatory responses. This research aims to explore the significance of FCER1A and its potential implications in allergic disorders and immune-mediated diseases. By investigating the functions and regulation of FCER1A, we can gain insights into its role in immune responses and identify potential therapeutic targets.
The FCER1A receptor is responsible for the binding of IgE antibodies, initiating a cascade of signaling events upon allergen exposure. Crosslinking of IgE-bound FCER1A leads to the release of various inflammatory mediators, such as histamine, cytokines, and leukotrienes, which contribute to the clinical manifestations of allergic reactions. Understanding the molecular mechanisms underlying FCER1A activation and downstream signaling is crucial for comprehending allergic diseases.
In addition to its role in allergies, FCER1A has been implicated in immune-mediated inflammatory diseases, including asthma, atopic dermatitis, and autoimmune conditions. Dysregulation of FCER1A expression and signaling pathways can lead to exaggerated immune responses and chronic inflammation. Investigating the genetic and epigenetic factors influencing FCER1A expression and the interplay between FCER1A and other immune molecules can provide valuable insights into disease pathogenesis.
This research will delve into the molecular mechanisms governing FCER1A expression, activation, and downstream signaling pathways. The paper will explore the regulatory effects of FCER1A on mast cell and basophil activation, the release of inflammatory mediators, and the recruitment of other immune cells. Additionally, it will examine the impact of FCER1A dysregulation in allergic and immune-mediated diseases and discuss the potential of FCER1A as a therapeutic target for intervention.
The study will also investigate the diagnostic and prognostic value of FCER1A in various allergic and immune disorders. Understanding the expression patterns and alterations of FCER1A in different diseases and patient populations may aid in disease stratification, treatment selection, and monitoring of treatment response.
By unraveling the molecular mechanisms underlying FCER1A's functions in allergic and inflammatory responses, this research aims to contribute to our understanding of immune-mediated diseases. Furthermore, it highlights the potential of FCER1A as a target for therapeutic interventions and emphasizes the need for further investigations to develop novel treatments and improve patient outcomes.

Purity

≥ 95.0% as determined by SDS-PAGE.

More Info

Introduction
Plasma fibronectin level is elevated in severe coronary artery disease. Increased plasma fibronectin levels are related with venous thromboembolism (VTE) particularly in males, and extend the probable association between biomarkers and risk factors for arterial atherothrombosis and VTE. Fibronectin plays a role in several cellular processes, including tissue repair, embryogenesis, blood clotting, and cell migration/adhesion. Fibronectin consists in two main forms: 1) as an insoluble glycoprotein dimer that serves as a linker in the extracellular matrix and 2) as a soluble disulphide linked dimer found in the plasma. The plasma form is produced by hepatocytes, and the ECM form is synthesized by fibroblasts, chondrocytes, endothelial cells, macrophages, as well as certain epithelial cells. Fibronectin also takes part as a general cell adhesion molecule by anchoring cells to collagen or proteoglycan substrates. Fibronectin organizes cellular interaction with the ECM by binding to different components of the extracellular matrix and to membrane-bound Fibronectin receptors on cell surfaces.
Physical Appearance
Filtered White lyophilized (freeze-dried) powder.
Stability
Lyophilized Fibronectin although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution Fibronectin should be stored at 4°C between 2-7 days and for future use below -18°C.
Solubility
We suggest reconstituting the 1mg Fibronectin with a chaotropic agent such as urea at room temperature at a concentration of 0.2mg/ml using sterile water. Let stand 1-2 hours. The recommended concentration is 4M-5M urea.
When using the protein as an attachment factor, wash the urea off after attaching the fibronectin to the growth surface (plate or dish).

Introduction
The OmpA protein is one of the main outer-membrane proteins of a large array of Gram-negative bacteria such as A.salmonicida, Shigella dysenteriae and E.coli.OmpA’s major physiological functions include maintenance of the structural integrity and morphology of the cells and porin activity, as well as a role in conjugation and bacteriophage binding.Achromogenic atypical Aeromonas salmonicida is the causative agent of goldfish ulcer disease.Virulence of this bacterium is associated with the production of a paracrystalline outer membrane A-layer protein.The species specific structural gene for the monomeric form of A-protein was cloned into a pET-3d plasmid in order to express and produce a recombinant form of the protein in E.coli BL21(DE3). The induced protein was isolated from inclusion bodies by a simple solubilization-renaturation procedure and purified by ion exchange chromatography on Q-Sepharose to over 95% pure monomeric protein.Recombinant A-protein was compared by biochemical, immunological and molecular methods with the A-protein isolated from atypical A.salmonicida bacterial cells by the glycine and the membrane extraction methods.

Introduction
Periostin is a disulfide linked 90 kDa, 811 amino acid protein originally isolated as a osteoblast-specific factor that functions as a cell adhesion molecule for preosteoblasts and is thought to be involved in osteoblast recruitment, attachment and spreading. Additionally, periostin expression has previously been shown to be significantly increased by both transforming growth factor beta-1(TGFbeta1) and bone morphogenetic protein (BMP-2). OSF-2 has a typical signal sequence, followed by a cysteine-rich domain, a fourfold repeated domain and a C-terminal domain. The fourfold repeated domain of OSF-2 shows homology with the insect protein fasciclin
Periostin mRNA is expressed in the developing mouse embryonic and fetal heart, and that it is localized to the endocardial cushions that ultimately divide the primitive heart tube into a four-chambered heart.

More Info

Introduction
Follistatin is a single-chain gonadal protein that specifically inhibits follicle-stimulating hormone release. The single FST gene encodes two isoforms, FST317 and FST344 containing 317 and 344 amino acids respectively, resulting from alternative splicing of the precursor mRNA. In a study in which 37 candidate genes were tested for linkage and association with polycystic ovary syndrome (PCOS) or hyperandrogenemia in 150 families, evidence was found for linkage between PCOS and follistatin. Follistatin binds directly to activin and functions as an activin antagonist. specific inhibitor of the biosynthesis and secretion of pituitary follicle stimulating hormone (fsh).
Synonyms
FST, FS, Activin-binding protein.
