    • 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

      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.

    • Synonyms

      Serotransferrin, Transferrin, Siderophilin, Beta-1-metal-binding globulin, TF, PRO1557, PRO2086, DKFZp781D0156, Holo Transferrin, HTF.

    • Physical Appearance

    • Solubility

      It is recommended to reconstitute the lyophilized Bovine HTF in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

    • Human Virus Test

      FDA approved Plasma from each donor has been tested and found negative for antibody to HIV-1, HIV-2, HCV, HBSAG, HBc, ALT and Syphilis.Viral inactivation by pasteurization (60°C for 10 hours) has been validated using three different test viruses, with removal of 8-14.5 logs of virus documented. The purification process has also been found to remove significant additional quantities of virus.

    • Applications

      Bovine Transferrin is a crucial component for the cultivation of mammalian cells in-vitro. Bovine Transferrin is Critical for long-term cells growth in-vitro. Bovine Transferrin is used as detoxificant in media by binding contaminating metal ions. Bovine Transferrin is often used as a nutrient in fermentation media for recombinant protein and biopharmaceutical production. Additional common uses of Bovine Transferrin areMolecular weight, Affinity purification of anti-human transferrin antibodies and also as receptor mediated transfection of molecules such as DNA, into cells.

    • 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.

    • 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.

    • Introduction

      Streptavidin is a tetrameric protein secreted by Streptomyces avidinii which binds firmly to biotin. Streptavidin is widely used in molecular biology through its unique high affinity for the vitamin biotin. The dissociation constant (Kd) of the biotin-streptavidin complex is about ~10-15 mol/L. The strong affinity recognition of biotin and biotinylated molecules has made streptavidin one of the most important components in diagnostics and laboratory kits. The streptavidin/biotin system has one of the biggest free energies of association of yet observed for noncovalent binding of a protein and small ligand in aqueous solution (K_assoc = 10**14). The complexes are also extremely stable over a wide range of temperature and pH.
