Description

IL1RL1 produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 318 amino acids (19-328a.a.) and having a molecular mass of 36.0kDa. (Molecular size on SDS-PAGE will appear at approximately 40-57kDa).IL1RL1 is expressed with an 8 amino acid His tag at C-Terminus and purified by proprietary chromatographic techniques.

Source

Sf9, Baculovirus cells.

Formulation

IL1RL1 protein solution (0.5mg/ml) contains 10% glycerol & Phosphate Buffered Saline (pH 7.4).

Purity

Greater than 95.0% as determined by SDS-PAGE.

Biological Activity

Measured by its ability to inhibit proliferation using D10.G4.1 mouse helper T cells. The ED50 for this effect is less or equal to 10ng/ml with IL-33.

More Info

  • Introduction

    The IL1RL1 gene is a member of the IL-1 receptor family, encoding a transmembrane protein with a structure similar to IL-1R1. IL1RL1 is a receptor for interleukin-33, its stimulation recruits MYD88, IRAK1, IRAK4, and TRAF6, followed by phosphorylation of MAPK3/ERK1 and/or MAPK1/ERK2, MAPK14, and MAPK8. IL1RL1 may possibly be involved in helper T-cell function. IL1RL1 is highly expressed in kidney, lung, placenta, stomach, skeletal muscle, colon and small intestine.A soluble form of the IL1RL1 is produced from the same gene by alternative splicing and was shown to be expressed in several cell types including fibroblasts and mast cells. Soluble IL1RL1 also acts as a negative regulator of Th2 cytokine production and high levels have been reported in several disease states and conditions including asthma, sepsis and myocardial infarction.Analysis of the similar gene in mouse suggested that the IL1RL1 receptor can be induced by proinflammatory stimuli, and may be involved in the function of helper T cells.

Frequently asked questions

1. Which company offers Recombinant cytokines at competitive prices?

ProSpec offers vast array of cytokines such as Interferon-alpha | Interleukin-2 | TNF-alpha | BMP-2 and much more at affordable descent prices to meet academic budgets.
ProSpec provides High Purity cytokines for 30 years, purity exhibits 95% or more by SDS-PAGE gel.
Cytokines are in stock for immediate delivery via FedEx which enables scientists and researchers to perform immediate experiments.
Cytokines are shipped globally using ProSpec’s custom tailored Styrofoam insulated box and premium ice packs that ensure maximum protein stability during transit to your laboratory.

2. Where can i find biologically active cytokines?

ProSpec offers biologically functional cytokines such as Adiponectin | Cardiotrophin | Beta Defensin which are rigorously tested in-vitro to provide researchers world wide BioActive Cytokines.

3. What is the activity validation method for Cytokines?

ProSpec uses cell-based bioassays that measures the biological activity, for example:
Adiponectin is validated using AMPK phosphorylation assay, glucose uptake assay.
Angiopoietin is validated using Endothelial tube formation assay, Tie2 phosphorylation assay.
Apolipoprotein is validated using Lipid-binding assay, receptor-binding assay.
Beta Defensin is validated using Antimicrobial assay.
Betacellulin is validated using Cell proliferation assay (EGFR-positive cells).
Bone Morphogenetic Protein is validated using Alkaline phosphatase induction assay.

4. Is the cytokine full length or partial?

The cytokine proteins are both full length and partial while majority of them are active mature proteins rather than a full-length precursor. ProSpec active mature proteins exhibits higher expression yields, better stability, Easier purification and Equivalent biological activity as full length precursor.

5. Is the cytokine monomeric or dimeric form?

This depends on the cytokine. ProSpec cytokines are supplied in the native biologically active oligomeric state, which can be monomeric, dimeric, trimeric, or even multimeric since because receptor binding and biological activity often depend on correct oligomerization.
The interleukin and interferon protein family are usually provided as monomer proteins though adiponectin and TNFSF8 are supplied as homodimers.

6. What is the cytokine purity and how was it determined?

The cytokine purity ranges from high purity of ≥95% to premium grade ≥97%.
ProSpec uses SDS-PAGE Coomassie Blue Staining as the primary purity method which Visualizes protein bands. Some SDS-PAGE gels are stained with Silver Stain. Other analytical methods include RP-HPLC [ High-resolution purity determination ] , SEC-HPLC for the detections of aggregates and fragments and Western Blot to confirm cytokine identity.

7. Is the cytokine sequence verified?

The amino acid sequence verification is performed at DNA & protein level.
Sanger DNA Sequencing verifies the expression plasmid having correct coding.
LC-MS is used to verify the molecular weight of the final purified cytokine
Prospec also uses Edman N-terminal Sequencing to determine the amino-terminal sequence.

8. What is the endotoxin level in cytokines and how do you test LPS ?

ProSpec cytokines are tested for endotoxin also named LPS [ lipopolysaccharide ] which is found in the outer membrane of Gram-negative bacteria which can affect cytokine secretion, cell proliferation and stem cell.
ProSpec measures endotoxin using the Limulus Amebocyte Lysate [ LAL ] assay such as Gel-Clot.
ProSpec standard Endotoxin level for cytokines is usually <1 EU/ug.
What Does "EU" Mean? EU = Endotoxin Units

9. Is there host cell protein contamination?

There might be a minor existence of host-cell proteins post chromatography purification and quality-control procedures that greatly minimize these impurities. ProSpec tests host-cell protein levels by SDS-PAGE silver staining, or mass spectrometry.

10. Is the protein tested in vitro, in-vivo cell culture, stem cells, T cells, ELISA, western blot?

PoSpec Growth Factors proteins are usually tested for biological activity and identity, while some proteins are not though supported by literature and customer experience. Interleukins are tested in T-cell, NK-cell, PBMC, stem cell culture. Interferons are tested in Antiviral assays, immune-cell activation, TNFA proteins are tested in Apoptosis, inflammation and immune studies. ProSpec does not conduct in-vivo or animal injections experiments in house or our source.
