Recombinant Rat Il9 Protein, C-His-tagged
Product Description
Cat
IMP-4770
Official Symbol
Il9
Product Overview
Recombinant rat IL9R / Interleukin 9 receptor (EDM04022.1) extracellular domain (Met 1-Ala 270) was expressed, fused with a polyhistidine tag at the C-terminus.
Description
IL9R (Interleukin 9 Receptor) is a Protein Coding gene. The protein encoded by this gene is a cytokine receptor that specifically mediates the biological effects of interleukin 9 (IL9). IL9 is involved in mast cell maturation and the enhancement of IgE production by B cells. Furthermore, linkage data in the human and mice have suggested that IL9 may contribute to asthma. The ligand binding of this receptor leads to the activation of various JAK kinases and STAT proteins, which connect to different biologic responses. IL9R is known to be autosomal in mice and is X-linked only in primates. The more recent X linkage and more telomeric position of the IL9R gene may explain its autosomal, 'un-inactivated' transcriptional status.

Form
Lyophilized from sterile PBS, pH 7.4, 5 % trehalose, 5% mannitol and 0.01% Tween80.
Molecular Mass
The recombinant rat IL9R / Interleukin 9 receptor comprises 244 amino acids and predicts a molecular mass of 28.2 kDa. The apparent molecular mass of the rat IL9R / Interleukin 9 receptor is approximately 36 kDa in SDS-PAGE under reducing conditions due to glycosylation.
Protein length
Met1-Ala270
Endotoxin
< 1.0 EU/μg of the protein as determined by the LAL method
Purity
> 90 % as determined by SDS-PAGE
Storage
Samples are stable for up to twelve months from date of receipt at -20 to -80 centigrade.
Store it under sterile conditions at -20 to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
Reconstitution
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
SDS-PAGE
SDS-PAGE

Bioactivity-Cell based assay 1
Bioactivity-Cell based assay

Measured by its ability to inhibit IL-9 dependent proliferation of MC/9 mouse mast cells. Approximately 0.03-0.15 μg/mL of IL-9R will inhibit 50% of the biological response induced by 50 ng/mL of recombinant ratIL-9.
