Recombinant Biotinylated Human IL-17 RA / CD217 Protein, Fc Tag, Avi Tag (Avitag™), 25 µg

Background
Interleukin 17 receptor A (IL17RA) is also known as cluster of differentiation w217 (CDw217), is a pro-inflammatory cytokine secreted by activated T-lymphocytes, belong to ubiquitous type I membrane glycoprotein, and binds with low affinity to interleukin 17A (IL17A). IL 17R mRNA exhibits a broad tissue distribution, and has been detected in virtually all cells and tissues tested . IL 17RA associates with IL 17RC to form a signaling receptor complex for IL 17 and IL 17F . Ligand and IL 17RA ligation promotes T cell activation and the production of IL - 6, G-CSF, SCF, and multiple pro-inflammatory chemokines. Defects in IL17RA are the cause of familial candidiasis type 5 (CANDF5).

Source
Recombinant Biotinylated Human IL-17 RA, Fc,Avitag (ILA-H82F1) is expressed from human 293 cells (HEK293). It contains AA Leu 33 - Trp 320 (Accession # Q96F46-1).
Predicted N-terminus: Leu 33

Molecular Characterization
This protein carries a human IgG1 Fc tag at the C-terminus, followed by an Avi tag (Avitag™)
The protein has a calculated MW of 61.9 kDa. The protein migrates as 80-115 kDa under reducing (R) condition, and 150-200 kDa under non-reducing (NR) condition (SDS-PAGE) due to glycosylation.

Biotinylation
Biotinylation of this product is performed using Avitag™ technology. Briefly, the single lysine residue in the Avitag is enzymatically labeled with biotin.
Biotin:Protein Ratio
Passed as determined by the HABA assay / binding ELISA.

Endotoxin
Less than 1.0 EU per μg by the LAL method.

Purity
>95% as determined by SDS-PAGE.

Formulation
Lyophilized from 0.22 μm filtered solution in Tris with Glycine, Arginine and NaCl, pH7.5 with trehalose as protectant.

Reconstitution
Please see Certificate of Analysis for specific instructions.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.

Storage
