Name : Biotinylated Human TIGIT Protein
Product Source :
Recombinant Biotinylated Human TIGIT Protein is expressed from HEK293 with His tag and Avi tag at the C-Terminus. It contains Met22-Pro141.[Accession | Q495A1]
Molecular Weight :
The protein has a predicted MW of 16.1 kDa. Due to glycosylation, the protein migrates to 20-25 kDa based on Tris-Bis PAGE result.
Endotoxin Level :
Less than 1EU per μg by the LAL method.
Purity :
> 95% as determined by Tris-Bis PAGE> 95% as determined by HPLC
Formulation :
Lyophilized from 0.22μm filtered solution in PBS (pH 7.4). Normally 8% trehalose is added as protectant before lyophilization.
Reconstitution :
Centrifuge the tube before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage and Stability :
-20 to -80°C for 12 months as supplied from date of receipt. -80°C for 3-6 months after reconstitution. 2-8°C for 2-7 days after reconstitution. Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
Product Concentration :
Tris-Bis PAGE Biotinylated Human TIGIT on Tris-Bis PAGE under reduced condition. The purity is greater than 95%. SEC-HPLC The purity of Biotinylated Human TIGIT is greater than 95% as determined by SEC-HPLC. ELISA Data Immobilized Biotinylated Human TIGIT, His-Avi Tag at 0.5μg/ml (100μl/well) on the streptavidin precoated plate (5μg/ml). Dose response curve for Human CD155, hFc Tag with the EC50 of 11.7ng/ml determined by ELISA.
Background :
TIGIT, also called Vstm3, Vsig9, and WUCAM, is a transmembrane protein in the CD28 family of the Ig superfamily proteins.TIGIT is expressed at low levels on peripheral memory and regulatory CD4 T-cells and NK cells and is up-regulated following activation of these cells.
Synonyms :
TIGIT; VSIG9; VSTM3; WUCAM
