|Product Overview :||Recombinant Rhesus BTLA Protein (EHH16054.1) (Met1-Leu155) was produced by HEK293 Cells expression system. This protein was expressed with a polyhistidine tag at the C-terminus.|
|Description :||BTLA is a inhibitory molecule which belongs to the Ig superfamily. It down-modulates immune responses. As such, reagents that regulate the binding of BTLA to its ligand or alter BTLA signaling have significant therapeutic promise. BTLA is crucial to understand the mechanism(s) of action of these antibodies before attempting clinical applications. BTLA is not expressed by naive T cells, but it is induced during activation and remains expressed on T helper type 1 (T(H)1) but not T(H)2 cells. BTLA is a third inhibitory receptor on T lymphocytes with similarities to cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) and programmed death 1 (PD-1).|
|Predicted N Terminal :||Met 1|
|Form :||Lyophilized from sterile PBS, pH 7.4. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.|
|Molecular Mass :||The recombinant BTLA consists of 166 amino acids and predicts a molecular mass of 19.3 kDa.|
|Protein length :||Met1-Leu155|
|Endotoxin :||< 1.0 EU per μg protein as determined by the LAL method.|
|Purity :||> 85 %as determined by SDS-PAGE.|
|Stability :||Samples are stable for up to twelve months from date of receipt at -70 centigrade.|
|Storage :||Store it under sterile conditions at -20 centigrade to -80 centigrade. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.|
|Reconstitution :||It is recommended that sterile water be added to the vial to prepare a stock solution of 0.2 mg/ml. Centrifuge the vial at 4ºC before opening to recover the entire contents.|
|Shipping :||In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.
Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
|Protein Refseq :||EHH16054|
