Product Description	Recombinant Human BTLA Protein is expressed from HEK293 with hFc tag at the C-Terminus.It contains Lys31-Ser150.
Product Background	B- and T-lymphocyte attenuator (BTLA; CD272) is a 35 kDa type I transmembrane glycoprotein in the CD28 family of T cell costimulatory molecules. BTLA is a inhibitory receptor on lymphocytes that negatively regulates antigen receptor signaling via PTPN6/SHP-1 and PTPN11/SHP-2. BTLA may interact in cis (on the same cell) or in trans (on other cells) with TNFRSF14.
Product Category	Recombinant Protein

Target	BTLA
Synonyms	CD272; BTLA; BTLA1; FLJ16065; MGC129743
Gene/Protein ID	Q7Z6A9-1
Species	Human
Exact Sequence	Lys31-Ser150
Molecular Weight	The protein has a predicted MW of 40.5 kDa. Due to glycosylation, the protein migrates to 60-70 kDa based on Tris-Bis PAGE result.
Activity	Immobilized Human BTLA, hFc Tag at 0.2ug/ml (100ul/Well) on the plate. Dose response curve for Biotinylated Anti-BTLA Antibody, hFc Tag with the EC50 of 11.4ng/ml determined by ELISA. See testing image for detail.
Product Tag	C-hFc
Express System	HEK293
Purity	> 95% as determined by Tris-Bis PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1EU per ug by the LAL method.

Form	Lyophilized
Shipping	Shipped at ambient temperature.
Formulation	Lyophilized from 0.22um 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 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.
Stability And Storage	Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles.
