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 / Antibody discovery / Immune checkpoint proteins

Protein	BTLA
Synonyms	CD272; BTLA; BTLA1; FLJ16065; MGC129743
Accession	Q7Z6A9-1
Species	Human
Biotinylated	no
Amino Acid Range	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 Bis-Tris PAGE result.
Activity	Immobilized Human HVEM, His Tag at 2ug/ml (100ul/Well) on the plate. Dose response curve for Human BTLA, hFc Tag with the EC50 of 7.2ng/ml determined by ELISA (QC Test). See testing image for detail.
Product Tag	C-hFc
Expression System	HEK293
Purity	> 95% as determined by Bis-Tris PAGE;> 95% as determined by HPLC
Endotoxin	Less than 1 EU 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	Dissolve the lyophilized protein in distilled water. It is recommended to resuspend at 0.5 mg/mL if the lyophilized powder is 100 ug or less, at 1mg/ml for 500ug or 1mg lyophilized powder. Do not mix by vortex or vigorous shaking.
Stability And Storage	-20 to -80°C for 12 months as supplied from date of receipt.；-80°C for 3 months after reconstitution.；Recommend to aliquot the protein into smaller quantities for optimal storage. Please minimize freeze-thaw cycles.
