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 an 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 trans (on other cells) with TNFRSF14.
Source Recombinant Human BTLA Protein is expressed from Expi293 with His tag and Avi tag at the C-terminal. It contains Lys31-Ser150.
Molecular Weight The protein has a predicted MW of 16.7 kDa. Due to glycosylation, the protein migrates to 35-45 kDa based on Tris-Bis PAGE result.
Endotoxin Less than 1 EU per μg by the LAL method.
Purity >95% as determined by Tris-Bis PAGE.
>95% as determined by HPLC.
Formulation Lyophilized from 0.22 μm filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.
Reconstitution Centrifuge tubes before opening. Reconstituting to a concentration more than 100 μg/ml is recommended. Dissolve the lyophilized protein in distilled water.
Storage -20 to -80℃ for 12 months as supplied from the date of receipt.
-20 to -80℃ for 3-6 months in an unopened state after reconstitution.
2-8℃ for 2-7 days after reconstitution.
Notes Recommend to aliquot the protein into smaller quantities for optimal storage. Please avoid freeze-thaw cycles.
