Recombinant Human BTLA / CD272 was expressed from HEK293. Its molecular weight is 40.8KD. Protein sequence: Lys31-Leu150 of Uniprot accession number Q7Z6A9.
gene name BTLA
alias BTLA, Anterior gradient 3, protein disulphide isomerase family member, AG-3, AG3, BCMP11, HAG3, PDIA18, hAG-3
host species Human
production host HEK293
tags C-Fc
purity Greater than 95% as determined by reducing SDS-PAGE.
endotoxin Less than 0.1 ng/ug (1 IEU/ug) as determined by LAL test.
formulation Protein in [20mM PB,150mM NaCl,pH7.4] was 0.22 um filtered before lyophilized. Usually protectant (mannitol or trehalose) was added before lyophilization.
reconstitution Reconstitute lyophilized powder with water to no less than 100 ug/ml, solubilize at RT for 30 min with occasional gentle mixing. It is recommended that 0.1% HSA (SDP1139) be added as a carrier protein for long term storage.
shipping Ship at ambient conditions
storage Lyophilized form is stable at room temperature for 3 weeks. Keep at -20°C for long term storage. After reconstitution, store at 4°C for 2-7 days or at below -20°C for up to 3 months.
