Human CD19 (20-278) is fused with a human IgG1 Fc tag at the C-terminus, and has a calculated MW of 55.1 kDa. The reducing (R) protein migrates at 62-70 kDa in SDS-PAGE due to glycosylation. Protein sequence: Pro 20 - Pro 278 of UniProt Accession Number P15391
gene name CD19
host species Human
production host HEK293
tags Fc Tag
purity >95% as determined by SDS-PAGE
endotoxin The protein was purified from endotoxin-free mammalian cell culture under strict endotoixn-free conditions. No endotoxin was detected in final prodcut using LAL method to the method's sensitivity level (< 1.0 EU/ug).
formulation Protein in [50 mM tris, 100 mM glycine, pH7.5] was 0.22 ?m filtered before lyophilized. Usually protectant (mannitol or trehalose) was added before lyophilization.
reconstitution Reconstitute lyophilized powder with water to a concentration of no less than 100 ug/ml, solubilize at RT for 30 min with occasional gentle mixing. It is recommended that 0.1% of HSA be added as a carrier protein for long term storage.
concentration Lyophilized Powder
shipping Shipped at ambient conditions.
storage Lyophilized form is stable for 2 weeks at room temperature or for 12 months at 4-8°C. Keep at -20°C or lower for long term storage. After reconstitution, store at 4°C for 2-7 days or at below -20°C for up to 3 months.
