< 1.0 EU per μg of the protein as determined by the LAL method
1. Measured by its ability to bind human IgG1 in a functional ELISA. 2. Labeled biotin to FCGRT & B2M Heterodimer Protein, Human, Recombinant (His Tag) by a certain molar ratio; Using the Octet RED System, the affinity constant (Kd) of FCGRT & B2M Heterodimer Protein, Human, Recombinant (His Tag) bound to Conbercept was 0.1 μM.
A DNA sequence encoding the extracellular domain (Met1-Ser297) of human FCGRT (P55899-1) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1; A DNA sequence encoding the human B2M (P61770-1) (Met1-Met119) constructed the plasmid 2. The two plasmids were co-expressed and the FCGRT / B2M heterodimer was purified.
The recombinant heterodimer of human FCGRT/B2M comprises 384 (285+99) amino acids and has a calculated molecular mass of 43.5 (31.8+11.7) kDa. The apparent molecular mass of human FCGRT/B2M heterodimer is approximately 35 & 12 kDa respectively in SDS-PAGE under reducing conditions.
Lyophilized from sterile PBS, pH 7.4 Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.
Please refer to the specific buffer information in the hard copy of CoA.
In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature. Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.
安定性 & 保存条件
Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃ Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.
A hardcopy of COA with reconstitution instruction is sent along with the products. Please refer to it for detailed information.
