Testing in progress
A DNA sequence encoding the mouse CD79A (NP_031681.2) (Met1-Arg137) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 1; A DNA sequence encoding mouse CD79B (NP_031681.2) (Met1-Asp158) was fused with a polyhistidine tag at the C-terminus, constructed the plasmid 2. The two plasmids were co-expressed and the mouse CD79A & CD79B heterodimer was purified.
The recombinant mouse CD79A & mouse CD79B heterodimer comprises 264 (120+144) amino acids and has a calculated molecular mass of 30.3 (13.8+ 16.5) kDa. The apparent molecular mass of the recombinant protein is approximately 34.6, 28.3 and 24.1 kDa respectively in SDS-PAGE under reducing conditions.
Lyophilized from sterile PBS, pH 7.4. 1. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization. Specific concentrations are included in the hardcopy of COA. 2. Please contact us for any concerns or special requirements.
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.
