Activity testing is in progress. It is theoretically active, but we cannot guarantee it. If you require protein activity, we recommend choosing the eukaryotic expression version first.

C1QA Protein, Human, Recombinant (GST) is expressed in E. coli expression system with GST tag. The predicted molecular weight is 50.58 kDa and the accession number is P02745.

Human

E. coli

complement component 1, q subcomponent, A chain

The Human C1QA (P02745) (Glu23-Ala245) was fused with the GST tag at the N-terminus.

≥ 75 % as determined by SDS-PAGE. ≥ 90 % as determined by SEC-HPLC.

A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.

It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
