Product Description

Recombinant Human Complement Factor B (260-764 a.a.), Sf9 is a protein derived from the Sf9 insect cell line through genetic engineering techniques. Belonging to the complement system, it plays a vital role in the immune response by activating the alternative pathway. This protein, with a molecular weight of approximately 55-60 kDa, is involved in the amplification and regulation of the complement cascade, contributing to the clearance of pathogens and immune complex formation. Its recombinant form offers a valuable tool for research and development in immunology and related fields.

Reconstituted store at -20°C or -80°C.We recommend that single use aliquots are prepared to avoid freeze-thaw cycles.

1. Thaw the vial on ice, spin briefly
2. Prepare single-use or stock aliquots. This stage will depend on your final application so please adapt as appropriate. All our proteins are supplied carrier protein-free. If compatible with your work and you are storing at lower concentrations (<50 ug/ml) adding carrier protein is highly advised (usually 1% w/v high purity BSA or equivalent – ensure all buffers are sterile-filtered).
3. Prepare single-use aliquots whenever possible to avoid freeze-thaw cycles which can damage the proteins and reduce bioactivity. Store aliquots at -70 °C (or -20 °C)
4. We recommend sterile filtering after dilution in media or the final working solution
