For procurement managers and research scientists, understanding the critical specifications of Recombinant Bovine Basic Fibroblast Growth Factor (rbbFGF) is fundamental to making informed purchasing decisions. The quality and performance of this vital growth factor depend on precise manufacturing processes and adherence to strict quality standards. As a leading supplier, we aim to demystify these specifications to help you buy with confidence.

When sourcing rbbFGF, key specifications to scrutinize include purity, appearance, expression system, molecular weight, and biological activity. Purity is typically assessed by SDS-PAGE and HPLC, with levels often exceeding 95%. Higher purity ensures that the growth factor is the primary active component, minimizing interference from impurities that could affect experimental results. When you buy rbbFGF, always look for documented purity levels from your manufacturer.

The appearance of rbbFGF is generally described as a white or off-white powder, reflecting its lyophilized state for optimal stability. Its molecular weight, around 17.2 kDa for bovine recombinant forms produced in E. coli, is another important identifier. The expression system (e.g., E. coli) is relevant as it influences post-translational modifications and potential downstream purification challenges. Understanding these details helps in selecting the most appropriate product for your application.

Biological activity, often measured by its ability to stimulate cell proliferation at low concentrations (e.g., < 1 ng/ml for half-maximum stimulation), is the ultimate test of a growth factor's efficacy. This parameter confirms that the protein is not only pure but also functionally active. When you purchase rbbFGF, ensure the supplier provides data on its biological activity.

Stability and reconstitution are also crucial considerations. Lyophilized rbbFGF is typically stable when stored at -15°C or below, often with a shelf life of 24 months. Proper reconstitution protocols, usually involving sterile distilled water or a buffer with BSA, are essential to maintain the protein's activity. Guidance on storage of reconstituted solutions (e.g., at 2-8°C for a week or -20°C/-80°C for longer periods) is vital for end-users. As a supplier, we provide comprehensive documentation to guide your use.

We are committed to transparency and quality, offering Recombinant Bovine Basic Fibroblast Growth Factor with detailed specifications to meet the rigorous demands of research and biopharmaceutical development. We encourage you to purchase our rbbFGF and to reach out to us for any clarification on product specifications. Understanding these details ensures you buy the most effective growth factor for your project.
