Frequently Asked Questions
How do I choose between recombinant and native Protein Purification?
Recombinant proteins offer defined sequence, consistent quality, and tag options. Native proteins may have post-translational modifications closer to physiological state. Match source to your assay sensitivity.
What specifications matter for Protein Purification?
Specific activity, purity (≥95% by SDS-PAGE typical), endotoxin level for cell-based assays, tag information, formulation buffer, and lot-to-lot consistency. Activity validation data is essential.
How should Protein Purification be stored to maintain activity?
Most proteins ship on dry ice and require -80°C long-term storage, -20°C for working aliquots. Avoid freeze-thaw cycles. Some products require specific buffer conditions and stabilizers.
Are bioactivity-validated products available?
Yes. Protein Purification include activity assays in the certificate of analysis. Specific activity is reported in U/mg with assay conditions specified, supporting quantitative experiments.
