Preguntas frecuentes
How do I choose between recombinant and native proteins?
Recombinant proteins offer consistent quality, defined sequence, and tag options for purification or detection. Native proteins may have post-translational modifications closer to physiological state. Match source to your assay requirements.
What specifications matter for protein and enzyme research?
Specific activity, purity (≥95% by SDS-PAGE typical), endotoxin level for cell-based assays, storage conditions, tag information (His, GST, FLAG), formulation buffer, and lot-to-lot consistency.
How should proteins be stored to maintain activity?
Most proteins ship on dry ice and require -80°C storage long-term, -20°C for working aliquots. Avoid repeated freeze-thaw cycles — aliquot upon first thaw. Some enzymes have specific buffer requirements for stability.
Are bioactivity-verified enzymes available?
Yes. Enzymes include activity assays in the certificate of analysis. Specific activity is reported in U/mg, with assay conditions specified. Compare lot-specific data for quantitative work.
