Frequently Asked Questions

How do I choose the right Enzymes for my experiment?
Match the product to your assay: cell culture grade for biological work, molecular biology grade for nucleic acid applications, and pharmaceutical grade for sensitive workflows. Check endotoxin limits and animal-origin status.
What specifications matter for Enzymes?
Purity (HPLC), enantiomeric excess for chiral biomolecules, endotoxin levels for cell culture, animal-component-free status, lot-specific certificate of analysis, and storage stability data.
Are animal-component-free options available?
Yes. For biopharmaceutical and stem cell applications, animal-origin-free enzymes are stocked with documented sourcing. Match grade to your downstream application requirements.
How should Enzymes be stored?
Most biochemicals require refrigerated (2-8°C) or frozen (-20°C) storage. Avoid repeated freeze-thaw cycles by aliquoting upon first use. Some products require -80°C for long-term stability.
