Frequently Asked Questions
What is Ficin (EC 3.4.22.3) and what type of enzyme is it?
Ficin is a plant-derived cysteine protease from Ficus carica (fig latex). It cleaves peptide bonds to produce protein fragments and peptides for research and processing applications.
What are the recommended pH and temperature ranges for Ficin?
For best performance, use Ficin within pH 5.0–8.0 and 45°C–65°C. Activity and fragment profiles can change outside these ranges.
How should I interpret the activity specification (0.5–2.0 U/mg, casein assay)?
The activity range reflects measured enzyme units per milligram using a casein assay. Higher activity typically supports faster proteolysis at the same dosage; confirm final dosing with your specific substrate and endpoint.
Can Ficin be used to generate Fab and Fc fragments from IgG?
Yes. Ficin is commonly used to digest IgG into Fab and Fc fragments and is often considered as an alternative to papain for antibody engineering and diagnostic research.
What storage conditions help maintain Ficin activity over time?
Store sealed at -20°C when possible. The shelf life is 12 months when kept sealed and protected from moisture; avoid repeated warm exposure during handling.
What should I send to get a wholesale ficin quote?
Send the product (ficin powder, activity 0.5–2.0 U/mg, casein assay), your application, the quantity per order or per month, the pack size you prefer (100 g, 500 g or 1 kg) and the destination country. Pricing for larger volumes is quoted per order, and each lot ships with its CoA.
