Frequently Asked Questions
Which enzymes are included in Diagnostic Enzymes (ELISA & Assay Grade)?
Included are HRP (EC 1.11.1.7), alkaline phosphatase (AP, EC 3.1.3.1), and glucose oxidase (GOx) sourced from horseradish, E. coli, and Aspergillus.
What are the recommended optimal pH and temperature ranges?
Use within optimal pH 5.0–8.0 and temperature 20°C–37°C to maintain assay-grade performance.
How do I interpret the activity specifications for HRP and AP?
HRP is specified at 200–400 U/mg; AP is specified at 1,000+ DEA U/mg. These values represent measured activity per mg for dosing control.
What is the shelf life and how should I store the enzymes?
Shelf life is 12 months when sealed and stored at -20°C or 2–8°C. Follow COA/TDS storage instructions for best performance.
Do you offer small quantities for research and larger quantities for production?
Yes. MOQ is 1 g for research, 100 g for bulk orders; packaging is available from 1 g to 1 kg with custom options.
