HEPES
A premium, clinical-grade zwitterionic biological buffering agent engineered extensively for cell culture of diverse organisms, protein studies, and in vitro diagnostic assay kits. Sourced through China's first 100-ton continuous flow manufacturing process, it delivers high chemical purity and excellent water solubility to maintain stable physiological pH under various stress environments.
Chemical Name:
4-(2-Hydroxyethyl)-1-piperazineethanesulfonic acidApplications & Uses:
- Zwitterionic buffering agent extensively used in cell culture media for diverse organisms
- Stabilizing acidic and sensitive active components in cosmetic formulations and dermatological products
- Buffering system for protein purification, characterization, and enzyme kinetics studies
- Buffer preparation in biochemistry diagnostic kits, molecular biology reagents, and CLIA assays
Benefits:
- Outstanding high purity and excellent water solubility for rapid, clear buffer preparation
- Robust process design ensuring minimal lot-to-lot and batch-to-batch variation
- Complete international compliance with REACH, K-REACH, CDE, and CMDE registrations
