Malate Dehydrogenase, chemically modified material number and pack size: Material Number Pack Size 11866109103 custom fill
- Dehydrogenase that catalyzes the interconversion of malate to oxaloacetate.
- Use Malate Dehydrogenase in diagnostic tests for the determination of aspartate aminotransferase or in applications for citric and acetic acid testing. The chemical modification generates an increased liquid stability of the enzyme.
