L-Lactate Dehydrogenase (L-LDH) material number and pack size: Material Number Pack Size 10021415103 custom fill
- Dehydrogenase that catalyzes the interconversion of specific for L(+)-lactate to pyruvate.
- Use L-Lactate Dehydrogenase in a variety of diagnostic tests for the removal of pyruvate in determinations working with NADH (i.e., triglycerides, lipase, aldolase, aminotransferases, glutamate dehydrogenase).
