Product overview
Lactate Dehydrogenase (LDH) Assay Kit (Fluorometric) (ab197000) provides a quick and easy method for monitoring Lactate Dehydrogenase (LDH) activity in a wide variety of samples. In this assay, LDH converts lactate into pyruvate and NADH, which reacts with the specific fluorescent probe to generate an intense fluorescent product (Ex/Em = 535/587 nm).
This kit is simple, highly sensitive and high-throughput adaptable and can detect LDH activity as low as 1 µU/mL.
LDH assay protocol summary:
- add samples and standards to wells
- add reaction mix
- analyze with microplate reader every 2-3 min for 10-30 min -
Notes
Lactate dehydrogenase (LDH, L-Lactate NAD oxidoreductase, EC 1.1.1.27) is an ubiquitous enzymes among vertebrate organisms which catalyzes the reversible conversion of pyruvate to lactate, with concomitant conversion of NADH and NAD+. LDH is cytoplasmic in its cellular location and in any one tissue is composed of one or two of five possible isoenzymes. During tissue damage, LDH is released into the bloodstream; therefore it serves as a marker for various diseases and common injuries.
