Frequently asked questions
What is L-Lactic Dehydrogenase (LDH) from bovine heart used for?
L-Lactic Dehydrogenase is primarily used in clinical diagnostics for measuring lactate levels in blood, urine, or other biological fluids, as well as in biochemical research for studying metabolic pathways.
What is the molecular formula and molecular weight of L-Lactic Dehydrogenase?
L-Lactic Dehydrogenase is a protein enzyme, so it has no single small-molecule formula. It is a tetramer of polypeptide subunits of about 35 kDa each, giving a native molecular weight of about 140 kDa.
How should L-Lactic Dehydrogenase be stored?
Store at 2–8°C to maintain stability; avoid freeze-thaw cycles and protect from light exposure.
What grade or purity is available for L-Lactic Dehydrogenase?
Molekula supplies biochemical-grade LDH with ≥95% purity (activity-based) for research and diagnostic applications.
Can Molekula supply L-Lactic Dehydrogenase in bulk quantities?
Yes, we offer bulk packaging options (e.g., 1g, 5g, 10g+) for industrial or large-scale research applications—contact us for pricing and lead times.
What documentation comes with an order of L-Lactic Dehydrogenase?
