LDHA Antibody

2012:

Western Blotting

LDHA Antibody detects endogenous levels of total LDHA protein.

Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the sequence of human LDHA. Antibodies are purified by peptide affinity chromatography.

Western Blotting

Western blot analysis of extracts from various cell lines using LDHA Antibody.

Lactate dehydrogenase (LDH) catalyzes the interconversion of pyruvate and NADH to lactate and NAD⁺ . When the oxygen supply is too low for mitochondrial ATP production, this reaction recycles NADH generated in glycolysis to NAD⁺ , which reenters glycolysis. The major form of LDH found in muscle cells is the A (LDHA) isozyme. The LDHA promoter contains HIF-1α binding sites (1). LDHA expression is induced under hypoxic conditions (2). During intensive and prolonged muscle exercise, lactate accumulates in muscle cells when the supply of oxygen does not meet demand. When oxygen levels return to normal, LDH converts lactate to pyruvate to generate ATP in the mitochondrial electron transport chain.
