Luteinizing Hormone ELISA kits are assays designed to measure levels of the protein Luteinizing Hormone in biological samples, such as plasma, serum, culture extracts, and cell lysates. Luteinizing hormone (LH) is a glycoprotein hormone produced by the gonadotrophin cells in the anterior pituitary gland. Along with follicle-stimulating hormone, LH is crucial for the regulation of reproductive functions. In humans, the LH protein is heterodimeric, comprised of chorionic gonadotropin alpha (CGH) and luteinizing hormone beta polypeptide (LHB). In both males and females, LH signals endocrine cells in the gonads to produce androgens.
