Human LH ELISA kit is a reliable quantitative procedure for measuring luteinizing hormone (LH) in human serum samples. This assay has a minimum sensitivity detection limit of 1.27 mIU/ml.
Luteinizing hormone (LH) has a molecular weight of 30,000 daltons and it consists of alpha and beta chains that are associated non-covalently. The α -subunit is 89 amino acid residues and the β-subunit consists of 129 amino acids, with the carbohydrate content being between 15%-30%. The hypothalamic-pituitary-gonadal axis controls fertility and measuring LH is crucial to determining this. Also, it can help the advent of in vitro fertilization (IVF) procedure in order to overcome infertility that is associated to various problems. Over the many year the vast improvement in methodology from bioassays that are technically very demanding to the many simple and rapid immunoassays have helped this cause considerably.
All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.
