Luteinizing hormone 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 1.2 mIU/ml.
Luteinizing hormone (LH) is a glycoprotein which is produced in both females and males in response to luteinizing hormone-releasing hormone (LH-RH or Gn-RH) from the anterior pituitary gland. It has a molecular weight of 30,000 daltons and consists of alpha and beta chains that are associated non-covalently. The α-subunit is identical to the other pituitary hormones namely chorionic gonadotropin (hCG), follicle stimulating hormone (FSH) and thyroid stimulating hormone (TSH), whilst the β-subunit is unique and confers the biological activity to the molecule. The α -subunit is made up of 89 amino acid residues and the β-subunit consists of 129 amino acids, with the carbohydrate content being between 15%-30%.
The importance of determining luteinizing hormone (LH) is to ascertain the homeostasis of fertility regulation through the hypothalamic-pituitary-gonadal axis. 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. In the differential diagnosis of pituitary, gonadal dysfunction or hypothalamic, a number of assays that measure the concentration of LH have been routinely used in conjunction with FSH due to the fact that their roles are inter-related. Other uses include pinpointing ovulation, determining menopause and monitoring endocrine therapy.
Reagents which are supplied with the following luteinizing hormone ELISA kit, please following instructions for storage conditions.
1. Microtiter Plate: monoclonal anti-LH antibody coated.

The minimum sensitivity detection limit of LH using current human luteinizing hormone ELISA kit was approximately 1.2 mIU/ml. The dynamic range for this assay is 10.0 – 200.0 mIU/ml.
