FSH ELISA Kit (Follicle Stimulating Hormone)


Human FSH ELISA kit is a reliable quantitative procedure for measuring follicle stimulating hormone (FSH) in human serum samples. This assay has a minimum sensitivity detection limit of 0.856 mIU/ml.


Follicle stimulating hormone (FSH) is a glycoprotein which is secreted by basophil cells, located in the anterior pituitary. It is just like to other glycoproteins being made up of an alpha and beta subunit. The immunological and biological properties of these glycoproteins is determined solely by the uniqueness of the beta subunits whilst the alpha subunits remain very similar structurally.

Alongside luteinizing hormone (LH), FSH is able to regulate the synthesis and secretion of female and male sex hormones via a negative feedback relationship, together they are able to control the growth and reproductive activities of gonadal tissues. Elevated concentrations have been identified after menopause, premature ovarian failure and after castration. Due to it being regulated by a negative feedback mechanism, the concentrations of FSH can be normalized by administration of estrogens.


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.

  • Microtiterwell Plate: Break apart strips which are coated with anti FSH monoclonal antibodies.
  • Standards 0-5: Concentrations 0, 5, 10, 20, 50, 100 mIU/ml. The standards are calibrated against international standard for immunoassay NIBSC code 92/510.
  • Enzyme Conjugate: Consisting of antibody conjugated to horseradish peroxidase.
  • Substrate Solution: Tetramethylbenzidine (TMB).
  • Stop Solution: 0.5M H2SO4; Avoid contact with the stop solution. It may cause skin irritations and burns.
  • Wash Solution (Concentrated).


The minimum sensitivity detection limit of follicle stimulating hormone (FSH) using current FSH ELISA kit was approximately 0.856 mIU/ml. The dynamic range for this assay is 5.0 – 100.0 mIU/ml.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
