Triiodothyronine ELISA Kit


Human triiodothyronine ELISA kit can be used to reliably detect levels of human T3 (triiodothyronine) present in serum or plasma samples. The detection sensitivity of assay is 0.1 ng/ml.


Thyroid hormones play essential roles in the proper development and differentiation of many cells within the human body. triiodothyronine (T3) is a tyrosine-based hormone that is produced by the thyroid gland and is a useful marker for hyperthyroidism and hypothyroidism diagnosis. One of the major carrier of circulating thyroid hormones is thyroxine-binding globulin (TGB).

This human T3 ELISA kit has been specifically designed for analysing concentrations of total triiodothyronine (T3) and thereby acting as an ideal marker for various disease conditions. There are a number of pathological and physiological stimuli that can influence thyroid hormone synthesis and any deficiencies or excess of thyroxine can cause many disorders. The level of T3 is found to be normal in individuals with euthyroid, whereas in hyperthyroid patients it is increased and in hypothyroid patients it is decreased.


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.

  • Microtiterwells, 12 x 8 (break apart) strips: Wells coated with anti T3 antibody.
  • Assay Reagent.
  • Control Low and Control High. Containing triiodothyronine.
  • Standard 0-5: Concentrations: 0-10.0 ng/ml. Made up from anti-human T3.
  • Substrate Solution: Tetramethylbenzidine (TMB).
  • Enzyme Conjugate: Consisting of human T3 antibody conjugated to horseradish peroxidase (HRP).
  • Stop Solution: 0.5 M H2SO4.
  • Wash Solution 40x (Concentrated).


The minimum detectable sensitivity limit of triiodothyronine (T3) using current human T3 ELISA kit was < 0.1 ng/ml. The standard range was calculated to be between 0.5 –  10.0 ng/ml.

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

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.

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.

You are my first point of contact when I am looking to purchase ELISA. You have such an easy and simple system, yet it is very effective.
