  • Product overview

    Abcam’s Testosterone in vitro competitive ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of Testosterone in serum and plasma.

    A 96-well plate has been precoated with anti-Testosterone antibodies. Samples and the Testosterone-HRP conjugate are added to the wells, where Testosterone in the sample competes with the added Testosterone-HRP for antibody binding. After incubation, the wells are washed to remove unbound material and TMB substrate is then added which is catalyzed by HRP to produce blue coloration. The reaction is terminated by addition of Stop Solution which stops the color development and produces a color change from blue to yellow. The intensity of signal is inversely proportional to the amount of Testosterone in the sample and the intensity is measured at 450 nm.

Testosterone is a biochemical and it should be same in all the species so theoretically this kit would work with testosterone from all the species. We however have tested it with human samples only.

I can confirm the lab used PBS to dilute serum samples when validating the kit.

This is most likely due to matrix effect which affect measurement of analyte of interest in ELISA when undiluted serum or plasma samples are used. Matrix effect can arise from a number of matrix components such as phospholipids, carbohydrates, and endo...

The test measures both bound and free Testosterone.

Testosterone Human Elisa Kit

Excellent Below average 2/5 (Ease of Use)
This Kit is very easy to use. It provides all the reagent and it is very good for data output as it takes less than 3 hours to be performed.
The kit is designed for Human Serum of plasma. However, it works very well on mouse serum.
Standards provided with the kit, produce a reliable standard curve as shown in the picture below.

I confirmed with the lab and unfortunately do not have good news:
The heavily hemolyzed samples would have an great influence on the results. We do not know of any protocol trick to circumvent this and therefore recommend to collect new sampl...
