Product Details


The Rat Testosterone/T ELISA Kit is designed for the quantitative determination of endogenic rat testosterone concentrations in serum, plasma, cell culture supernates, or tissue homogenates. This assay employs the competitive inhibition enzyme immunoassay technique. Standards or samples are added to the appropriate goat-anti-rabbit testosterone antibody-pre-coated microtiter plate wells with the anti-rat testosterone antibody and HRP-conjugate. The competitive inhibition reaction is launched between with HRP labeled testosterone and unlabeled testosterone in the sample or standard with the anti-rat Testosterone antibody. Substrate A and B solution are mixed and then added to the wells, and the color turns blue. The color development is stopped, and the intensity of the color is opposite to the amount of DHT in the sample. Read the OD value with the Microplate reader and calculated the DHT concentration referring to the standard curve. This kit has been quality tested by multiple criteria, including sensitivity, specificity, precision, linearity, recovery, and lot-to-lot consistency.

Testosterone is a hormone produced by the testes and the adrenal gland. It plays an important role in muscle mass, bone strength, hair growth, and sexual function. Low levels of testosterone can cause low energy, poor concentration, depression, low libido, erectile dysfunction, and other symptoms.

Intra-assay Precision (Precision within an assay): CV%<15%      
Three samples of known concentration were tested twenty times on one plate to assess.  
Inter-assay Precision (Precision between assays): CV%<15%      
Three samples of known concentration were tested in twenty assays to assess.    
To assess the linearity of the assay, samples were spiked with high concentrations of rat testosteronen in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.
  Sample Serum(n=4)

Materials provided
  • A 96-well Assay plate -- The 96-well plate has been pre-coated with goat-anti-rabbit Testosterone antibody.
  • Standard 6 x 0.5 ml -- Dilute the standard at dilution series, read the OD values, and then draw a standard curve.
  • Anti-Testosterone Antibody 1 x 6 ml -- Act as the detection antibody.
  • HRP-conjugated Testosterone 1 x 6 ml -- Bind to the DHT antibody, and HRP catalyzes the substrate A and B to elicit a chromogenic reaction.
  • Wash Buffer (20 x concentrate) 1 x 15 ml -- Wash away unbound or free substances.
  • Substrate A 1 x 7 ml -- Mix with substrate B, and the TMB is catalyzed by HRP to develop color.
  • Substrate B 1 x 7 ml -- Mix with substrate A, and the TMB is catalyzed by HRP to develop color.
  • Stop Solution 1 x 7 ml -- Stop the color reaction. The solution color immediately turns from blue to yellow.
  • Four Adhesive Strips (For 96 wells)
  • An Instruction manual
Materials not provided
  • A microplate reader capable of measuring absorbance at 450 nm, with the correction wavelength set at 600 nm - 630 nm.
  • An incubator that can provide stable incubation conditions up to 37°C±5°C.
  • Centrifuge
  • Vortex
  • Squirt bottle, manifold dispenser, or automated microplate washer
  • Absorbent paper for blotting the microtiter plate
  • 50-300ul multi-channel micropipette
  • Pipette tips
  • Single-channel micropipette with different ranges
  • 100ml and 500ml graduated cylinders
  • Deionized or distilled water
  • Timer
  • Test tubes for dilution
