Research Area
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 fish ARO in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Materials provided
  • A 96-well Assay plate--The 96-well plate has been pre-coated with goat-anti-rabbit ARO antibody.
  • Standard (6 x 0.5 ml)--Dilute the standard at dilution series, read the OD values, and then draw a standard curve.
  • HRP-conjugated ARO (1 x 6 ml) --Bind to the anti-fish ARO antibody, and HRP catalyzes the TMB to elicit a chromogenic reaction.
  • Anti-fish ARO Antibody (1 x 6 ml)--React with both ARO in the samples/standards and HRP-conjugated ARO.
  • Wash Buffer (20x concentrate) (1 x 15ml) --Wash away unbound or free substances.
  • Substrate A (1 x 7 ml) --Mix with Substrate B and interacts with HRP, eliciting the solution turns blue.
  • Substrate B (1 x 7 ml) --Mix with Substrate A and interacts with HRP, eliciting the solution turns blue.
  • Stop Solution (1 x 7ml) --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

The Fish Aromatase (ARO) ELISA Kit is suitable for the quantitative detection of ARO in fish samples, including serum, plasma, and tissue homogenates. It has been validated with excellent sensitivity, high specificity, premium precision, high recovery, and lot-to-lot consistency. See the product instructions for more details.

This assay employs the competitive inhibition enzyme immunoassay technique. The microtiter plate has been pre-coated with goat-anti-rabbit ARO antibody. Standards or samples are added to the appropriate microtiter plate wells with an antibody specific for ARO and HRP-conjugated ARO. The competitive inhibition reaction is launched between with HRP-labeled ARO and ARO in the samples or standards with the anti-fish ARO antibody. The substrate solution is added to the wells and the color develops in opposite to the amount of ARO in the sample. The color development is stopped and the intensity of the color is measured.

ARO is the enzyme responsible for the aromatization of androgens to estrogen in many tissues, such as gonads, adipocytes, and the brain. It is important for sexual development. ARO helps make the estrogen that is conducive to fuel the growth of hormone-receptor-positive breast cancer. It may play a role in sex-determination. High levels of ARO was expressed at temperatures that yield female progeny in temperature-dependent sex determinant species. ARO also exerts a neuroprotective role. Many factors, including age, obesity, insulin, alcohol, and smoking, can enhance the activity of ARO.
