This kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with 5-hydroxytryptamine. 5-hydroxytryptamine in the sample or standard competes with a fixed amount of biotin-labeled 5-hydroxytryptamine for sites on a pre-coated antibody specific to 5-hydroxytryptamine. Free components are washed off. After adding HRP-Streptavidin Conjugate (SABC), biotin specifically binds with streptavidin to form immune complexes. Wash off unbound conjugate. Add TMB substrate solution. Then, TMB was catalyzed by HRP to produce a blue color product that turned yellow after adding a stop solution. Read the O.D. absorbance at 450nm in a microplate reader. Compare OD450 value of sample with the standard curve through curve fitting software to determine the concentration of 5-hydroxytryptamine in the sample. The concentration of the target substance is inversely proportional to the OD450 value.

Assay Procedure Summary
Elisa实验原理图
  • Step 1: Wash the plate twice before adding the standard and sample.
  • Step 2: Add 50ul standard or sample into each well. Immediately add 50ul biotin-labeled antibody working solution into each well(The tip can't be reused after touching the liquid.), gently shake the plate for 1min, seal closely and statically incubate for 45 minutes at 37°C.
  • Washing: Wash the plate three times and immerse for 1min each time.
  • Step 3: Add 100ul HRP-Streptavidin Conjugate (SABC) working solution into each well, seal the plate and statically incubate for 30 minutes at 37°C.
  • Washing: Wash the plate five times and immerse for 1min each time.
  • Step 4: Add 90ul TMB substrate solution, seal the plate and statically incubate for 10-20 minutes at 37°C. (Accurate TMB visualization control is required.)
  • Step 5: Add 50ul stop solution. Read at 450nm immediately and calculate.

Standard Curve

This product is detected by QC department and meets performance required in the manual. (Laboratory Humidity: 20%-60%; Temperature: 18°C -25°C; Equilibrate TMB substrate to 37°C before staining. After adding into the ELISA wells, incubate for 15min at 37°C in dark.)

Due to different assay environments and operations, assay data below and standard curve are provided for reference. Experimenters should establish standard curve according to their own assay.

Recovery

Add a certain amount of 5-hydroxytryptamine into the sample. Calculate the recovery by comparing the measured value with the expected amount of 5-hydroxytryptamine in the sample.

Sample Type Recovery Range(%) Average(%)

EDTA plasma(n=10) 85-105 95
Heparin plasma(n=10) 91-102 98

Linearity

Dilute the sample with a certain amount of 5-hydroxytryptamine at 1:2, 1:4 and 1:8 to get the recovery range.
