Home mx-auto"> This kit is based on Competitive-ELISA detection method and takes 2h assay time. The microplate provided in this kit has been precoated with PRL. PRL in the sample or standard competes with a fixed amount of biotin-labeled PRL for sites on a pre-coated antibody specific to PRL. 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 PRL in the sample. The concentration of the target substance is inversely proportional to the OD450 value.

- Assay Procedure Summary
-
- 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 37min 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 37min each time.
- Step 4: Add 90ul TMB substrate solution, seal the plate and statically incubate for 10-20 minutes at 37: Add 50ul stop solution. Read at 450nm immediately and calculate.

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

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

-
Intra-assay Precision: samples with low, medium and high concentration are tested 20 times on the same plate.
Inter-assay Precision: samples with low, medium and high concentration are tested 20 times on three different plates.
