Home mx-auto"> This kit is based on Double antibody-Sandwich ELISA detection method and takes 4h assay time. The microplate provided in this kit has been precoated with anti GLUL antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add biotinylated detection antibody. Then, it binds with GLUL bound to precoated antibody. Wash unbound components and add HRP-Streptavidin Conjugate (SABC). Wash unbound components again and 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. Calculate the concentration of GLUL in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

- Assay Procedure Summary
-
- Step 1: Add 100ul standard or sample into each well, seal the plate and statically incubate for 90 minutes at 37: Add 100ul biotin-antibody working solution, seal the plate and statically incubate for 60 minutes at 37min each time.
- Step 3: Add 100ul HRP-Streptavidin Conjugate (SABC) working solution, 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 GLUL into the sample. Calculate the recovery by comparing the measured value with the expected amount of GLUL in the sample.

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