This kit is based on indirect ELISA detection method and takes 3h assay time. The microplate provided in this kit has been precoated with antigen. HRP-antibody is used as detection antibody. Add standard and properly diluted sample into relevant well respectively. After incubation, wash unbound components. Add HRP-detection antibody, then it binds with HSPA5-Ab bound to precoated antibody. Wash unbound components 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 HSPA5-Ab in the sample by plotting standard curve. The concentration of the target substance is proportional to the OD450 value.

Recovery
Add a certain amount of HSPA5-Ab into the sample. Calculate the recovery by comparing the measured value with the expected amount of HSPA5-Ab in the sample.

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.
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.

Usage Notes
Step 1: Take out the required plate wells, add 50ul Cap/Det Ab into each well, then add 50ul Standard or Sample into individual well. (When adding standard or sample, the disposable tip lightly touches the liquid level. Change the disposable tips for different samples and standards.) Gently tap the plate for 10s to ensure thorough mixing then static incubate for 60 minutes at 37°C.
Washing: Wash the plate twice without immersion.
Step 2: Add 100ul HRP-Streptavidin (orange) into each well, seal the plate and static incubate for 30 minutes at 37°C.
Washing: Wash the plate five times without immersion.
Step 3: Add 90ul TMB substrate solution, seal the plate and static incubate for 10-20 minutes at 37°C. (Accurate TMB visualization control is required.)
Step 4: Add 50ul stop solution. Read at 450nm immediately and calculate.
