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.

-
Add a certain amount of 2019 nCoV(S) into the sample. Calculate the recovery by comparing the measured value with the expected amount of 2019 nCoV(S) in the sample.
