This track shows intensities of a microarray spotted with short peptides derived from the S protein. Fifty-five sera from convalescent COVID-19 patients and 18 control sera were screened on the peptide microarray for both IgG and IgM responses. When comparing the microarry tracks, note that they are from patients at difference stages of the infection.

A total of 211 peptides were synthesized and conjugated to BSA. The conjugates along with control proteins were prepared in triplicate at three dilutions.
