Optimizing conditions for the microarraying of protein antigens onto glass slides were studied. Various vendors, surface functional groups, buffers, and fixatives were evaluated to enhance protein binding. A total of 125 pg of human immunoglobulin was detectable with this assay system, suggesting that protein microarray can be applied for routine immunodiagnosis.
