Proteintech offers a broad monoclonal antibody product line. Each Proteintech monoclonal antibody has a unique manufactured in-house clone number. The high specificity with one epitope target makes our monoclonal antibodies very efficient, reflecting in less background staining and low cross-reactivity with other proteins. Also, high homogeneity of Proteintech monoclonal antibodies ensures minimal batch-to-batch variations, making the results easy to reproduce.
