Collection: PRIMARY ANTIBODIES 

Primary antibodies play a critical role in the detection and identification of specific target molecules, such as proteins or antigens, using immunological assays. “Primary” refers to the fact that these are the initial antibodies that directly bind to the target of interest. The primary antibody-antigen interaction is a fundamental step in immunohistochemistry, immunofluorescence, enzyme-linked immunosorbent assay, Western blotting, chromatin immunoprecipitation, protein arrays, and flow cytometry. Our antibodies have been validated to ensure specificity and sensitivity critical for reliable results.
