Cellular Marker & Epitope Tag Antibodies Overview

Cellular Marker & Epitope Tag Antibodies provide essential reagents for identifying, visualizing, and tracking proteins across biological systems. Cellular markers are endogenous proteins used to distinguish specific cell types, lineages, or cellular states, such as CD proteins for immune cells, keratins for epithelial cells, and GFAP for astrocytes. Epitope tags, by contrast, are short peptide sequences engineered into recombinant proteins — common examples include FLAG, HA, c-Myc, and His-tags. Antibodies against these sequences enable straightforward detection and purification in systems where direct protein-specific antibodies are not available or are impractical.

Together, these antibodies bridge foundational research with applied biomedical science. The Cellular Marker & Epitope Tag Antibodies category supports immunology, neuroscience, oncology, stem cell research, molecular biology, and protein engineering. Because of their versatility and broad adoption, they remain indispensable across discovery and translational pipelines.
