Unlocking the Power of Primary Antibodies: Essential Tools for Cutting-Edge Research



Primary antibodies bind directly to specific antigens with high specificity and affinity for purposes such as antigen purification, detection, and quantification. These antibodies can be developed as monoclonal antibodies, which target a single epitope on the antigen, or polyclonal antibodies, which recognize multiple different epitopes on the antigen. They are typically generated in animal hosts, such as rats, rabbits, mice, goats, and other species.


Primary antibodies can be raised against any antigen of research interest, including proteins, peptides, carbohydrates, and other small molecules. They can also be designed to recognize post-translational modifications like phosphorylation, acetylation, methylation, and glycosylation. As such, primary antibodies are essential tools for analyzing cellular components at the molecular level and identifying proteins that may be involved in or cause disease.


We offer over 65,000 primary antibodies, both unconjugated and conjugated, targeting more than 14,000 antigens. All antibodies are validated across various research applications and with samples from multiple species. Additionally, a growing number of antibodies have undergone validation through protein arrays or knockout models to ensure specificity.

  •  Immunohistochemistry: Anti-Cytokeratin 18 Antibody 


Many IHC protocols involve binding primary antibodies to target antigens on tissue sections, followed by secondary antibody incubation. The detection method depends on the type of secondary antibody used.


  •  Immunoprecipitation: Anti-Vimentin Antibody
