The company was founded in 1998 by Jonathan Milner with co-founders professor Tony Kouzarides and David Cleevely, with the idea of making it easier for research scientists to buy antibodies across the web. Since its inception in 1998, the company has diversified from carrying only antibodies. It supplies antibody related products such as immunoassays (e.g. SimpleStep ELISA Kits), peptides, proteins and protein detection products (e.g. immunohistochemistry (IHC) staining kits). Abcam also has a portfolio of non-antibody related products such as biochemicals, cellular assays, and epigenetics kits (e.g. FirePlex Multiplex miRNA Kits).
