According to a recent survey, scientists most frequently purchase pre-made catalog antibodies from Santa Cruz Biotechnology, BD Biosciences (NYSE: BDX), Sigma-Aldrich (NASDAQ 100: SIAL), R&D Systems (NASDAQ: TECH) and Calbiochem. However, since no single company has a sufficiently broad product mix to accommodate all of the research applications for which antibodies are used, scientists routinely purchase antibodies from multiple suppliers.
