LSBio provides high-quality antibodies, proteins, ELISA and assay kits to researchers worldwide.

Founded in 1995, LSBio was established as a molecular pathology company with a focus on protein localization in diseased human tissues by IHC. Through the experience gained by executing thousands of IHC studies, and generating and testing many thousands of antibodies, LSBio has become a world leader in the antibody industry, with a reputation for excellence.

LSBio’s catalog includes 530,000 monoclonal and polyclonal antibodies to 19,000 targets. Antibodies are available for most species and all major research applications, such as IHC, IF, WB and FACS.
