MyBioSource, Inc. is a global life science reagent supplier originally founded in 2006 in Vancouver, British Columbia, by three entrepreneurs passionate about providing high-quality biological reagents worldwide. Since 2007, the company has been headquartered in San Diego, California, operating as a public company within the biotech, life sciences, and manufacturing sectors, serving customers worldwide with a lean team of roughly 25–30 employees.

The company's core mission is stated plainly: to provide top-quality research reagents worldwide, backed by a network of laboratories and manufacturers rather than in-house-only production. This distribution-focused model has allowed MyBioSource to build one of the largest catalogs in its space — currently spanning over 2 million individual products, up from an already substantial 1 million-plus listing in earlier years — covering thousands of species and analyte combinations to meet highly specific experimental requirements.

Its product range covers the essential toolkit of modern biomedical research: ELISA kits, recombinant proteins, monoclonal and polyclonal antibodies, secondary antibodies, CLIA kits, and a broad set of molecular biology reagents. The company also offers custom ELISA kit development for targets or species not already in its catalog, reflecting a service-oriented layer on top of its core distribution business. MyBioSource markets itself with an emphasis on competitive pricing, daily catalog updates, and worldwide shipping, positioning itself as a convenient single-source solution for academic, biotechnological, and pharmaceutical research institutions.

Worth noting for context: MyBioSource is a distinct, separate company from BioSource International — an unrelated life sciences reagent company (later acquired by Invitrogen/Thermo Fisher Scientific in 2005) that shares a similar name and product category but no corporate connection.
