About Kerafast

Kerafast is a Boston-based reagent company whose primary mission is to make unique laboratory-made research tools easily accessible to the global scientific community. Their portfolio includes cell lines, antibodies, small molecules, dyes, and more, many of which are not available elsewhere. Since their founding in 2011, researchers from more than 200 institutions worldwide have made their innovative reagents available through their online platform, where the materials can be quickly accessed without needing to go through the traditional Material Transfer Agreement process.

They handle all selling and shipping logistics for the providing laboratory, as well as return generous royalty payments from every sale. Procuring scientists can more easily discover and access unique reagents that are often unavailable elsewhere, while also funding the work of other researchers. This creates a global community of scientists contributing and accessing Reagents for the Greater Good to accelerate their own research as well as scientific progress overall.

In 2018, Kerafast merged with Absolute Antibody, a UK-based company with a vision to make recombinant antibody technology available to all researchers. The merger brought together two companies with a shared commitment to improving the selection of research tools available to the scientific community. In 2020 the companies became part of the LS Bio family of brands.
