We are a B2B custom enzyme provider with decades of expertise in molecular biology, genome mining and protein purification.

Our product catalog features a wide range of proprietary enzymes, from advanced molecular amplification, to assay development and detection technologies... and that's only the beginning of what we have to offer!

We perform the difficult, time-consuming labor of perfecting each and every enzyme, to order, then it's packaged, labeled and shipped to you or your customer at a price point that can't be beat.

We make the hard stuff easy.
