Two passage reference cultures in our signature KWIK-STIK format.


Some laboratory applications require strains that are fewer passages from the original reference culture. For those special instances, we offer KWIK-STIK Plus, which combines microorganisms that are just two passages from their reference strains, with our signature KWIK-STIK format.
