Custom Premix Selecting "Custom Premix" option means that all of the beads you have chosen will be premixed in manufacturing before the kit is sent to you.
Native, chicken egg white lysozyme. Hydrolyzes β1,4 linkages between N-acetylmuramic acid (2-acetamido-2-deoxy-3-O-[1carboxymethyl]-glucopyranose) and N-acetyl-glucosamine residues in chitin. Also hydrolyzes β1,4 linkages between N-acetylmuramic acid and N-acetyl-glucosamine residues in peptidoglycans. Inhibits the biological activity of lipopolysaccharides from periodontopathic bacteria.
