When you think about choosing cytokines and growth factors, you don’t necessarily think about price shopping. Think again. Envigo collects thousands of submaxillary glands from mice and then processes these tissues to harvest the growth factors. With ready access to large quantities of tissues, Envigo has the world's best and most competitively priced selection of EGF and NGF material, including NGF 2.5S and NGF 7.0S. We also carry a wide-selection of human, mouse and rat cytokines. So even if you aren’t looking for best price and selection, you have found it.
