Cell Lysate Extracts. Great protocols for cell lysis preparation from a variety of cell types. There are numerous methods of cell stimulation and lysis. For a given protein, Upstate’s Laboratories determine the specific treatment upon initial testing of its products. It is important to select the correct cell line, stimulation procedure (if any), and lysis protocol. Upstate. - [Read Cell Lysate Extracts]
