Human Sertoli Cell Lysate (HSerC Lysate) is prepared from early passage Human Sertoli Cells using a modified RIPA buffer (50 mM Tris-HCl pH 7.2, 150 mM NaCl, 1% NP-40, 1mM EDTA, 1 mM EGTA, 0.4 mM PMSF, 5 µg/ml aprotinin, 5 µg/ml leupeptin, 1 µg/ml pepstatin, 1 mM Na3VO4, 5 mM NaF). Lysate concentration is determined by Beckman Coulter DU 800 spectrophotometer. Lysate is diluted and stored in Storage Buffer (Tris-HCl pH 6.8, 5% glycerol, 1% SDS, 0.002% bromphenol blue, 5% beta-mercaptoethanol). Lysate from ScienCell Research Laboratories is convenient and cost effective for researchers as it eliminates the need to acquire expensive tissues. This product is for research use only. It is not approved for human or animal use, or for application in in vitro diagnostic procedures.
