While not specifically listed as a '100X' concentration, a volume of 1 ml of this solution is sufficient for 100ml of cell lysate. However, this is based on the mass and origin of the lysate preparation. The 100 mL of cell lysate referenced is prepared from 20 g of E. coli cells or 10 g of baculovirus-infected cells.
