| Bioactivity | TPCK (L-1-Tosylamido-2-phenylethyl chloromethyl ketone; L-TPCK) is a potent serine protease inhibitor that reacts with the retinoblastoma protein (RB)-binding core of HPV-18 E7 protein and abolish its RB-binding capability. TPCK is able to modify E7 protein in live keratinocytes following its addition to the culture medium[1]. | ||||||||||||
