Product Information
Description: 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.
   
Stability and Solubility Advice: Information concerning product stability, particularly in solution, has rarely been reported and in most cases we can only offer a general guide.
We recommend that stock solutions, once prepared, are stored aliquoted in tightly sealed vials and used within 1 month. Avoid repeated freeze and thaw cycles. Storage conditions for some special products should refer to their storage details.
