설명

애플리케이션

Nα-Tosyl-L-lysine chloromethyl ketone hydrochloride has been used:

• in chymotrypsin purification to prevent binding of trypsins to the affinity support by inhibiting them in the crude extract
• as a protease inhibitor in tissue and cell homogenization
• as a trypsin inhibitor to determine the specific protease activity levels

생화학적/생리학적 작용

Nα-Tosyl-L-lysine chloromethyl ketone hydrochloride (TLCK) blocks the lipopolysaccharide (LPS)- or cytokine-induced activation of nuclear factor κB (NF-κB), which, in turn, blocks the induction of inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) transcription. Blocks activation of pp70s6k by all mitogens. Blocks apoptosis in cell lines by inhibiting the processing of caspases in some cell lines and to some stimuli.
