Mechercharmycin A is a cyclic peptide originally isolated from Thermoactinomyces that has anticancer activity. It induces cytotoxicity in A549 lung cancer and Jurkat leukemia cells (IC50s = 40 and 46 nM, respectively).Formal Name:...

NucView(R) 488 Caspase-3 Substrate is a novel cell membrane-permeable fluorogenic caspase substrate designed for detecting caspase-3/7 activity within live cells in real time. Unlike conventional caspase assays, NucView(R) 488 Caspase-3 Substrate detects caspase-3/7 activity within individual intact cells without...

NucView(R) 488 Caspase-3 Substrate is a novel fluorogenic caspase substrate for real-time detection of caspase-3/7 activity in live cells. In apoptotic cells, the substrate is cleaved to release a DNA dye that stains the nucleus with bright green fluorescence. 1 mM in PBS, 100 uL.

Ac-DEVD-CHO is a synthetic tetrapeptide competitive inhibitor for Caspase-3/7, and contains the amino acid sequence of the PARP cleavage site. Ac-DEVD-CHO can be used to inhibit Caspase-3/7 activity in apoptotic cells, and to study events downstream of Caspase-3/7 activation.Soluble in DMSOStore at 4°CC20H30N4O11MW:...

NucView(R) 405 Caspase-3 Substrate, 1 mM in DMSO, provides a convenient tool for detecting apoptosis in intact cells based on caspase-3/7 activity using either confocal microscopy or flow cytometry.
