  • 产品概述

    Caspase 8 (active) FITC Staining Kit (ab65614) provides a convenient means for sensitive detection of activated caspase 8 in living cells. The assay utilizes the caspase 8 inhibitor, IETD-FMK, conjugated to FITC (FITC-IETD-FMK) as a marker. FITC-IETD-FMK is cell permeable, non-toxic, and irreversibly binds to activated caspase 8 in apoptotic cells. The FITC label allows detection of activated caspase-8 in apoptotic cells directly by fluorescence microscopy, flow cytometry, or fluorescence plate reader.

性能

  • 相关性Caspases are cysteine proteases, expressed as inactive precursors, that mediate apoptosis by proteolysis of specific substrates. Caspases have the ability to cleave after aspartic acid residues. There are two classes of caspases involved in apoptosis; initiators (activation by receptor cluster) and effectors (activation by mitochondrial permeability transition). Proapoptotic signals autocatalytically activate initiator caspases, such as Caspase 8 and Caspase 9. Activated initiator caspases then process effector caspases, such as Caspase 3 and Caspase 7, which in turn cause cell collapse.

  • Active caspase 8 in control Jurkat cells (10e6/mL) or cells treated for five hours with 10 ug/mL Cyclohexamide (CHX) (ab120093) or four hours with 25 ug/mL Mitomycin C (MitoC) (ab120797). Background signal subtracted, duplicates; +/- SD.

  • Active caspase 8 in Jurkat cells following four hours exposure to 50 ng/mL anti-Fas Ab (αFas) (MBL), five hours with 10 μg/mL cyclohexamide (CHX) (ab120093), or one hour pretreatment with CHX followed by four hours with αFas. Background signal subtracted, duplicates; +/- SD.

  • Caspase 8 activation of Hela (left) and SiHa (right) cells after in vitro treatment with pentoxylline (PTX) or cisplatin (CIS) either alone or in combination. Results represent the mean ± SD of three independent experiments carried out in triplicate. (*) p<0.001 vs CTL.

Thank you for contacting us. 1.) You may use Caspase-8 negative cells (cells that were not stimulated to induce Caspase-8) for your negative control in Flow Cytometry. 2.) For a viability dye, you may try using PI but this will need to be optimi...
