Specificity:

Mouse Anti-Human Caspase-3 Active Subunit (p17) (CASP3) (Clone C31.129) recognizes an epitope on Human CASP3. This monoclonal antibody was purified using multi-step affinity chromatography methods such as Protein A or G depending on the species and isotype.

Background:

Caspase-3 is a member of the caspase family of cysteine proteases and plays a key role in mediating Fas (CD95) and tumor necrosis factor–1 (TNFR-1) induced apoptosis. Caspases can be divided into three groups: apoptotic initiators, apoptotic executioners, and inflammatory mediators.^1,2 Caspase-3 is activated during apoptotic signaling events by upstream proteases including caspase 6 and caspase 8.³ Caspase-3 is thought to be essential for chromatin margination, DNA fragmentation and nuclear collapse during apoptosis.³

DyLight® 550 conjugated antibodies absorb light maximally around 562 (± 4 nm) and fluoresce with a peak around 576 nm. They are brighter than TRITC conjugates, and they are equal in brightness to Cy3 and Alexa Fluor 555. All Dylight® 550 antibodies are recommended for maximum sensitivity in all immunofluorescence detection procedures within the orange-red portion of the visible spectrum.
