Specificity
Mouse, Rat: We have preliminary internal testing data to indicate this antibody may not react with these species. Please contact us for more information This antibody only detects the active (cleaved) form of Caspase-3 and does not recognize the pro form of Caspase-3. PubMedID 19789217 describes the detection of human cells injected into mice. The pro-caspase-3 is cleaved only when apoptosis event occurs. So, in order to detect active Caspase-3, we strongly suggest to induce your samples into apoptotic pathway. -

Lanes 1 - 6: Merged signal (red and green). Green - ab32042 observed at 17 kDa. Red - loading control, ab130007, observed at 130 kDa.ab32042 was shown to specifically react with CASP3 (Caspase-3) when CASP3 (Caspase-3) knockout samples were used. HAP1 wild-type and CASP3 (Caspase-3) knockout samples were subjected to SDS-PAGE. Ab32042 and ab130007 (Mouse anti vinculin loading control) were incubated overnight at 4°C at 500 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/10000 dilution for 1 hour at room temperature before imaging.
Cells were grown to confluency prior to treatment.

High-glucose induces apoptosis in human Vascular endothelial cells (VECs).
Apoptotic responses in VEC were analyzed by detection of cleaved-Caspase-3 immunofluorescence using ab32042. Cells were treated with low glucose (LG) or high glucose (HG) for 72 hours before treated with 100 ng/mL bFGF, 1 μM sp600125 (sp), or 1 μM U0126 (U) or 10 μM MnTmPyP for 1 hour. Bar = 100 μm.
