Full Methods

Primary Antibody: ABIN7251291

Secondary Antibody: anti-rabbit Alexa Fluor 488 (Invitrogen. Lot 2541675)

Full Protocol:

• Sample analyzed: mouse brain at post-natal day (P) 5-6
• Paraffin-embedded slices (7 µm thick) were deparaffinized and rehydrated through a graded series of alcohols and distilled water (dH2O).
• Sections were blocked in ovalbumin 1% 1 hour at room temperature
• Antigen retrieval was performed in all the sections by microwave treatment (1 minute at 750W + 1 minute at 250W in Citrate buffer pH 6)
• 3x5 minutes washing in 0.01M PBS
• Sections were incubated with the primary antibody at the following dilutions of 1:50/1:100/1:200, overnight at room temperature (primary antibody was diluted in PLL/BSA/PBS diluent)
• 3x5 minutes washing in 0.01M PBS
• Incubation with the anti-rabbit secondary antibody 1:400 in PLL/BSA/PBS diluent, 1 hour at room temperature.
• 3x5 minutes washing in 0.01M PBS
• Nuclear counterstaining was performed with DAPI 1µg/mL, 2 minutes
• 2x5 minutes washing in 0.01M PBS
• Specimens were then mounted in Fluoroshield mounting medium (Sigma)

Experimental Notes:

The antibody works in IHC-P at concentrations from 1:50-1:200.

Target Details

Target: Caspase 3 p12

Alternative Name: CASP3 p12

Background: Involved in the activation cascade of caspases responsible for apoptosis execution. At the onset of apoptosis it proteolytically cleaves poly(ADP-ribose) polymerase (PARP) at a '216-Asp-Gly-217' bond. Cleaves and activates sterol regulatory element binding proteins (SREBPs) between the basic helix-loop-helix leucine zipper domain and the membrane attachment domain. Cleaves and activates caspase-6, -7 and -9. Involved in the cleavage of huntingtin.
