Product Information

Product Usage Information

CST recommends transfection with 100 nM Caspase-3 siRNA. Decreased Caspase-3 expression was observed 24-72 hours post-transfection. See Protocol for transfection procedure.

Each vial contains the equivalent of 100 transfections, which corresponds to a final siRNA concentration of 100 nM per transfection in a 24-well plate with a total volume of 300 μl per well.

Storage

SignalSilence^® siRNA is supplied in RNAse-free water. Aliquot and store at -20ºC.

Specificity / Sensitivity

Species Reactivity:

Human

Product Description

SignalSilence^® Caspase-3 siRNA allows the researcher to specifically inhibit Caspase-3 expression using RNA interference, a method in which gene expression can be selectively silenced through the delivery of double stranded RNA molecules into the cell. All SignalSilence^® siRNA products from CST are rigorously tested in-house and have been shown to reduce protein expression in specified cell lines.

Background

Caspase-3 (CPP-32, Apopain, Yama, SCA-1) is a critical executioner of apoptosis, as it is either partially or totally responsible for the proteolytic cleavage of many key proteins, such as the nuclear enzyme poly (ADP-ribose) polymerase (PARP) (1). Activation of caspase-3 requires proteolytic processing of its inactive zymogen into activated p17 and p12 fragments. Cleavage of caspase-3 requires the aspartic acid residue at the P1 position (2).

In addition to its central role in apoptosis, Caspase-3 has been shown to play a role in erythroid differentiation through the use of RNA interference (3).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).
