Western blot analysis of various cell lines, untreated (-) or treated with Staurosporine #9953 (1 μM; 3 hr) or with Etoposide #2200 (25 μM, overnight), using Caspase-3 (D3R6Y) Rabbit mAb (upper) or β-Actin (D6A8) Rabbit mAb #8457 (lower). MCF7 cells are negative for caspase-3 expression.Learn more about how we get our images.
For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
NOTE: Please refer to primary antibody datasheet or product webpage for recommended antibody dilution.
From sample preparation to detection, the reagents you need for your Western Blot are now in one convenient kit: #12957 Western Blotting Application Solutions Kit
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalent grade water.
Load 20 µl onto SDS-PAGE gel (10 cm x 10 cm).
NOTE: Volumes are for 10 cm x 10 cm (100 cm2) of membrane; for different sized membranes, adjust volumes accordingly.
* Avoid repeated exposure to skin.

Reprobing of an existing membrane is a convenient means to immunoblot for multiple proteins independently when only a limited amount of sample is available. It should be noted that for the best possible results a fresh blot is always recommended. Reprobing can be a valuable method but with each reprobing of a blot there is potential for increased background signal. Additionally, it is recommended that you verify the removal of the first antibody complex prior to reprobing so that signal attributed to binding of the new antibody is not leftover signal from the first immunoblotting experiment. This can be done by re-exposing the blot to ECL reagents and making sure there is no signal prior to adding the next primary antibody.
NOTE: Prepare solutions with reverse osmosis deionized (RODI) or equivalently purified water.

Caspase-3 (D3R6Y) Rabbit mAb recognizes endogenous levels of total caspase-3 protein. This antibody detects full-length caspase-3 as well as the large subunit (p20) of caspase-3 resulting from cleavage during apoptosis.
Human, Mouse, Rat, Monkey
Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the p20 subunit of human caspase-3 protein.
Caspase-3 (CPP-32, Apoptain, 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).
