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.
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.

PPP2R4 (5G3) Mouse mAb recognizes endogenous levels of total PPP2R4 protein. This antibody does not cross-react with other PP2A proteins.
Human, Mouse, Monkey
Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the mouse PPP2R4 protein.
Serine/threonine protein phosphatase 2A regulatory subunit 4 (PPP2R4) is one of the constituents of the regulatory subunit B' of PP2A (1). PPP2R4 is also known as the phosphatase activator (PTPA) and known to have the peptidyl prolyl isomerase (PPIase) activity (2-3). PPIases catalyze cis-trans isomerization of peptide bonds of proline residues in the polypeptide chain; this leads to the rapid folding of proteins (2). The ATPase activity of PPP2R4 is required for the phosphotyrosyl phosphatase activity of PP2A (2-4). Evidence suggests that PPP2R4 induces apoptosis independent of the canonical PP2A-mediated pathways (4).
