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.

Paip2A Antibody detects endogenous levels of total Paip2A protein.
Human, Mouse, Rat, Monkey
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to human Paip2A. Antibodies are purified by protein A and peptide affinity chromatography.
The eukaryotic mRNA 3' poly(A) tail interacts with the 5' cap structure to regulate translation of mRNA transcripts (1). The eIF4G translation initiation factor associates with poly(A) binding protein (PABP) to circularize mRNA (1,2). Paip1 is a PABP interacting protein that binds eIF4A to stimulate translation (3). A second PABP binding protein, Paip2, inhibits translation by interfering with PABP function. Specifically, Paip2 reduces the affinity of PABP for poly(A) RNA and competes with Paip1 for PABP binding (1,2).
