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.

PTP4A3 Antibody recognizes endogenous levels of total PTP4A3 protein.
Human, Mouse, Rat
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly62 of human PTP4A3 protein. Antibodies are purified by protein A and peptide affinity chromatography.
The Phosphatase of Regenerating Liver (PRL) family is a distinct group of protein tyrosine phosphatases (PTP), containing a signature phosphatase domain but otherwise lacking homology to known PTP proteins. There are currently three known members of the PRL family (PRL1-3). PRL-1 was the first family member to be identified; it was initially characterized as an immediate early gene (IEG) in regenerating liver and mitogen-treated fibroblasts (1). PRL-3, known widely as PTP4A3, is now the most well-characterized member of the PRL family, due to its important role in regulating cell proliferation, and possibly cancer metastasis. While specific substrates of the PRL-family proteins have remained largely undefined, a recent study in colon cancer cell lines reported that PTP4A3 dephosphorylated integrin β1 at Tyr783 (2). PTP4A3 was also shown to play a potential role in the progression of cardiac hypertrophy by inhibiting tyrosine phosphorylation of the docking protein p130 (3). Increased rates of both cell proliferation and motility have been observed in immortalized cell lines and murine lung tumor cells over-expressing PTP4A3 (3,4), and elevated levels of PTP4A3 protein are associated with a subset of human cancers (5,6).
