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.

Protocol Id: 10
AKR1C2 Antibody recognizes endogenous levels of total AKR1C2 protein.Species Reactivity:
Human, Mouse, Rat
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val61 of human AKR1C2 protein. Antibodies are purified by protein A and peptide affinity chromatography.
Aldo-keto reductase family 1 member C2 (AKR1C2) is a member of a large superfamily of aldo-keto reductases that metabolize an array of substrates in a NADPH-dependent manner. AKR1C2 is the 3-α-hydroxysteroid dehydrogenase (3α-HSD) responsible for metabolizing and inactivating the androgen hormone 5α-dihydrotestosterone (DHT) to 3α-androstanediol (1). Research studies demonstrate an increase in AKR1C2 expression in cases of advanced prostate cancer (2). Both AKR1C2 and the related reductase, AKR1C3, are implicated in enhancing PI3K/Akt signaling in prostate cancer by reducing prostaglandin D2 to the more stable 9α, 11β-PGF2α (2). In addition, research studies demonstrate an increase in AKR1C2 expression in some ovarian endometriosis specimens, suggesting the participation of AKR1C2 in the promotion of progesterone metabolism in ovarian endometriosis (3).
