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.

HTATIP2/TIP30 Antibody recognizes endogenous levels of total HTATIP2 protein.Species Reactivity:
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding His231 of human HTATIP2 protein. Antibodies are purified by protein A and peptide affinity chromatography.
The HIV-1 Tat interactive protein 2 (HTATIP2, TIP30, CC3) is an oxidoreductase that was originally identified as a metastatic tumor suppressor and Tat-mediated proapoptotic gene transcription cofactor (1,2). HTATIP2 protein contains a short-chain dehydrogenase (SDR) domain and a NADPH binding motif important for HTATIP2 interaction with importins and inhibition of nucleocytoplasmic transport (3,4). Research studies demonstrate that induced overexpression of HTATIP2 predisposes cells to apoptosis by inhibiting the nuclear transport of important signaling proteins (e.g. p53, activated notch1) and several key targets of the DNA repair process (5-7). HTATIP2 is part of a protein complex, with Rab5a, endophilin B1, and ACSL4, that may regulate EGFR receptor endosomal trafficking, degradation, and cytoplasmic/nuclear signaling (8,9). Silencing of HTATIP2 promotes tumor cell survival under low glucose conditions by inducing increased expression of mitochondrial respiratory proteins and glucose metabolic enzymes (10).
