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.

PTBP1 Antibody recognizes endogenous levels of total PTBP1 protein.
Human, Mouse, Rat, Monkey
Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to the human PTBP1 protein. Antibodies are purified by protein A and peptide affinity chromatography.
PTBP1/hnRNP I belongs to the family of heterogeneous nuclear ribonucleoproteins (hnRNPs) that exert diverse functions in multiple aspects of RNA metabolism (1). PTBP1 is critical for regulating alternative splicing, IRES-mediated translation initiation, and increased stability of a variety of transcripts (2-4). Recently, PTBP1 was found to interact with PSMA3 from the 20S proteasome and is therefore implicated in the process of protein degradation (5,6). PTBP1 is ubiquitously expressed and shuttles between the nucleus and cytoplasm. Cellular localization of PTBP1 and its interactions with various factors determines the diversity of PTBP1 function (4).
