Brand Family	Upstate
Trade Name	RIPAb+ Upstate
Description	RIPAb+ PABPC1 - RIP Validated Antibody and Primer Set
Overview	RIPAb+ antibodies are evaluated using the RNA Binding Protein Immunoprecipitation (RIP) assay. Each RIPAb+ antibody set includes quantitative RT-PCR control primers (RIP Primers) to biologically validate your IP results by successfully coprecipitating a specific RNA target (where such a specific target is known). The qPCR protocol and primer sequences are provided, allowing researchers to validate RIP protocols when using the antibody in their experimental context. Each set also includes a negative control antibody to ensure specificity of the RIP reaction. The RIPAb+ PABPC1 set includes the PABPC1 antibody, a negative control antibody (purified mouse IgG), and positive qPCR primers which amplify a 100 bp fragment of the human ACTB cDNA. The PABPC1 and negative control antibodies are supplied in a scalable "per RIP" reaction size and can be used to functionally validate the precipitation of PABPC1-associated RNAs.

Applications
Application	This RIPAb+ PABPC1 -RIP Validated Antibody & Primer Set conveniently includes the antibody & the specific control PCR primers.
Key Applications	RNA Binding Protein Immunoprecipitation (RIP) Immunoprecipitation Western Blotting
Application Notes	Immunoprecipitation from RIP lysate: RIP lysate from HeLa cells (2 X 10⁶ cell equivalents per IP) was subjected to immunoprecipitation using 0.5 μg of either a normal mouse IgG or Anti-PABPC1 antibody. Precipitated proteins were resolved by electrophoresis, transferred to nitrocellulose and probed with anti-PABPC1 (1.0 μg/mL). Proteins were visualized using One-Step™ IP-Western kit (GenScript Cat. # L00232) (Please see figures). Western Blot Analysis: 0.5-2 μg/mL of a previous lot detected PABPC1 in RIPA lysates from HeLa and Jurkat cells (Please see figures). Jurkat cell lysate was resolved by electrophoresis, transferred to nitrocellulose and probed with anti-PABPC1 (0.5 μg/mL). Proteins were visualized using a goat anti-mouse secondary antibody conjugated to HRP and a chemiluminescence detection system.
