| Description | RIPAb+ HuR - 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+ HuR set includes the HuR antibody, a negative control antibody (purified Rabbit IgG), and positive qPCR primers which amplify a 100 bp fragment of the human beta actin (ACTB) cDNA. The HuR and negative control antibodies are supplied in a scalable "per RIP" reaction size and can be used to functionally validate the precipitation HuR-associated RNAs. |

| Key Applications |
|
| Application Notes | Immunoprecipitation from RIP lysate: RIP lysate from MCF7 cells (2 X 106 cell equivalents per IP) was subjected to immunoprecipitation using 0.5 μg of either a normal rabbit IgG or Anti-HuR antibody. Precipitated proteins were resolved by electrophoresis, transferred to nitrocellulose and probed with anti-HuR (1.0 μg/mL). Proteins were visualized using One-Step™ IP-Western kit (GenScript Cat. # L00231) (Please see figures). Western Blot Analysis: 3T3/A31 lysate was resolved by electrophoresis, transferred to PVDF membranes and probed with HuR, hu (1:500 dilution). Proteins were visualized using a Donkey anti-Rabbit conjugated to HRP and visualized using a chemiluminescence detection system. (Please see figures). Immunoprecipitation Analysis: 10 ug of this antibody immunoprecipitated HuR from 500 ug of 3T3/A31 RIPA lysate (Please see figures). mmunocytochemistry Analysis: Confocal IF analysis of HeLa, NIH/3T3 using anti-HuR (Red). Actin filaments have been labeled with AlexaFluor® 488 -Phalloidin (Green). Nucleus is stained with DAPI (Blue) (Please see figures). |
