      DescriptionRIPAb+™ Ago3 Antibody
      OverviewRIPAb+ antibodies are evaluated using the RNA Binding Protein Immunoprecipitation (RIP) assay. Each RIPAb+ antibody set includes a negative control antibody to ensure specificity of the RIP reaction and is verified for the co-immunoprecipitation of RNA associated specifically with the immunoprecipitated RNA-binding protein of interest. Where appropriate, the RIPAb+ set also includes quantitative RT-PCR control primers (RIP Primers) to biologically validate your IP results by successfully co-precipitating the specific RNA targets, such as messenger RNAs. The qPCR protocol and primer sequences are provided, allowing researchers to validate RIP protocols when using the antibody in their experimental context. If a target specific assay is not provided, the RIPAb+ kit is validated using an automated microfluidics-based assay by enrichment of detectable RNA over control immunoprecipitation.
      Ago3 (Eukaryotic translation initiation factor 2C 3) belongs to the argonaute family and contains a PAZ and a Piwi domain. Ago3 plays a role in the RNA interference (RNAi) pathway, which is important for heterochromatin formation and accurate chromosome segregation.

      Background InformationEukaryotic translation initiation factor 2C 3, Ago3, belongs to the argonaute family and contains 1 PAZ and 1 Piwi domain.
      Ago3 is indicated to play a role in the RNA interference (RNAi) pathway, which is important for heterochromatin formation and accurate chromosome segregation. Unlike Ago1 and Ago2, Ago3 and AG04 do not possess the ability to dissociate miRNA duplexes in a minimal in vitro system. Re-introduction of any Ago variant into embyronic (ES) cells deficient for expression of all four Ago variants will rescue miRNA silencing defects and reduce apoptosis.

      Application NotesRNA Binding Protein Immunoprecipitation (microRNA):

      Representative lot data.
      RIP Lysate prepared from 293 cells (2 X 107 cell equivalents per IP) were subjected to immunoprecipitation using 5 µg of either a normal mouse IgG (Cat. # CS200621), or Anti-Ago 3 antibody (Cat. # CS207366) and the Magna RIP™ RNA-Binding Protein Immunoprecipitation Kit (Cat. # 17-700).
      Successful immunoprecipitation of Ago 3-associated microRNA was verified by TaqMan® microRNA assay, hsa-miR-15a. (Figure2). Please refer to the Magna RIP™ (Cat. # 17-700) or EZ-Magna RIP™ (Cat. # 17-701) protocol for experimental details.
      Immunocytochemistry Analysis:
      Representative lot data.
      Confocal fluorescent analysis of HeLa cells using Anti-Ago3, clone 4B1-F6 (Red). Actin filaments have been labeled with Alexa Fluor® 488 dye-Phalloidin (Green). Nucleus is stained with DAPI (Blue). This antibody positively stains the cytoplasm.

      Entrez Gene Number
      Entrez Gene SummaryThis gene encodes a member of the Argonaute family of proteins which play a role in RNA interference. The encoded protein is highly basic, contains a PAZ domain and a PIWI domain, and may play a role in short-interfering-RNA-mediated gene silencing. This gene is located on chromosome 1 in a tandem cluster of closely related family members including argonaute 4 and eukaryotic translation initiation factor 2C, 1. Two transcript variants encoding distinct isoforms have been identified for this gene.
