RIPAb+ Ago3 Antibody

32160702

NA.32

RIPAb+ 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.

This antibody has been shown to not cross react with Ago1, Ago2, or Ago4 (Azuma-Mukai A et al. (2008) Proc. Natl. Acad. Sci. USA 105: 7964-7969).

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.

Stable for 1 year at -20°C from date of receipt. Handling Recommendations: Upon first thaw, and prior to removing the cap, centrifuge the vial and gently mix the solution. Aliquot into microcentrifuge tubes and store at -20°C. Avoid repeated freeze/thaw cycles, which may damage IgG and affect product performance.
Note: Variability in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.
