Application

Western Blot Analysis:
Representative lot data.
HeLa cell lysate was probed with Anti-pan Ago, clone 2A8 (0.5 µg/mL). Proteins were visualized using a Goat Anti-Mouse IgG secondary antibody conjugated to HRP and chemiluminescence detection system.
Arrows indicates Ago (~ 95 kDa) and Radixin (~70 kDa). (Figure 2).

General description

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.
Argonaute (Ago) proteins are a family of proteins of ~95 kDa that bind directly to mature miRNAs. In mammals, there are four Ago proteins (Ago1-4). This family of proteins is a central component of most mammalian miRNPs that mediates important functions in small RNA-directed regulatory pathways.

Immunogen

Histidine - tagged recombinant protein corresponding to human Ago.

Quality

RNA Binding Protein Immunoprecipitation:
Representative lot data.
RIP Lysate prepared from 293 cells (2 X 10E7 cell equivalents per IP) were subjected to immunoprecipitation using 5 µg of either a normal mouse IgG or 5 µg of Anti-pan Ago antibodyand the Magna RIP^® RNA-Binding Protein Immunoprecipitation Kit (Cat. # 17-700).
Successful immunoprecipitation of Argonaute proteins-associated RNA was verified by qPCR using RIP Primers IGF2, (Figure 1).
Please refer to the Magna RIP™ (Cat. # 17-700) or EZ-Magna RIP™ (Cat. # 17-701) protocol for experimental details.

Specificity

This antibody recognizes Ago1, Ago2, Ago3, and Ago4. Note that this antibody has been reported to cross-react with radixin (~70 kDa). (Nelson, P., et al. (2007). RNA. 13:1787–1792.)

Storage and Stability

Stable for 1 year at -20°C from date of receipt.
Handling Recommendations: Upon receipt, 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: Variabillity in freezer temperatures below -20°C may cause glycerol containing solutions to become frozen during storage.
