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).

General description

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. The Ago family consists of two subclases, Ago and Piwi containing two characteristic domains known as PAZ and PIWI. These two domains interact with different parts of the mature miRNA. The PAZ domain interacts with the 3’-end of the miRNA, and the PIWI domain interacts with the 5’ phosphate and 5’-proximal region of the miRNA to guide target mRNA recognition.

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.

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.
