    Figure 1. Immunoprecipitation of endogenous Argonaute proteins using the Diagenode Ago monoclonal antibody
    Hela cells (10 cm dish per IP) were subjected to UV crosslinking, lysed in 70 μl of 1xPXL buffer (1xPBS, 0.1% SDS, 0.5% Nadeoxycholate, 0.5% NP-40) by incubating on ice for 10 min, then treated with DNase I. Dynabeads Protein A (40 μl each) were first incubated with 12 μg anti-mouse IgG, used as a bridge antibody, briefly washed, and then incubated with Diagenode Ago monoclonal antibody (Cat. No. C15200167) (4 or 12 μg), or non-immune mouse IgG control (4 or 12 μg). The cell lysate and Dynabeads were mixed and incubated at 4°C for overnight. The beads were washed twice each at 4°C for 5 min using 500 μl of (i) 1 x PXL buffer, (ii) 5 x PXL (5xPBS, 0.1% SDS, 0.5% Na-deoxycholate, 0.5% NP-40), and (iii) 1 x PNK (50 mM Tris pH7.4, 10 mM MgCl2, 0.5% NP-40). Ten μl of input (10% of starting material), 10 μl of supernatants after immunoprecipitation (10%), and all of immunoprecipitants (~90%) were loaded on SDS-PAGE gel and subjected to western blot analysis using the Diagenode Ago monoclonal antibody (Cat. No. C15200167) and the ECL plus reagent.


    Figure 2. Allelic imbalance Ago-RIP assay with the Diagenode Argonautes monoclonal antibody
    The goal of this experiment is to show the preferential coimmunoprecipitation of the miRNA targeted alleles using Diagenode Ago monoclonal antibody (Cat No. C15200167). Briefly, Hela cells were transfected with: pRL-TK-4A + pRL-TK-4G + pcDNA-miR-1 (miR-1 is supposed to target “A” allele) pRL-TK-4A + pRL-TK-4G + pcDNA-miR-1C (miR-1C is supposed to target “G” allele) pRL-TK-4A + pRL-TK-4G + pcDNA-miR-377 (miR-377 is supposed to target neither allele) Cell lysate was immunoprecipitated with Protein G agarose beads incubated with Diagenode Ago monoclonal antibody. RNA was isolated from the complexes from the input and IP samples, reverse transcribed using random hexamers, and subjected to RT-PCR to confirm enrichment of miRNA targeted allele in IP sample compared to input sample. The PCR products were directly sequenced. The electropherograms at the polymorphic site are shown in the second panel. “The predicted miRNA target alleles were efficiently coimmunoprecipitated by the Diagenode Ago monoclonal antibody (Cat. No. C15200167). More details can be found in Takeda H, Charlier C, Farnir F, Georges M., RNA, 2010,1854-63, Epub 2010, Aug 2. Results were kindly provided by Haruko Takeda (Unit of Animal Genomics, GIGA Research Center, Faculty of Veterinary Medicine, University of Liège, 4000-Liège, Belgium).


    Figure 3. Western blot analysis using the Diagenode Ago monoclonal antibody
    Whole cell extracts (40 µg) from HeLa cells were analysed by Western blot using the Diagenode Ago monoclonal antibody (Cat. No. C15200167) diluted 1:500 in TBS-Tween containing 5% skimmed milk. The position of the protein of interest is indicated on the right; the marker (in kDa) is shown on the left.


    Figure 4. Immunofluorescence using the Diagenode Ago monoclonal antibody
    HeLa cells were stained with the Diagenode antibody against Ago (cat. No. C15200167) and with DAPI. Cells were fixed with 4% formaldehyde for 10’ and blocked with PBS/TX-100 containing 1% BSA. The cells were immunofluorescently labelled with the Ago antibody (middle) diluted 1:500 in blocking solution followed by an anti-mouse antibody conjugated to Alexa594. The left panel shows staining of the nuclei with DAPI. A merge of both stainings is shown on the right.

    ACE-score-based Analysis of Temporal miRNA Targetomes During Human Cytomegalovirus Infection Using AGO-CLIP-seq
    Kim S et al.
    Although temporal regulation of gene expression during the course of infection is known to be critical for determining the outcome of host-virus interactions, systematic temporal analysis of the miRNA targetomes during productive viral infection has been technically challenging due to the large range of miRNA-mRNA c...

    Differential RISC association of endogenous human microRNAs predicts their inhibitory potential.
    Flores O, Kennedy EM, Skalsky RL, Cullen BR
    It has previously been assumed that the generally high stability of microRNAs (miRNAs) reflects their tight association with Argonaute (Ago) proteins, essential components of the RNA-induced silencing complex (RISC). However, recent data have suggested that the majority of mature miRNAs are not, in fact, Ago associa...
