ZooMAb antibodies represent an entirely new generation of recombinant monoclonal antibodies.

Each ZooMAb antibody is manufactured using our proprietary recombinant expression system, purified to homogeneity, and precisely dispensed to produce robust and highly reproducible lot-to-lot consistency. Only top-performing clones are released for use by researchers. Each antibody is validated for high specificity and affinity across multiple applications, including its most commonly used application. ZooMAb antibodies are reliably available and ready to ship when you need them.

Specificity

Clone 2A8 is a ZooMAb® mouse recombinant monoclonal antibody that detects all isoforms of human Argonaute-2 protein.

Immunogen

His-tagged recombinant fragment corresponding to 813 amino acids from human Argonaute-2 protein.

Note: Actual optimal working dilutions must be determined by end user as specimens, and experimental conditions may vary with the end user
Anti-pan Ago, clone 2A8 ZooMAb®, Cat. No. ZMS1071, is a recombinant Mouse monoclonal antibody that targets Ago protein and is used in Flow Cytometry, Immunocytochemistry, Immunohistochemistry (Paraffin), Immunoprecipitation, and Western Blotting.

Target description

Protein argonaute-2 (UniProt: Q9UKV8; also known as Argonaute2, hAgo2, Argonaute RISC catalytic component 2, Eukaryotic translation initiation factor 2C, eIF-2C, eIF2C, PAZ Piwi domain protein, PPD, Protein slicer) is encoded by the AGO2 (also known as EIF2C2) gene (Gene ID: 27161) in human. Ago2 is a highly conserved member of the AGO family of proteins with catalytic activity and is required for RNA-mediated gene silencing (RNAi) by the RNA-induced silencing complex (RISC). Binding of RISC to a perfectly complementary mRNA generally results in silencing due to endonucleolytic cleavage of the mRNA specifically by Ago2. Binding of RISC to a partially complementary mRNA results in silencing through inhibition of translation and is independent of endonuclease activity. Ago2 is reported to inhibit translation initiation by binding to the 7-methylguanosine cap, thereby preventing the recruitment of the translation initiation factor eIF4-E. The inhibition of translational initiation leads to the accumulation of the affected mRNA in cytoplasmic processing bodies (P-bodies), where mRNA degradation may subsequently occur. Ago2 is shown to have four core domains that are known as N domain, PAZ domain (aa 235-348), MID domain, and PIWI domain (aa 517-818). The PAZ domain is an RNA binding module that recognizes the 3 end of both siRNA and miRNA, in a sequence independent manner and is reported to be strictly required for Ago2 to form the RISC complex. The PIWI domain has major roles within Ago2, including RNase H like endonucleolytic activity and regulating the interaction between MID domain and DNA/RNA. Ago2 is shown to undergo 4-hydoxylation that enhances its stability but is not essential for miRNA binding or endonuclease activity. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals. (Ref.: Ye, Z., et al. (2015). J. Cancer 6(9); 877-882).

Physical form

Purified recombinant mouse monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.

Reconstitution

300 μg/mL after reconstitution at 25 μL per vial. Please refer to guidance on suggested starting dilutions and/or titers per application and sample type.

Storage and Stability

Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
