Anti-pan-ADP-ribose binding reagent

Cat. No.MABE1016, Anti-pan-ADP-ribose binding reagent, is a His-tagged recombinant protein fused to rabbit Fc tag, expressed in and purified from Rosetta(DE3)pLysS strain of E. coli (Cat. No. 70956). Anti-pan-ADP-ribose binding reagent is useful for the affinity detection of both mono- and poly-ADP-ribosylated proteins on membranes in a manner similar to antibody-based Western and dot blot analysis, The rabbit Fc tag allows visualization of the binding with conjugated anti-rabbit secondary antibodies. The Fc tag also allows Anti-pan-ADP-ribose binding reagent to be captured on Protein A resins for affinity pull-down applications.

Variable depending on the target proteins and the extend of ADP-ribosylation.

Anti-poly-ADP-ribose binding reagent is a reagent that selectively binds to both mono- and poly- ADP ribose for use in Western Blotting, Immunocytochemistry and Dot Blot.

Dot Blot Specificity Analysis: This reagent detected mono(ADPR) on recombinant PARP3 protein, as well as mono(ADPR) and poly(ADPR) on recombinant PARP1 recombinant protein (Lee Kraus, University of Texas Southwestern Medical Center).

Immunoprecipitation Analysis: A representative lot of Anti-pan-ADP-ribose binding reagent immunoprecipitated ADP-ribosylated proteins from nuclear extract (Lee Kraus, University of Texas Southwestern).

Western Blotting Analysis: A representative lot detected auto-ADP-ribosylation activity of PARP1/2/3 and mutants in the presence of NAD+ or various NAD+ analogs (Gibson, B.A., et al. (2016). Science. 353(6294):45-50).

Western Blotting Analysis: A representative lot detected PARP1-catalyzed NELF-E ADP-ribosylation in cell-free enzymatic reactions as well as ADP-ribosylation of exogenously expressed FLAG-tagged NELF-E in HEK293T cells. PARP inhibitor PJ34 or P-TEFb/CDK9 inhibitor flavopiridol treatment decreased cellular NELF-E ADP-ribosylation level (Gibson, B.A., et al. (2016). Science. 353(6294):45-50).
