4335-MC-100 Anti-PAR Polymer Monoclonal Antibody100 µl$260.00

This monoclonal antibody is specific for poly(ADP-ribose) (PAR) polymer. It can be used to detect ribosylated proteins by ELISA, Western blot, immunocytochemistry in situ, and for immunopurification. It is supplied with a positive control for ELISA and Western blot analysis consisting of poly-ADP-ribosylated PARP-1 protein (PARP-PAR).


  • ELISA, Western Blot Analysis, immunoprecipitation, and immunopurification. For Western blots, an antibody dilution of 1:1000 is recommended. 


  • Store the anti-PAR monoclonal at -20°C (manual defrost freezer). 
  • Store the PARP-treated protein control at -80°C.


This antibody is an IgG3 and is provided as purified immunoglobulin from mouse ascites in1X PBS containing 50% glycerol at 1 mg/ml. PARP-PAR is provided at 75 μM in 10 mil Tris-HCl (pH 8.0), 1 mM EDTA.


Purified ADP-ribose polymers between 2 and 50 units long


The antibody is specific for PAR polymers 2 to 50 units long, but does not recognize structurally related RNA, DNA, ADP-ribose monomers, NAD+, or other nucleic acid monomers.
