Description

PARP1 antibody

Images & Validation

• Tested Applications: 2D-PAGE, WB
• Dilution Range: WB: 1:1000
• Reactivity: Human
• Application Notes:
  Anti-PARP1 (internal) antibody has been tested by western blotting and nanoimmunoassay (NIA). Specific conditions for reactivity should be optimized by the end user. Expect a band approximately 113 kDa in size corresponding to PARP-1 by western blotting in the appropriate cell lysate or extract.

Key Properties

• Antibody Type: Primary Antibody
• Host: Rabbit
• Clonality: Polyclonal
• Isotype: IgG
• Immunogen: PARP1 (internal) purified antibody was prepared from whole rabbit serum produced by repeated immunizations with c-terminus region of human PARP1 autocatalytic domain recombinant protein.
• Target: PARP1
• Purity: PARP1 (internal) was purified from monospecific antiserum by immunoaffinity chromatography using protein A coupled to agarose beads. This antibody is specific for human PARP1 protein. No cross reactivity detected towards other PARP members when using siRNAs against 18 PARP family members. Cross-reactivity with PARP1 from other sources has not been determined.
• Conjugation: Unconjugated
