Anti-Adenylate Cyclase Toxin [9D4] Antibody
This IgG2a mouse antibody was generated against Bordetella pertussis Adenylate Cyclase toxin and recognizes an epitope in the glycine and aspartate-rich nonapeptide repeat region (amino acids 1156-1489) of B. pertussis and other repeats-in-toxin (RTX) family bacteria toxins.
Highlights:
- Reacts with adenylate cyclase
- Suitable for Western Blot and Immunoprecipitation applications
Recombinant versions available from our sister company, Absolute Antibody:
- Manufactured using Absolute Antibody’s Recombinant Platform with variable regions (i.e., specificity) from the hybridoma 9D4.
Adenylate Cyclase Toxin (ACT or Cya A) is one of several virulence factors produced by the bacterium Bordetella pertussis. This toxin invades eukaryotic cells and catalyzes the conversion of ATP into cyclic AMP (cAMP). This leads to inhibition of host cell immune function and macrophage death by apoptosis. The Adenylate Cyclase protein is composed of a catalytic domain (amino acids 1 to 400), a hydrophobic region (amino acids 500 to 700), a glycine/aspartate-rich repeat unit (amino acids 1000 to 1600), and the C-terminal domain (amino acids 1600-1706).

Monoclonal antibody that immunoprecipitates AC enzyme activity recognize a 216-kDaprotein by Western blot.
(A) Sucrose gradient pool (210 pg/ml) was separated by 12.5% SDS-PAGE, transferred onto a PVDF membrane, and incubated with 9D4 monoclonal antibody. (B) Urea extracts (25 pg each) of BP338, wild type strain (lower A), and two Tn5 mutants, BP348 (lane B) and RP347 (laneC), both lacking AC, were fractionated by 12.5% SDS-PAGE, transferred to PVDF, and incubated with monoclonal antibody 9D4.
