Abcam's anti-Bordetella pertussis toxin (PT) IgG
in vitro
ELISA (Enzyme-Linked Immunosorbent Assay) kit is designed for the accurate quantitative measurement of IgG class antibodies to Bordetella pertussis toxin (PT) in Human serum and plasma (citrate).
A 96-well plate has been precoated with Bordetella pertussis toxin to bind cognate antibodies. Controls or test samples are added to the wells and incubated. Following washing, a horseradish peroxidase (HRP) labelled anti-Human IgG conjugate is added to the wells, which binds to the immobilized B. pertussis toxin-specific antibodies. TMB is then catalyzed by the HRP to produce a blue color product that changes to yellow after adding an acidic stop solution. The intensity of yellow coloration is directly proportional to the amount of Helicobacter pylori IgG sample captured in plate.

Bordetella pertussis IgG commonly referred to as pertussis IgG is an immunoglobulin that targets the Bordetella pertussis bacterium the causative agent of whooping cough. This IgG specifically binds to the Bordetella pertussis toxin neutralizing its effects and helping prevent colonization and infection in the respiratory tract. Immunoglobulin G (IgG) is a major antibody type in the body's immune response and is found expressed in blood interstitial fluid and tissues throughout the body. Bordetella pertussis toxin a protein with a molecular mass of approximately 105 kDa plays a significant role in the pathogen's virulence.
Biological function summary
The function of Bordetella pertussis IgG involves the human adaptive immune response where it aids in recognizing and neutralizing foreign pathogens like pertussis toxin. This IgG antibody does not form part of a larger complex itself but plays a critical role in the collective immune strategy. By binding with high affinity to the pertussis toxin the antibody blocks its interaction with host cells a step integral for the toxin’s ability to interfere with cellular processes and harm the host.
Pathways
Several components including Bordetella pertussis IgG play a role in the immune recognition and response pathways specifically the humoral immune response. This antibody works in conjunction with other immune proteins like memory B cells and helper T cells which aid in generating a stronger response upon future exposure to the pathogen. The action of Bordetella pertussis IgG is essential in the adaptive immune pathway reinforcing the overall defense mechanism against such bacterial pathogens.
Bordetella pertussis IgG is most closely associated with whooping cough a highly contagious respiratory disease. The presence and levels of this IgG indicate immunity level against the disease whether from vaccination or past infection. Furthermore insufficient levels of this antibody can leave individuals susceptible to Bordetella pertussis infections. Pertussis toxin and its antibody Bordetella pertussis IgG serve as key components in diagnostics and understanding the disease's clinical progression and immune evasion strategies.
