Bordetella Pertussis FHA IgA ELISA Kit

  • Created on the 12 July, 2017.

BACKGROUND

Bordetella pertussis is a pathogenic, gram-negative bacteria which belongs to the genus Bordetella family and is the causative agent of whooping cough or pertussis. The virulence factors of B. pertussis include filamentous haemagglutinin (FHA), pertussis toxin, tracheal cytotoxin, pertactin and fimbria. FHA is a cell surface protein that plays a major role in adhesin for this organism and it forms an essential component of a large number of new acellular pertussis vaccines. In is common practise to use FHA in combination with pertussis toxin for many diagnostic screening applications, whereas the use of highly pure B. pertussis toxin alone is used mainly monitoring of vaccination programmes. FHA is a highly immunogenic and large beta-helical which can be both secreted or surface associated. FHA is able to display a variety of attachment activities which is largely derived from its multiple binding domains. This property is able to facilitate Bordetella attachment to many extracellular structures and eukaryotic cell types.

INTENDED USE

Human Bordetella pertussis FHA-IgA ELISA kit can be used for analysing in-vitro quantitative amounts of human IgA antibodies against Bordetella FHA using plasma and serum samples. This assay has a minimum analytical sensitivity limit of 0.5 IU/ml.

SENSITIVITY

The minimum detection sensitivity level of human Bordetella FHA IgA using this human Bordetella pertussis FHA-IgA ELISA kit was 0.5 IU/ml. The dynamic assay range for this kit is 10.0 – 50.0 IU/ml.

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA kit performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA kits from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
