Bordetella Pertussis FHA IgA ELISA Kit


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


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. It 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. It is common practise to use Bordetella pertussis 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 possesses a large beta-helical which can be both secreted or surface associated, it is also 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.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

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

Your secretory IgA ELISA gave good results and I was also really impressed with how quickly we received it.

It is refreshing to know that you have a technical team that is very knowledgeable. I have already recommended your company to other researchers in our department.

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

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

You are my first point of contact when I am looking to purchase ELISA. You have such an easy and simple system, yet it is very effective.
