Parainfluenza 1/2/3 IgM ELISA Kit

Full Name: Parainfluenza 1/2/3 IgM ELISA Kit
Reactivity: Human
Sample Type: Serum, Plasma
Sensitivity: 1.18 U/ml


Parainfluenza viruses are 15-250 nm in size, negative sense, single stranded RNA that are made up of approx. 15, 000 nucleotides. There are essentially four distinct types which are known as type 1, 2, 3 and 4. All of these have a difference in the severity of the disease but all share antigenic cross-reactivity.

In children some of the most frequent illnesses occur around the upper respiratory tract. Parainfluenza viruses are found to be very closely associated to either veterinary or human diseases. Common procedure that are used routinely to measure this virus include immunofluorescent microscopy, cell culture, PCR and ELISA. The results of the ELISA and HAI methods are comparable.


Human parainfluenza 1/2/3 IgM ELISA kit is designed for analysing in-vitro concentrations of human IgM antibodies against parainfluenza 1/2/3 (parainfluenza-1 IgM, parainfluenza-2 IgM, parainfluenza-3 IgM) with either plasma or serum. This assay has a minimum analytical sensitivity limit of 1.18 U/ml.


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 human IgM antibodies to parainfluenza 1/2/3 (parainfluenza-1 IgM, parainfluenza-2 IgM, parainfluenza-3 IgM) using this parainfluenza-1/2/3 IgM ELISA kit was 1.18 U/ml. The dynamic range for this assay is 1.0 – 200.0 U/ml.

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.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

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.
