Parainfluenza 1/2/3 IgG ELISA Kit

Full Name: Parainfluenza 1/2/3 IgG ELISA Kit
Reactivity: Human
Sample Type: Serum, Plasma
Sensitivity: 1.04 U/ml


There are presently four distinct types of parainfluenza viruses namely type 1, 2, 3 and 4. These are all single stranded, negative sense RNA which are 15-250 nm in size and made up of about 15, 000 nucleotides. They share antigenic cross-reactivity, but display varying degree of severity for their respective diseases. Parainfluenza viruses are closely linked to human and veterinary diseases.

One of the most common illness displayed in children is one of the upper respiratory tract. Some common methods for detecting these viruses include, cell culture, ELISA, immunofluorescent microscopy and PCR. The ELISA method is found to provide results which are comparable to the HAI procedure.


Human parainfluenza 1/2/3 IgG ELISA kit can be used to determine in-vitro levels of human IgG antibodies to parainfluenza 1/2/3 (parainfluenza-1 IgG, parainfluenza-2 IgG, parainfluenza-3 IgG) using samples of serum and plasma. This assay has a minimum analytical sensitivity limit of 1.04 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 IgG antibodies to parainfluenza 1/2/3 (parainfluenza-1 IgG, parainfluenza-2 IgG, parainfluenza-3 IgG) using current parainfluenza-1/2/3 IgG ELISA kit was 1.04 U/ml. The dynamic range for this assay is 1.0 – 125.0 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.
