Parainfluenza 1/2/3 IgA ELISA Kit

  • Created on the 7 September, 2017.

BACKGROUND

Parainfluenza viruses are classified as paramyxoviruses which can be grouped into 4 distinct single stranded RNA viruses (types 1, 2, 3, and 4). The viruses are negative sense RNA, approx. 15,000 nucleotides and 15-250 nm in size, they are also very closely associated with either human or veterinary disease. They tend to share antigenic cross-reactivity, however the severity of the disease is different for each of them. Parainfluenza type 1 probably causes croup, where type 3 can cause bronchiolitis and pneumonia in young infants. One of the most common illness found in children is of the upper respiratory tract displaying zero to low grade fever. The parainfluenza viruses can be detected through cell culture, PCR and immunofluorescent microscopy. ELISA and RIA assay procedure are able to provide results that are comparable to the HAI technique.

INTENDED USE

Human parainfluenza 1/2/3-IgA ELISA kit is intended for analysing in-vitro quantitative levels of human IgA antibodies against parainfluenza 1/2/3 using serum or plasma samples. This assay has a minimum analytical sensitivity limit of 0.96 U/ml.

SENSITIVITY

The minimum detection sensitivity level of human parainfluenza 1/2/3 IgA using this human parainfluenza 1/2/3-IgA ELISA kit was 0.96 U/ml. The dynamic assay range for this kit is 1.0 – 100.0 U/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.
