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

BACKGROUND

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.

INTENDED USE

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.

SENSITIVITY

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.
