Respiratory Syncytial Virus (RSV) IgA ELISA Kit

  • Created on the 8 September, 2017.


Human RSV IgA ELISA kit is intended for determining in-vitro quantitative levels of human IgA antibodies against respiratory syncytial virus (RSV IgA) in serum or plasma. This RSV-IgA ELISA kit has a minimum analytical sensitivity limit of 1.7 U/ml.


Respiratory-syncytial virus (RSV) is a syncytial virus that is responsible for causing infections of the respiratory tract and lungs. It is a single stranded, negative sense RNA virus which belongs to the Pneumoviridae family. Human RSV is an approx. 120–200 nm enveloped virus which contains a linear negative-sense RNA genome and a lipoprotein coat. There are four viral genes which code for intracellular proteins that are involved in processes such as replication, transcription and particle budding. These are called matrix protein (M), “large” protein (L), Nucleoprotein (N) and phosphoprotein (P). The genome itself is about 15,000 nucleotides in length and is made up of single stranded RNA (displaying negative polarity) and it contains 10 genes in total which encode 11 proteins. RSV is mainly transmitted through large droplets and also by secretions from contact with any infected people. The virus has an incubation period of 3-5 days before the symptoms begin to appear. ELISA assay have played important role for the serological diagnosis of RSV infections because of their sensitivities, specificities and the ability to allow differentiation of antigens into the various immunoglobulin classes. The following RSV IgA ELISA kit is ideal for measuring various diagnostic applications.


The minimum detection sensitivity level of IgA antibodies to respiratory syncytial virus (RSV-IgA) using current human RSV IgA ELISA kit was 1.7 U/ml. The dynamic assay range for this kit is 1.0 – 100.0 U/ml.

Your secretory IgA ELISA kit 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 kit performed well and I was happy with the results that were generated.

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.

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