Cytomegalovirus (CMV) IgG ELISA Kit

INTENDED USE

Human CMV IgG ELISA kit is intended for analysing in-vitro quantitative levels of human IgG antibodies to cytomegalovirus (CMV, CMV-IgG) in plasma or serum samples. This assay has a minimum analytical sensitivity limit of 1.29 U/ml.

BACKGROUND

Cytomegalovirus (CMV) is a member of the herpes family of viruses and it can be spread by blood, saliva, urine, breast milk, vaginal fluids and semen. This means that some possible modes of transmission include blood transfusions, organ transplants, breastfeeding and sexual contact. If a person becomes infected then this virus can remain inactive within their body throughout their life. Infants which are born to mothers that are infected with CMV during pregnancy could develop congenital cytomegalovirus infection. Individuals that have a weak immune system are prone to CMV causing serious diseases/illnesses such as hepatitis, pneumonia, retinitis, encephalitis or colitis). There is the possibility of antiviral treatments which could improve the prognosis in some patients with cytomegalovirus infections. However, currently there are no CMV vaccines that are commercially available. Some of the laboratory techniques that have been used to study this virus are CF and ELISA methods. Serologically either IgG or IgM antibodies can be determined and quantitated, as well as the avidity of the IgG molecules can be measured.

CMV IGG ELISA KIT CONTENT

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.

  • Cytomegalovirus antigen coated microtiter strips.
  •  Calibrator A (Negative Control).
  • Calibrator B (Cut-Off Standard).
  • Calibrator C (Weak Positive Control).
  • Calibrator D (Positive Control).
  • Enzyme Conjugate.
  • TMB Substrate.

SENSITIVITY

The minimum detection sensitivity level of of IgG to cytomegalovirus (CMV-IgG) using current human CMV IgG ELISA kit was 1.29 U/ml. The dynamic range for this assay is 1.0 – 90.0 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.
