Description

Product Name Herpes Simplex Virus 1+2 (HSV) IgG - ELISA.
# of Samples 1 x 96 Assays.
Intended Use The HSV-1+2 IgG-ELISA is intended for the qualitative determination of IgG class antibodies against Herpes simplex virus Type 1+2 in human serum or plasma (citrate).
Introduction Herpes simplex is an enveloped DNA virus (150-200 nm in diameter) belonging to the alpha-herpesviridae. Based on antigenic, biochemical and biologically differences it can be divided into two serotypes, HSV-1 and HSV-2. Man is the only known natural host and source of the virus. HSV Type 1 typically causes oral herpes, while HSV-type 2 typically affects the genital area. Most of the time, HSV-1 and HSV-2 are inactive, or silent, and cause no symptoms, but some infected people have outbreaks of blisters and ulcers. Once infected with HSV, people remain infected for life. Herpes simplex viruses are amongst the most common infectious agents of man, and either HSV type appears to be capable of infecting similar body sites. A high percentage of the adult population is seropositive (appr. 90% HSV-1, in dependence on the socioeconomic status 10-30% HSV-2). Primary HSV-1 infection usually occurs in early childhood (6 to 18 months of age). HSV-2 usually produces mild symptoms, and most people have no recognized symptoms. Persons at risk are children with inherited T-cell deficiencies and patients who are immunosuppressed because of infection (e.g. HIV), transplantation, or cancer therapy.
The presence of virus resp. infection may be identified by
  • Microscopy: CPE, IF
  • PCR.
  • Serology: Detection of antibodies by ELISA.
Principles of the assay The qualitative immunoenzymatic determination of IgG-class antibodies against HSV Type 1+2 is based on the ELISA (Enzyme-linked Immunosorbent Assay) technique. Microtiter strip wells are precoated with HSV Type 1+2 antigens to bind corresponding antibodies of the specimen. After washing the wells to remove all unbound sample material horseradish peroxidase (HRP) labelled anti-human IgG conjugate is added. This conjugate binds to the captured HSV Type 1+2-specific antibodies. The immune complex formed by the bound conjugate is visualized by adding Tetramethylbenzidine (TMB) substrate which gives a blue reaction product. The intensity of this product is proportional to the amount of HSV Type 1+2-specific IgG antibodies in the specimen. Sulphuric acid is added to stop the reaction. This produces a yellow endpoint color. Absorbance at 450 nm is read using an ELISA microwell plate reader.
Storage and Stability The reagents are stable up to the expiry date stated on the label when stored at 2-8°C.
