Tick-borne Encephalitis Virus IgG plus ELISA

$354.95 excl. VAT

Enzyme immunoassay for the detection and quantitative determination of human IgG antibodies against Tick-borne Encephalitis (TBE/FMSE) virus in serum and plasma. High sensitivity (100%) and specificity (100%), with a total assay time of 2-3 hours. The Plus kit contains a control protein not available in our standard TBE/FMSE IgG ELISA (ELS61239).


This Tick-borne encephalitis (TBE/FMSE) virus IgG plus antibody ELISA kit has been designed for the detection and the quantitative determination of specific IgG antibodies against Tick-borne encephalitis virus in human serum or plasma. The Plus ELISA contains an additional control protein, not present within our standard TBE/FMSE virus IgG antibody ELISA kit (ELS61239).

Microplates are coated with specific antigens to bind corresponding antibodies of the sample. After washing the wells to remove all unbound sample material a horseradish peroxidase (HRP) labelled conjugate is added. This conjugate binds to the captured antibodies. In a second washing step unbound conjugate is removed. 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 specific antibodies in the sample. Sulphuric acid is added to stop the reaction. This produces a yellow endpoint colour. Absorbance at 450/620 nm is read using an ELISA microwell plate reader.



  • High sensitivity – 100%
  • High specificity – 100%
  • Short assay time – <3 hours
  • 1 x 96 tests



Tick-borne encephalitis (TBE) virus is a flavivirus of the family Togaviridae. It is an enveloped single-stranded RNA virus with cubic icosahedral symmetry and ranges in size from 20-80nm in diameter. Three subtypes can be distinguished which show only little differences in their structural proteins. TBE virus is mainly transmitted by ticks (Ixodes ricinus, western subtype; Ixodes persulcatus, eastern subtype). The degree of contamination of ticks (and thus humans) in central Europe increases from west to east, and anybody may be affected. Specific antibody development yields a life-long immunity.

TBE is the most important tick-transmitted disease of man -beside Lyme disease, which is caused by the spirochete Borrelia burgdorferi. The clinical course of the disease depends on the immune status of the infected persons. A high virus production in the primary infected tissues is required for the passage of the blood-brain barrier and the resulting severe manifestations in the central nervous system.
