Antibodies against Borrelia

EUROPLUS Borrelia afzelii, Borrelia burgdorferi, VlsE and OspC antigens

Antibodies against Borrelia afzelii, VlsE (top), Borrelia burgdorferi and OspC (bottom).
  • Sensitive screening test for the detection of anti-Borrelia antibodies.
  • Indications: erythema chronicum migrans, lymphadenosis cutis benigna, lymphocytic meningoradiculitis, carditis, arthritis, acrodermatitis chronica atrophicans, neuroborreliosis.
  • Initial dilution 1 : 10 (IgM), 1 : 100 (IgG).
  • If antibodies against Borrelia afzelii or Borrelia burgdorferi are present, a distinct fluorescence of the bacteria in the smear is obtained.
  • With the VlsE or OspC coated BIOCHIPs antibodies against the highly specific and highly sensitive marker antigens VlsE (IgG) or OspC (IgM) can be determined monospecifically in one and the same test procedure. If these antigens fluoresce the antibody result is positive even if the bacteria smears show a negative reaction. Thus, the BIOCHIP Mosaic helps to increase specificity and sensitivity in Borrelia diagnostics.
  • The BIOCHIP can be supplemented as required using further substrates, e.g. Borrelia burgdorferi sensu stricto (strains CH or USA) and TBE virus infected cells.

Anti-Borrelia plus VlsE and anti-Borrelia (IgM)

  • Sensitive screening test for the detection of anti-Borrelia antibodies.
  • Indications: erythema chronicum migrans, lymphadenosis cutis benigna, lymphocytic meningoradiculitis, carditis, arthritis, acrodermatitis chronica atrophicans, neuroborreliosis.
  • Serum dilution 1 : 101; conjugate class anti-IgG or anti-IgM or anti-IgAGM (VlsE: -IgG only), POD-labelled.
  • 3-point calibration (IgG and IgM). Identical incubation conditions and times: all tests can be combined without difficulty on one and the same microplate.

VlsE (variable major protein-like sequence, expressed) is a surface protein of Borrelia which is expressed exclusively in vivo and which contains conserved and highly immunogenic epitopes.
  • IgM test kit (Anti-Borrelia) includes IgG/RF absorbent in sample buffer for IgG absorption in preparation for the determination of specific IgM class antibodies.

Anti-Borrelia plus VlsE ELISA  (IgG) EI 2132-2 G
Anti-Borrelia ELISA (IgM)EI 2132 M

Antigen ELISA for detection of CXCL13 in CSF in neuroborreliosis

  • First CE-labelled test
  • Early-phase marker for acute neuroborreliosis: high concentrations of CXCL13 can often be detected already at the start of illness – often before antibodies against Borrelia are detectable
  • Therapy marker: the CXCL13 concentration in CSF drops with successful antibiotic therapy
  • Differentiation between acute and past neuroborreliosis: a pathological ASI/LSQrel indicates,
    together with
    - a low CXCL13 concentration in CSF – acute neuroborreliosis unlikely 
    - a high CXCL13 concentration in CSF – acute neuroborreliosis very likely 
  • 6 calibrators and 2 controls provided in the test

Anti-Borrelia plus VlsE (IgG) and anti-Borrelia (IgM) – antibody determination in serum and CSF for detection of intrathecal synthesis of specific antibodies against Borrelia

Table-based evaluation of the CSQrel.
  • Antibody determination in serum and cerebrospinal fluid (CSF).
  • Indication: neuroborreliosis.
  • CSF dilution 1 : 2, serum dilution 1 : 404; conjugate class anti-IgG or anti-IgM, POD-labelled.
  • 4-point calibration, quantitative.
  • Optional 5-point (IgM) or 6-point calibration (IgG) provides a wider measurement range and reduces the number of dilutions/incubations needed (additionally required calibrators included in the test kit).

Anti-Borrelia EUROLINE-RN-AT-adv

Incubated Anti-Borrelia EUROLINE-RN-AT-adv
  • Specific confirmatory test in line blot format for the detection of IgM antibodies against Borrelia.
  • Indications: erythema chronicum migrans, lymphadenosis cutis benigna, lymphocytic meningoradiculitis, carditis, arthritis, acrodermatitis chronica atrophicans.
  • The Anti-Borrelia EUROLINE-RN-AT-adv is based on a selection of diagnostically relevant recombinant Borrelia antigens for the detection of specific antibodies of class IgM. The most important antigen contained in the test is covalently bound, dimeric OspC advanced (European patent EP 2 199 303 A1) from four human pathogenic Borrelia strains (B. afzelii, B. burgdorferi, B. garinii, B. spielmanii). OspC advanced is over 30% more specific than conventional recombinant OspC antigens. Through the use of four OspC advanced variants, IgM antibodies of all relevant human pathogenic Borrelia genospecies are reliably detected.
  • Automatable incubation (EUROBlotMaster or EUROBlotOne) and software-based evaluation (EUROLineScan)
  • Serum dilution 1:51, conjugate class anti-human IgM, AP-labelled.

Anti-Borrelia EUROLINE-RN-AT

Incubated Anti-Borrelia EUROLINE-RN-AT
  • Specific confirmatory test for the detection of antibodies against Borrelia.
  • Indications: erythema chronicum migrans, lymphadenosis cutis benigna, lymphocytic meningoradiculitis, carditis, arthritis, acrodermatitis chronica atrophicans, neuroborreliosis.
  • The Anti-Borrelia EUROLINE provides a unique mixture of Borrelia specific antigens in a user-friendly line blot format. In addition to the major serological early markers OspC (IgM) and VlsE (IgG) – in each case from B. afzelii, B. burgdorferi and B. garinii – it contains highly specific p39 (Bmp) and the late marker p83. Five new, recombinant designer antigens (p18, p19, p20, p21, p58) having a very high specificity (IgG) were identified using bioinformatic analysis of the Borrelia genome. For the first time, lipids which have been proven to be immunoreactive and were extracted from the Borrelia membrane are available on the line blot.
  • The Anti-Borrelia EUROLINE-RN-AT (IgG) can also be used for qualitative detection of specific intrathecal antibody synthesis in neuroborreliosis.
  • The serological hit rate is increased by 10% by using three OspC variants in the IgM test.
  • Serum dilution 1 : 51; conjugate class anti-IgG or anti-IgM, AP-labelled.

Anti-Borrelia EUROLINE-WB (whole antigen plus VlsE)

Incubated Anti-Borrelia EUROLINE-WB
  • Specific confirmatory test for the detection of antibodies against Borrelia.
  • Indications: erythema chronicum migrans, lymphadenosis cutis benigna, lymphocytic meningoradiculitis, carditis, arthritis, acrodermatitis chronica atrophicans, neuroborreliosis.
  • Serum dilution 1 : 51; conjugate class anti-IgG or anti-IgM, AP-labelled.
  • Antigens: SDS extract of a Borrelia afzelii strain.
  • EUROLINE-WB is a combination of westernblot and line blot techniques. An SDS extract of a Borrelia afzelii strain is electrophoretically separated according to molecular mass and transferred onto a nitrocellulose membrane. A membrane chip coated with highly purified recombinant VlsE-Antigen is then added to the westernblot strips.
  • By additionally determining antibodies against VlsE the serological hit rate can be increased by 20% compared to whole extract Westernblots and by 30% compared to recombinant antigen Westernblots. Of all recombinant antigens, VlsE possesses the highest sensitivity for the detection of a Borrelia infection. Over 85% of IgG-positive sera could be identified at a glance by assessing the VlsE band. VlsE allows detection of antibodies against all Borrelia species, and the risk of a false negative reaction due to species differences is ten times lower.
