Feline Toxoplasma IgG antibody ELISA

Description

Intended use of the test kit

The Feline Toxoplasma ELISA test is designed to detect antibodies against toxoplasma infections. After washing, the strips are incubated with the cat sera or plasma to be tested. The strips are washed after incubation to remove unbound materials. A HRPO conjugated anti-species antibodies conjugate is added to detect bound cat antibodies to toxoplasma antibodies. After incubation and rinsing, the substrate is added and the optical density is measured at 450 nm.

Principle of the test kit

The test is based on the reaction of toxoplasma proteins with polyclonal cat antibodies. To this end toxoplasma proteins have been coated to a microtiter plate. The diluted cat serum/plasma sample is added to the wells of the coated plate.

• Qualitative
  The sample is added (diluted 1:100) to the wells of the coated plate.
• Quantitative
  The sample also can be titrated using a 3-step dilution, starting with a dilution 1:30 (> 1:90 > 1:270 > 1:810).

After washing the bound cat antibodies are detected by a HRPO conjugated anti-species antibodies
conjugate. The color reaction in the wells is directly related to the concentration of toxoplasma antibodies in serum/plasma samples.
