Brucella OPS iELISA

The world’s most versatile ELISA kit for the detection of cattle brucellosis

THE FIRST ELISA THAT USES THE SAME ANTIGEN AS THE FPA

General

Information

Ellie’s BRUCELLA OPS iELISA is a semi-quantitative test kit based on indirect ELISA technology. Plates are coated with B. abortus O-chain polysaccharide (OPS), which is the same antigen used in the Brucella FPA (product code B1001).

  • THE FIRST ELISA THAT USES THE SAME ANTIGEN AS THE FPA
  • RUNS INDIVIDUAL OR POOLED SERUM SAMPLES & INDIVIDUAL OR BULK MILK SAMPLES

In addition to monitoring bulk milk antibody levels, the Brucella OPS iELISA can also be used for export/import purposes, confirmatory testing, or screening of vaccinated and non-vaccinated animals. It is a robust, versatile, highly sensitive, and highly specific test. 

It complements the Brucella FPA by adding bulk milk testing and high sensitivity when testing animals in a negative population.

B1001- 250 (250 tests kit)

B1001- 1000 (1000 tests kit)

This product is a new version of the original Brucella FPA test kit. Three components of the test kit (Positive Control, Negative Control, and the Tracer) have remained unchanged from the original Diachemix® Brucella FPA, product code B1001. The new formulation of the Sample Diluent provides more consistent data on the negative population of animals because it is better at handling sample background and interference. This kit contains a mix of both A and M tracers. It tests for the presence of B. melitensis and B. abortus antibodies in serum and milk from various species. Milk testing requires the use of ClearMilk™ Buffer, product code C1001.

B1002- 250 (250 tests kit)

B1002- 1000 (1000 tests kit)

This product is a qualitative test that uses Fluorescence Polarization technology to detect the presence of antibodies specific for smooth colony-producing Brucella species (B. melitensis, B. abortus, and B. suis – Rev. sci. tech., OIE 1982) in patient serum. The presence of antibodies is indicative of a prior Brucella infection.

Ordering informationB1003-250 (250 tests kit)

This product is a qualitative test that uses Fluorescence Polarization technology to detect the presence of antibodies specific for smooth colony-producing Brucella species (B. melitensis, B. abortus, and B. suis – Rev. sci. tech., OIE 1982) in individual or bulk milk samples. It can be performed in the field, and it is used on smaller farms to quickly assess the problem. The presence of antibodies is indicative of a current or recent Brucella infection.
