Thanks to Block Scientific, I was able to procure the re-certified Bayer DCA 2000+ without hassles and get the lab back in operation. The
device works perfectly and I look forward to doing more business with Block Scientific.

Competitive Enzyme ImmunoAssay (ELISA) for the determination of antibodies to Hepatitis B core Antigen in human plasma and sera. For research use only.
The assay is based on the principle of competition where the antibodies in the sample compete with a monoclonal antibody for a fixed amount of antigen on the solid phase.
A purified recombinant HBcAg is coated to the microwells.The donor’s serum/plasma is added to the microwell together with an additive able to block interferences present in the
In the second incubation after washing, a monoclonal antibody, conjugated with Horseradish Peroxidase (HRP) and specific for HBcAg is added and binds to the free rec-HBcAg coated on the plastic.
After incubation, microwells are washed to remove any unbound conjugate and then the chromogen/substrate is added. In the presence of peroxidase enzyme the colorless substrate is hydrolyzed to a colored end-product. The color intensity is inversely proportional to the amount of antibodies to HBcAg present in the sample.
