In EUROPLUS™ immunofluorescence tests antibody detection is performed using both tissue sections/cell substrates and monospecifically reacting antigen dots., Antibodies detected in IFT screening tests can therefore be differentiated or confirmed with one and the same reaction field. In some cases, the antigen dots help to extend the antigen spectrum, offering a wider range for screening., BIOCHIPs coated with purified or recombinant antigens in droplet form are used as monospecific substrates., A positive result shows green circular areas of antigen dots in front of a dark background under the microscope., In some EUROPLUS™ test systems several different antigens are coated on one BIOCHIP in separate antigen rows. In this manner, several monospecific analyses can be performed using a single BIOCHIP., Many different BIOCHIP combinations for various diagnostic investigations are available., Indirect Immunofluorescence, Microplate ELISA, Blot Techniques, Radioimmunoassays (RIA/IRMA), EUROmore...See more text
