Finally, the blue fluorescence (ELFA) antigen (bacteria and protein) is detected by enzyme-linked immunosorbent assay. A sandwich technology is applied. The coating needle is coated with antibody. The measured fluorescence is directly proportional to the content of antigen in the sample.
● test scope
Pathogenic bacteria used in food and environmental samples include Salmonella, Listeria, Listeria monocytogenes, staphylococcal enterotoxin, Escherichia coli O157, Campylobacter, immunoconcentrated Salmonella and immunoconcentrated Escherichia coli O157.
● ready to use reagents
VIDAS disposable reagent is divided into two parts:
SPR, solid-phase receptor, whose inner side is coated by antibody, and the coated needle functions as a solid-phase pipette
The bar code marks the reagent strip, including all the required reagents, which can be used immediately after taking out. The type of test strip is identified by the color label and 3-letter mark on the test strip.
