Biocan Tell Me Fast is an immunochromatographic assay used for qualitative detection of Salmonella. This test is intended for the preliminary detection of Salmonella in food and environmental samples.

Salmonella is a genus of rod-shaped Gram-negative bacteria of the Enterobacteriaceae family. Salmonella are found in both cold and warm blooded animals, and the environment. Strains of Salmonella cause illness such as typhoid fever, paratyphoid fever, and Food poisoning. Salmonella is the etiologic agent of Salmonellosis in humans, causing severe illness in infants, the elderly, and immunocompromised patients.

Biocan Tell Me fast Salmonella is a rapid immunoassay in lateral flow test device format. It detects the presence of Salmonella organism directly from the enrichment medium sample. The Salmonella rapid test is performed on test strips consisting of sample pad, conjugate pad containing dried detection reagent, nitrocellulose membrane lined with test and Procedural control lines, and absorbent pad. The sample is applied to sample pad and flows through test strip by capillary action. As the sample moves through the conjugate pad, it solubilize the detection reagent consisting of nano-gold particles coated with anti-Salmonella antibodies. If the Salmonellai organism is present in the sample, a complex of the microorganism and nano-gold particles will form and be captured by anti-Salmonella antibodies present in the Test line, as the complex flows through nitrocellulose membrane. The visible colored test line indicates accumulation of this complex in positive samples, while negative samples are indicated by clearly visible control line. Each strip has Procedural control line to control for reagent stability and functionality. A clearly visible Procedural control line indicates that the reagents have flowed normally through the test strip.
