VIP Gold (Visualimmuno Precipitate) is a lateral flow immunoassay for the detection of pathogens in food and environmental surfaces. Once added to the test device, samples are combined with gold-colloid particles coated with capture antibodies specific to the target antigen and drawn across a nitrocellulose membrane via capillary action. If the target antigen is present in the sample, it is captured and bound to the colored particles. The particles continue across the membrane encountering a test line containing antibodies specific to the target antigen followed by a control line containing antibodies specific to the capture antigen coated to the colored particles. If present, the target antigen and its associated particles will become bound to the test line antibodies to form a visually apparent line. The remaining particles will continue to the control line antibodies to form a visually apparent line verifying that the test device worked correctly. Each VIP Gold device is a self-contained test that requires only the addition of sample, making it an extremely simply and user-friendly method ideal for low to medium volume labs.
VIP Gold is a single-use, lateral flow test device incorporating highly specific antibodies for the rapid detection of
- E. coli O157:H7 in foods and environmental samples
- Listeria spp.
VIP Gold for EHEC utilizes mEHEC® enrichment media, uniquely formulated to promote the rapid growth of E. coli; providing results in as few as 8 hours for beef and produce samples.
Improved Lab Efficiency
VIP Gold offers an innovative multi-test format with break-away devices designed for maximum flexibility to accommodate a wide range of testing volumes.
The cutting edge particle technology allows for faster sample flow, producing a clean background, clear lines and easy to read positive/negative results without the need for a reader.
