OnSite® Allergen: Multiplex Tree Nut is a rapid, qualitative test that includes lateral flow devices (LFDs) designed to detect tree nut protein in rinsewater and on environmental surfaces. The test can simultaneously detect almond, cashew, hazelnut, pecan, pistachio, and walnut residues. To a lesser degree, the test can also detect coconut residues. Results obtained using these tests can be used as part of an effective Allergen Control Plan.

This kit relies on the use of polyclonal antibodies (pAbs) directed against the target allergens. It is configured with a test line (T) and a procedural control line (C). The test line (T) will produce a red line at low to medium levels of contamination, whether that contamination is from one or several target proteins. The procedural Control Line (C) should always produce a red line, regardless of the analyte concentration. Failure for this line to appear indicates a failure of the mixture to migrate across the membrane.

This test is intended for laboratory and industry use, including within food production facilities, commercial kitchens, contract laboratories, and auditing programs. These tests should only be performed by trained personnel. OnSite® Allergen Multiplex Tree Nut kits are not suitable for home/consumer use.

Key Features:

• Test works on surfaces and rinsewater
• Simultaneously detects almond, cashew, hazelnut, pecan, pistachio, walnut
• Detects as little as 1-5 mg/kg (ppm) of tree nut protein in rinsewater or 10μg/ 100 cm² on surfaces
• Requires no equipment
• Results in less than 20 minutes
• Sensitive to coconut protein at levels above 50 mg/kg (ppm)
