OnSite III Allergen Lateral Flow Tests - Coconut

OnSite® III Allergen Lateral Flow Tests – Coconut is designed for use in the qualitative determination of coconut residues obtained from sampling foods (solids, powders, and liquids) and on surfaces. Though the prevalence of coconut allergy in Australia, the EU, Canada, and the USA is relatively low, the US FDA identified coconut as a food allergy in 2006. Law requires that food labels clearly indicate coconut content. To assist the food industry in establishing effective food safety practices, OnSite® Allergen III is a rapid food sampling test kit that can reliably detect Coconut residues in food and on surfaces and equipment.

The Coconut OnSite® III Allergen Kits consist of lateral flow devices (LFDs) that can be used to rapidly detect allergens in foods, rinse water and environmental surfaces (see link below to order). The LFDs are configured using antibodies that have been raised against the target allergen. To operate the kit, the sample is collected using the supplied scoop and then extracted for 2 min by shaking at room temperature. The tube is allowed to settle for 5 min by resting it. Thereafter, the sample extract is applied to the LFD using a dropper supplied with the kit. The fluid is wicked across the reagent zone, which includes a procedural control line (C), an overload line (O), and a test line (T). The inclusion of an overload line (O) is critical for testing foods that have high analyte contamination to prevent misinterpretation of false negative test outcomes.

Key Features

• Limit of Detection: Detects coconut allergens down to 1.0 ppm in food and rinse water and down to 1.0 µg/100 cm2 on environmental surfaces.
• Assay Time: ~ 20 min.
• Cross-Reactivity: None detected.
• Kit Components: OnSite® III LFD Devices (10), Single-Use Dropper (10), Breakaway Swabs (10), Pre-Measured OnSite® LFD Extraction Buffer (10), Instructions for use
• The test outcome is interpreted by visualizing the appearance of three lines at 15 min.
• Environmental surface testing requires separate purchase of the OnSite® Allergen Accessory Kit

Note: Coconut that contains certain preservatives such as sodium metabisulfite will greatly reduce detection capability.

The test is intended for laboratory use only and should only be performed by trained personnel.
