Walnut
Lateral Flow Walnut
Intended use:
The Lateral Flow Walnut assay is used for the qualitative detection of Walnut residues in surface samples got from e.g. production lines. The assay is also applicable for food samples. The assay is applied for the detection of small amounts of Walnut contaminations.
General Information:
Walnut contaminations in food possibly elicit hypersensitivity in sensitive persons. Food production lines have to be free of residues to prevent these allergic reactions. The effectiveness of cleaning can be verified by using the Lateral Flow Walnut Swabbing method.

SureFood® ALLERGEN Walnut – NEW
Intended use:
The test detects Juglans regia (walnut) DNA according to directive (EC) 1169/2011 and Juglans nigra (eastern black walnut) DNA qualitatively and/or quantitatively. Each reaction contains an internal amplification control.
For the quantitative determination the use of the laboratory reference material SureFood® QUANTARD Allergen 40 containing 40 mg walnut / kg food sample and a detection system including a standard dilution is required.
For DNA preparation, the use of SureFood® PREP Advanced, protocol 1, is recommended.
General Information:
The real-time PCR assay can be used with established real-time PCR instruments capable of detection of at least two fluorescence dyes. Internal validation was performed on Roche LightCycler® 2.0, Roche LightCycler® 480 II, Roche cobas® z 480 Analyzer, Qiagen Rotor-Gene Q, Applied Biosystems 7500, Bio-Rad CFX96, Bio Molecular Systems MIC, LTF MyGo Pro, AriaDx and Agilent Mx3005P.

SureFood® ALLERGEN 4plex Peanut/Hazelnut/Walnut+IAC
Intended use:
This multiplex test detects specific DNA sequences of peanut, hazelnut and walnut.
For DNA-preparation the use of SureFood® PREP Advanced, protocol 1 is recommended.
General Information:
