Lateral Flow Cashew Kernel


Intended use:

The Lateral Flow Cashew Kernel assay is a qualitative detection assay of Cashew Kernel 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 Cashew Kernel contaminations.

General Information:

Cashew 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 Cashew Kernel Swabbing method.

SureFood® ALLERGEN Cashew – NEW


Intended use:

The test detects cashew DNA according to directive (EC) 1169/2011 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 cashew / 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.

Art. No. S3615
Test Format Test-Kit with 100* reactions
Sample Preparation 1. DNA preparation, e.g. SureFood® PREP ALLERGEN 2. Preparation of Allergen-PCR mix 3. Pipetting of samples and PCR mix 4. Check PCR protocol settings 5. Start PCR run
Detection Limit Depending on the sample matrix, processing grade, DNA preparation and DNA contant, the detection is limited to < 5 DNA copies / ≤ 0.4 ppm.
Shelf life 12 month
Additional Information The detection system system can be used on all available real-time PCR cyclers.ABI Prism
