AllerSnap is a quick and easy way to verify the cleanliness of surfaces by detecting protein residues left behind after cleaning. By simply swabbing the area and activating the device, you release a reagent that turns color, providing a qualitative and semi-quantitative result of the protein levels on the surface: green means clean and purple means re-clean. The more protein present, the quicker the color change to purple and the darker the color. AllerSnap quickly validates surface hygiene, allowing immediate corrective action to be taken when necessary.

Benefits

• Results in 15-30 minutes depending on sensitivity requirements
• Proactive, qualitative approach to verification 
• Broad range, non-specific protein screening is more cost-effective when specific tests are not required
• Eliminates mistakes and waste
• No separate wetting agent required
• No reconstitution step ensure consistent repeatable results

Method Comparison

	Method 1	Method 2
Foodstuffs	ALLER-Snap*	Allergen Test (ELISA)*
Shrimp	10 ppm	5 ppm
Wheat (Flour)	10 ppm	5-75 ppm
Peanut Butter	1 ppm	0.5-5 ppm
Egg whites	1 ppm	4-25 ppm

Notes:

* ALLER-Snap sensitivity levels shown are based on incubation at 55°C for 15 minutes or 37°C x 30mins for max sensitivity.

* Studies show that the recovery of allergens from surfaces are very variable and inefficient with 4 – 27% recovery when tested by ELISA methods. Sensitivity data shown is based on information available online. Order number: ALS-100 (100 tests per case)
