The CleanTrust^TM Surface Protein Allergen Test Swab is a ready to use rapid test swab with high sensitivity,used to detect protein residues on surface, and thereby determine if cleaning has been effective in eliminatingproteins, including potentially allergenic proteins. After smearing the surface of the object, if protein is present,the solution will change from green to purple. The faster and darker the color change, the higher the proteincontent. lt is important to note that a residue may contain a mixture of allergenic and non-allergenic proteins,as well as non-protein materials.

Benefits:

• Easy to use, no extra reagent needed

• Visual interpretation, no instrument needed

• 
  

• High sensitivity, detects as little as 5 ug of protein

• Suitable for protein-based allergens monitoring
  

Product No: YL0200

Detection Sensitivity: 

5 µg after 15 minutes incubation at 37°C

Applicable Scope: Surface of the target subject.

Storage & Shelf Life: 2-8°C , store away from light, valid for 12 months

Operation Procedure:

1) Place the swabs at room temperature to reach ambient temperature (21-25°C) before performing the test. Hold the top of the swab tube and gently twist the swab out of the tube (do not pull the tube straight out!). 

2) Use the cotton tip for sampling, wipe the surface of the object evenly, rolling and wiping in a Z shape, wiping an area of about 10*10cm. After sampling, put the cotton tip back into the swab tube. (For irregular surfaces, ensure the swabbing technique remains consistent for each test and swab a large enough area to collect a representative sample). 

3) Break the snap valve, squeeze the bulb to expel all the liquid down to the swab shaft, bath the cotton tip in the liquid by shaking for 10 seconds. 

4) Incubate for 15 minutes at 37°C, compare the color of reagent in the tube to the color chart on the tube label and record the result.
