Rapid Test ProⅡ for Total Milk is a qualitative test kit using a lateral flow device.
It is designed for the quick detection of milk protein from allergenic ingredients in unprocessed and processed food, as well as on environmental surfaces (swab test) and in rinse water.
The extraction buffer used in this kit is the same as ELISA KitⅡ and identical for all Rapid Test ProⅡ kits.
Therefore, Rapid Test ProⅡ retains superior performance in the detection of target proteins in both highly processed foods and raw materials.
The buffer in this kit is ready-to-use.
All materials such as tubes, pipettes and swabs are included in this kit.

Test Method
Lateral flow
No. wells
10 tests / kit
Limit of detection
Line 1 (upstream side)
Food: 4 µg/g (4 ppm) Casein
Surfaces (swab test): 0.8 µg Casein/100 cm2
Rinse water: 4 µg/mL (4 ppm) Casein
(4 µg/g Casein correspond to 5 µg/g (5 ppm) milk protein)
Limit of detection

Food: 0.5 µg/g (0.5 ppm) β-lactoglobulin
Surfaces (swab test): 0.1 µg β-lactoglobulin/100 cm2
Rinse water: 0.5 µg/mL (0.5 ppm) β-lactoglobulin
(0.5 µg/g β-lactoglobulin correspond to 5 µg/g (5 ppm) milk protein)
