The Goat milk adulteration rapid test strip is convenient, fast, sensitive and can be used for on-site large-scale testing. There are 2 test lines and 1 control line on the strip: Casein (T1) and Lactoglobulin (T2). Mix the milk with the reagent in the micro-well completely, then incubate at 50℃ for 3 min. Insert the strip into micro-well for 5 min, then read the result by the color of C line (Control Line) and T line (Test Line). No matter whether there is milk, casein and lactoglobulin in sample, C line will appear, it means the test is valid.
1. Read the manual before experiment. Keep the test kit and samples under room temperature. Goat milk sample should be fully liquid without any quality change, agglomeration or sediment.
2. Take wells and strips from the bottle and mark numbers on them (Immediately close the bottle after using it.)
3. Take 200ul of the milk sample into the micro-well and carefully mix it until the purple particles dissolve and change to pink color. Incubate the wells under 50℃ for 3 min.
4. Insert the test strips into wells and make sure the sample pad is fully soaked in the milk, for 5 minutes.
5. Take out the strip and clean the sample pad (either cut off or use paper tower to erase it), then read the result based on Line C and Line T.
All of the T Line (T1 & T2) and C Line are red, and color of T Line is deeper than C Line.
a. Milk Positive: C Line is red, both T1 and T2 line is lighter than C Line or the same with C line. We consider that there is milk in the sample.
b. Casein Positive: C line is red. T1 line is lighter than C Line or the same with C line. But T2 line is deeper than C line. We consider that there is casein in the sample.
c. Lactoglobulin Positive: C line is red. T2 line is lighter than C Line or the same with C line. But T1 line is deeper than C line. We consider that there is lactoglobulin in the sample.
If C Line does not show up, we consider the test is invalid. Please repeat the test based on our manual.
