Malachite Green lateral flow assay diagnostics rapid test card
tissue, Aquatic products
Overview:
Malachite Green (MG) rapid detection card is convenient, fast and
sensitive, suitable for on-site mass sample detection. The test
card contains an antigen in the test area (T) and an antibody ⅱ in
the control area (C) which are fixed in advance in the
nitrocellulose membrane. The gold label antibody in the micropores
was dissolved in the sample and incubated for 3 min. The solution
in the gold label micropores was added to the detection card and
sample well for 5-8 min reaction. According to T zone, C zone color
contrast interpretation results. Whether malachite green was
present or not, a purplish red band appeared in zone C.
Detection limit:
Fish, shrimp, bullfrog: 0.5 PPB (µg/kg)

Detection Procedure:
1. Please restore the product to room temperature before use;
2. Open the aluminum foil bag, take the required amount of gold
label microholes and test cards, mark them and put them on the
table (note: after removing the microholes, seal the aluminum foil
bag immediately to prevent moisture);
3. Take the sample to be tested 100 μL into the gold label
microhole, blow carefully until the purplish red particles at the
bottom of the hole are completely dissolved (note: blow gently to
avoid bubbles), and incubate at room temperature for 3 min.
Note: Samples should be tested immediately after processing!
4. Add all the gold label microporous solution into the detection
card and sample well, and interpret the result after 5-8 min
reaction.
Result Judgment:
Negative: C line color, T line darker than C line color or
consistent,The test results were negative.
Positive: C line is colored, T line is lighter than C line or T
line is light green, and the test result is positive.
Invalid: Line C does not display color, regardless of whether line
T displays color, the detection card is judged to be invalid.
