5. Principle
The
Crystal violet rapid test card is based on competitive inhibition immuno-chromatographic principle. In the flow process, Crystal violet in
the sample combined with Crystal violet
specific colloidal gold-labeled monoclonal antibody, Inhibit the combination
between antibody and Crystal violet-BSA
conjugate on Test line of NC membrane, lead to the color change of Test line.
When the sample has no Crystal violet residue or
concentration lower than detection limit, T line is darker than C line or T
line has same color with C line; when the concentration is equal to or higher
than detection limit, T line is obviously lighter than C line or T line has no
color. No matter whether there is Crystal violet residue in sample, C line
will appear, it means the test is valid.
6. Materials required but not provided
1) Equipment: Homogenizer,
nitrogen-drying device, vortex(optional), centrifuge, Micropipette, balance (a
reciprocal sensibility of 0.01 g);
2) Consumables: 15ml centrifuge tube,
disposable tips.
7. Sample preparation
1) Take 3±0.05g homogenized tissue sample into 15ml centrifuge
tube, add 2ml Reagent 1, then add 6ml reagent 2, shake by hand or
by vortex strongly for 2min (shake by hand up-and-down strongly), add 1 bottle
of reagent 3, shake strongly for 2min (shake by hand up-and-down
strongly), then centrifuge at 4000r/min for 5min;
2) Transfer 3ml up-layer
clear liquid into another centrifuge tube, add 100μl reagent 4, shake
for 30S. Blow to dry at 56℃ by Nitrogen or air(or use hair
dryer);
3) Add 0.5ml reagent 5, shake for 2min (add a 200ul tips into the centrifuge tube)
to fully dissolve the residue on wall of centrifuge tube, absorb 120ul
down-layer liquid as sample, ready to test.
8. Operation
procedures
8.1 Read the instruction
carefully before use. Return test cards and sample into room temperature.
8.2 Take out test bag,
open and take out required microwells, making proper marks. Please use them
within 1h. Seal the test bag, avoid moisture.
8.3 Take 120ul of the
test samples into the microwells, then repeatedly pump and suck for many times, mix the sample with the reagent in the microwells completely until no
solid judged by eyes (this is a very important step). Incubate for 1-2min at room temperature (20-25℃).
8.4 Put the test card
flatly, absorb the 80µl liquid from the
micro-well, add into the “S” hole
on test card.
8.5 Be static, read the
result in 5~8min, it is invalid in other time.
9. Test Result Interpretation
9.1 Negative: T line is
darker than C line, or T line has same color with C line. It means there is no Crystal violet residue in sample
or the residue is lower than detection limit.
9.2 Positive: T line is obviously lighter than C line or T line is
invisible or T line appear green
or blue color.
It means the Crystal violet residue is equal
to or higher than detection limit.
10. Precautions
1) The test card can be
used only once at room temperature, do not use test card out of expiry date.
2) Do not touch the
white membrane surface in the middle of test card, avoid sunlight and fan
blowing directly.
3) Test again for
positive result;
4) Please contact the
supplier for any questions.
11.Specificity
Test 500ppb
Tetracyclines, Quinolones and Sulfonamides etc. The result is Negative.
12. Storage
and expiry date
Storage: Store at 4-30 ℃ in dark,
sealed, dry place, no frozen.
Expiry
date: 12
months; date of production is on box.
