Tetracycline residue rapid test device.
40 pcs/kit.
1. Intended use:
The salbutamol residue rapid test card is a rapid, one step test for the qualitative detection of salbutamol in meat samples. The whole time of assay is only approx. 15~25min.
2. Summary:
Salbutamol belongs to the group of G-agonists. It can promote animalí»s fat metabollism, and accelerate the growth of animal. However, this is prohibitted. Except for its lipolytic and anabolic effect, salbutamol is used as antiasthmatic and tocolytic agent which has a slacken effect on non-striated musculature. It can remain in animalí»s body and may lead to strong effect to human. If for worse, it may threaten peopleí»s life. Salbutamol is prohibitted for using in most countries.
The salbutamol residue rapid test card is a rapid test to qualitatively detect the presence of salbutamol in specimen at the sensitivity of 58g/kg. The major advantage of the one step test device is that the result can be observed easily .
3. Principle:
The principle is the antigen-antibody reaction. The one step test device is a competitive immunoassay of which the detector reagent consists colloidal gold particles that is coated with affinity purified anti-salbutamol antibodies. The capture reagent in the assay is salbutamol-protein conjugate, which is immobilised on the membrane of the test device. The specimen migrates over the membrane. The more analyte in the sample, the more effectively it will compete with the salbutamol immobilised on the membrane for binding to the limited amount of antibodies of the detector reagent.. If salbutamol in the specimen is above 58g/kg, it will prevent the binding of the detector reagent with the salbutamol immobilised on the membrane, resulting in positive.
Intended use:
Toxoplasma IGG/IGM rapid test is a rapid immunochromatographic test for the simultaneous detection of IGM and IGG antibodies to toxoplasma gondii in human serum/plasma. The test can be used as a screening test for toxoplasma infection and as an aid for differential diagnosis of the self limiting primary toxoplasma infections and the potentially fatal secondary toxoplasma infections in conjunction with other criteria.
Test principle:
The toxoplasma IGG/IGM rapid test is a lateral flow chromatographic immunoassay. The test cassette consists of:
1) A burgundy colored conjugate pad containing toxoplasma recombinant envelope antigens conjugated with colloid gold (toxoplasma conjugates) and rabbit igg-gold conjugates,
2) A nitrocellulose membrane strip containing two test bands (t1 and t2 bands) and a control band (c band). The t1 band is pre-coated with the antibody for the detection of IGM anti-toxoplasma, t2 band is coated with antibody for the detection of igg anti-toxoplasma, and the c band is pre-coated with goat anti rabbit IGG.
Absence of any t bands (t1 and t2) suggests a negative result.
The test contains an internal control (c band) which should exhibit a burgundy colored band of the immunocomplex of goat anti rabbit igg/rabbit igg-gold conjugate regardless of the color development on any of the t bands. Otherwise, the test result is invalid and the specimen must be retested with another device.
Reagents and materials supplied :
1. Test cassette individually foil pouched with a desiccant.
2. Plastic dropper
3. Buffer
4. Package insert.
Storage and stability:
The kit must be stored at 2-30pc.
Warning and precautions:
1. For in vitro diagnostic use only. Not for medicinal use.
2. Do not use beyond expiry date.
3. Read the instructions careful y before performing the test.
4. Handle all specimen as potential y infectious.
5. Follow standard biosafety guidelines for handling and disposal of potential y infective material.
Detection of e. Coli o157 article qualitative detection of colloidal gold feces, food, water and other samples of e. Coli o157. The degree of color is proportional to the sample bacteria. Enrichment effect well. Can be used to treat samples in rapid screening, positive samples can be isolated bacteria, reduce the workload.
Steps:
1. Will be placed on the detection of clean, dry working platform.
2. Provided with the kit with clean straw or from the pipette to take samples or enrichment sample 2 drops, drops added to the test sample by adding end section (detection section white side), start timing;
3. 2-15 minutes of observation, 15 minutes after the results do not count.
[Results judge] negative: a red line appears, which appears in the control line position of a red line; positive: two red lines appear, that in the test line and control line positions are there red line; invalid: no red line appears that the test line and control line in the position not appear red.
[Treatment of samples to be tested]
1. Direct detection: direct detection of water will be.
2. By bacteria detection
(1) stool samples: the samples of the inoculated immediately take 1 gram of 9ml of mec broth, 37 constant temperature shaking culture 6h.
(2) food samples: the 25 g samples of ground, and immediately inoculated in 225ml of mec broth, 37 constant temperature shaking culture 9h.
(3) water samples: water samples will be 400ml immediately inoculated in 5 times concentrated mec 100ml in broth, 37 constant temperature shaking culture 16-20h. 3. Proposed use of enrichment broth was added 20mg / l novobiocin the ec modified broth.
[Interpretation of the results]
1. Enrichment after negative results may be judged as negative.
2. Or by direct detection of bacteria have positive results, the pathogen can be isolated.
3. Negative result does not have a precise meaning. [storage] 4-30 , cool dark dry place.
