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 2-30 c. 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.
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.

UV curing is a photochemical process by which monomers undergo curing (polymerization or cross inking) upon exposure to ultraviolet radiation. A specially formulated monomer will polymerize when exposed to ultraviolet radiation. This UV "curable" monomer includes a sensitizer which absorbs UV energy and initiates a polymerizing reaction in the monomer. KW-4AUV is specially designed for curing photosensitive coatings and thin films. It equips two UV light sources with radiations at 365 nm and 245 nm. The coated substrates up to 6?in diameter will be rotated at 6 rpm to ensure uniform curing. The built-in interlock door to prevent the exposure of UV radiation gives safe operation. In conjunction with the KW-4A spin coater, the system can be used to make various coatings and thin films via the photochemical process.
