We are offering bt combo strip test. Reagen bt combo strip test is a qualitative and rapid lateral flow assay designed to detect both beta-lactam and tetracycline antibiotic residues in raw commingled cows milk. This test uses a tetracycline receptor and a novel beta-lactam binding protein which eliminates the need for a heating block. this test is designed for point-of-care use or reference lab settings. the unique features of the kit are: rapid strip test method 7 minutesnovel binding protein that requires no heating stephigh sensitivityhigh reproducibility mechanism of reaction c-line indicates the presence of the corresponding antibiotic in the milk. The greater the reduction in signal intensity at the test line, the greater the concentration of tetracycline or beta-lactam antibiotics present in the milk. the assay is also designed to simultaneously detect tetracycline andbeta-lactam antibiotics. kit contents, storage and shelf life the reagen bt combo strip test has the capacity for 96(rns92005-01) or 192 (rns92005-02) determinations. the shelf life is 12 months when the kit is properly stored. the positive and negative control vials contain lyophilized raw milk samples, and must be reconstituted with 1 ml of distilled water before use. The positive control vial is spiked with 4 ppb penicillin g and 100 ppb of oxytetracycline. The reconstituted raw milk controls are stable for 48 hours at 4c. Additional positive and negative control vials are available separately rns92005-01 the assay uses a competitive colloidal gold based format. The milk sample (200 l) is added to a clear plastic reaction vessel, and used to resuspend the lyophilized reagents to a uniform pink color in the bottom of the microtiter wells. The milk is incubated briefly (3 min) to allow the both antibiotic binding proteins on the gold particles to engage with any antibiotic present in the milk. The test strip is then inserted into the sample well with the arrows pointing downward initiating capillary flow up the strip. Any gold particles that are not complexed with antibiotics present in the milk will bind to their respective test line, forming a signal (red line) at that position. each test strip is imprinted with two test lines and one control line (c -line). one test line allows for the detection of tetracyclines, and the other for the detection of beta -lactam antibiotics. If the binding protein on the gold particle has engaged with either a tetracycline or a beta-lactam antibiotic present in the milk sample, the gold particle will flow past the test line corresponding to that antibiotic and reach the c-line. For visual interpretation of the test results, any test line signal intensity that is stronger than the signal at the c -line indicates a negativeresult. signal at any test line which is equal or less intense compared to th e rns92005-02 kit contents amount storagereaction wells 12 x 16 (192 total) 4c test strips 12x 16 strips(192 total) positive control 2 vials negative control 2 vials pipette tips 200 tips rt a 96-well plastic frame is also provided in each kit to anchor the reaction vessels in place during testing, and can be re-used as required. sensitivity (detection limit) beta-lactam antibiotics tetracycline antibioticspenicillins cefalosporins antibiotic(mrl) detectionli mit( ppb) antibiotic(mrl) detection limit (ppb) antibiotic (mrl) detection limit ppb)penicilling (4) 3-4 ceftiofur(100) 75-100 tetracycline(100) 50-75ampicillin(4) 4-5 cephapirin(60) 6-15 chlorotetracycline(100) 20-50amoxicillin(4) 4-5 cefazolin(50) 35-50 doxycycline(100) 10-35cloxacillin(30) 4-8 cefoperazone(50) 5-20 oxytetracycline(100) 30-55oxacillin(30) 4-8 cephquinome(20) 10-20 dicloxacillin(30) 5-8 cephalonium(10) 3-10 nafcillin(30) 15-30 required materials not provided with the kit timeradditional positive and negative controlspolypropylene tubesdistilled waterscissors to cut strip capsfixed-volumer pipettor to deliver 200 l

We are offering aflatoxin m1 strip test. the assay uses a competitive colloidal gold based format. The milk sample (200 l) is added to a clear plastic reaction vessel, and used to resuspend the lyophilized reagents to a uniform pink color in the bottom of the microtiter wells. The milk is incubated briefly (5 min) at room temperature to allow the aflatoxin m1 binding protein on the gold particles to engage with any aflatoxin m1 antibiotic present in the milk. The test strip is then inserted into the sample well with the arrows pointing downward initiating capillary flow up the strip. any gold particles that are not complexed with antibiotics present in the milk will bind to the aflatoxin m1 antibiotic imprinted at the test line (t-line), forming a signal (red line) at that position. if the aflatoxin m1 binding protein on the gold particle has engaged with antibiotic present in the milk sample, the gold particle will flow past the t-line and reach the control line (c-line). for visual interpretation of the test results, t-line signal intensity that is stronger than the signal at the c-line indicates a negative result. signal at the t-line which is equal or less intense compared to the c-line indicated the presence of aflatoxin m1 antibiotics in the milk. the greater the reduction in signal intensity at the t-line, the greater the concentration of aflatoxin m1 antibiotics present in the milk.

Trimethoprim elisa test kit is a competitive enzyme immunoassay for the quantitative analysis of trimethoprim (tmp) in fish, shrimp, feed, meat (beef, chicken and pork), serum and urine. The unique features of the kit are:rapid extraction method for various sample typeshigh recovery rates (>80%)high sensitivity (0.015 ngg or ppb)quick elisa assay (less than 2 hours regardless of number of samples)high reproducibility procedure overviewthe method is based on a competitive colorimetric elisa assay. The plate wells are coated with trimethoprim (tmp) antibody. During analysis, sample is added along with the tmp-horseradish peroxidase (tmp-hrp) conjugate. If the tmp residue is present in the sample, it will compete for the tmp antibody, thereby preventing the tmp-hrp from binding to the antibody attached to the well. The resulting color intensity, after addition of the hrp substrate (tmb), has an inverse relationship with the tmp residue concentration in the sample.

Product DescriptionREAGEN Botulinum Toxin A Strip Test is a qualitative and rapid lateral flow assay designed to detect Botulinum Toxin A residues in meat, feed, milk, honey, milk powder, soil, vomit, feces, serum and water sample. This test is designed for field use or reference lab settings. The unique features of the kit are:Rapid strip test method 3 minutesHigh sensitivity 80ppbHigh reproducibility Procedure OverviewThe assay uses a double antibodies sandwich colloidal gold based format. The sample is added to the test well to allow the Botulinum Toxin A binding protein on the NC membrane to engage with any Botulinum Toxin A present in the sample. The gold particles conjugated anti-Botulinum Toxin A will bind to the drug that are bind by the Botulinum Toxin A binding protein at the Test line (T-line), forming a signal (red line) at that position. The test is negative if no colored line appears in the T area.
