Sample Type:Chicken,liver,honey,milk,egg,urine,serum,pork,and other samples.Intended Use:This BioAssay kit allows for the in vitro quantitative determination of Sulfathiazole concentrations in chicken,liver,honey,milk,egg,urine,serum,pork,and other samples.Sensitivity:0.4ppbRange:0.4-32.4ppb. The standard curve concentrations used for the ELISA’s were 32.4ppb,10.8ppb,3.6ppb,1.2ppb,0.4ppb,0ppb.Precision:Intra-assay: CV%<10%Inter-assay: CV%<10%Test Principle:This BioAssay employs the indirect competitive inhibition enzyme immunoassay technique. The coupling antigen is pre-coated on the micro-well stripes.( A Sulfathiazole conjugate has been pre-coated onto a microplate) Then the Sulfathiazole in the sample and the coupling antigen pre-coated on the micro-well stripes compete for the anti-Sulfathiazole antibody. After the addition of the enzyme conjugate,the TMB substrate is added for coloration. The optical density (OD) value of the sample has a negative correlation with the Sulfathiazole in the sample. This (OD) value is compared to the standard curve and the Sulfathiazole concentration is subsequently obtained.Kit Components:Assay plate,1x96TStandard,6x1mlHRP-conjugate,1x7mlAntibody,1x10mlSubstrate A,1x7mlSubstrate B,1x7mlStop Solution,1x7mlWash Buffer,2x20ml (20Xconcentrate)Redissolving Solution,3x15ml (2Xconcentrate)Storage and Stability:Store powder at 4°C liquid at -20°C.
