Color variations of anthraquinone and azo reactive dyes on cellulose caused by nitrogen oxides under wet conditions

Development of polyclonal antibody-based indirect competitive enzyme-linked immunosorbent assay for sodium saccharin residue in food samples

“…The samples containing the 6-ASA-BSA and 6-ASA-OVA displayed a distinct pattern of absorbance reflecting properties of the former free molecules. We noted that there was a red shift of the absorption max which maybe caused by the amino of hapten was conjugated to the ortho-atom or ortho-atom of phenolic group carrier protein by diazotised reaction (Okada, Sugane, Watanabe, & Morita, 2008). Taken together these data indicated that the artificial antigens were synthesised preliminarily and we subsequently used them to generate polyclonal antibodies as described in Section 2.…”
