    摘要: The present application is directed to a method for performing a bisulfite reaction to determine methylation positions in a nucleic acid, i.e. methylated and non-methylated cytosines. In this method, the nucleic acid is bisulfite treated and is bound to a solid phase when an alkaline solution is added for desulfonation and elution of the nucleic acid from the solid phase. The nucleic acid can be amplified in an additional step. The solid phase is preferably a material comprising glass or silica, more preferably a glass fleece, glass membrane or a magnetic glass particle. Further, several uses of the alkaline solution for bisulfite treatment are disclosed and a kit containing a bisulfite reagent, a solid phase and an alkaline solution.

    摘要: An immunological method for the determination of triazine and triazine derivatives by a competitive immunoassay in which the sample and labelled atrazine compete for a polyclonal antibody which is bound to a solid phase before, during or after the immunological reaction, the immunological complex binds to the solid phase, the solid phase and unbound labelled atrazine are separated and the label in the solid or liquid phase is determined as a measure of the content of triazine and triazine derivatives, which is characterized in that polyclonal antibodies which were obtained by immunization with a 4-alkylamino-S-triazine are used and a conjugate of a label and 4-amino-S-triazine which is bound to the label via the 6 position is used as the labelled atrazine. Triazine and triazine derivatives can be determined simultaneously using this method.
