Process and apparatus for forming a dry DNA transfer film, a transfer film product formed thereby and an analyzing process using the same

摘要

Pivotable jigs or tables facilitate inversion or reciprocation of one or more well plates relative to a dry DNA transfer sheet to effect deposit of DNA gene solution as spaced spots on the surface of the transfer media sequentially to produce after drying of the DNA gene solution spots transfer of the dry DNA material from the spots by forcible impact or rubbing pressure through a printing mechanism of minute dry DNA dots onto a test substrate such as a glass plate for subsequent analysis optically via fluorescent labels to determine the presence or absence of mutations and a further identification of the mutation itself.
