Tematika

The aim of the course is to present the theoretical and practical background of nucleic acid manipulation and vector-design. The course discusses in detail the methods and aims of nucleic acid manipulation and also the establishment of recombinant viral vectors. Participants will become familiar with the practical utilization of vectors, the genetic manipulation of cells and laboratory animals, and how e.g. a gene-therapeutic intervention is designed in the case of a monogenic recessive hematological disorder.
