Gene Selection Antibiotics

Transfection is a process of introducing DNA or other nucleic acids into eukaryotic cells. Foreign DNA can be introduced into eukaryotic cells by chemical-based or physical methods which include electroporation and sonoporation. To ensure DNA has integrated into the cell's genome, a selective marker is co-transfected with the desired gene which usually confers resistance to a selective agent or antibiotic. Selective stress is applied to transfected cells by using a selective agent or selection antibiotic. Only cells that contain the desired gene along with a resistance gene will grow and survive in the presence of a selective agent. Frequently used selection antibiotics include G418, hygromycin b, neomycin, and puromycin.
