Positive and Negative Selectable Markers
- Positive selectable markers are selectable markers that confers selective advantage to its host organism. An example would be antibiotics resistance, which allows the host organism to survive antibiotics selection.
- Negative selectable markers are selectable markers that would eliminate its host organism upon selection. An example would be thymidine kinase, which would make the host sensitive to ganciclovir selection.
