The PCR-produced linear DNA is expected to accelerate vaccine production.
Applied DNA Sciences and Takis Biotech have designed four Covid-19 vaccine candidates to help protect against the novel coronavirus.
The companies plan to manufacture the DNA vaccine candidates using PCR-based DNA (LinearDNA) manufacturing systems for preclinical testing in animals.
Last month, Applied DNA Sciences subsidiary LineaRx expanded its collaboration with Takis Biotech for the preclinical development of a LinearDNA Covid-19 vaccine.
The vaccine candidates were created using the structure of the Spike protein that allows the coronavirus to bind and infect the host cells.
