Covaris Fragmentation

The GBCF provides DNA fragmentation services using the Covaris S220 Ultrasonicator System. Nucleic acid fragmentation is applicable to many applications including DNA sequencing library preparation, chromatin shearing, tissue homogenization, cell lysis, compound dissolution, and particle micronization. Ultrasonication is favored over other fragmentation methods because DNA molecules are randomly broken with minimal bias.
