Packagene®LambdaDNAPackagingSystem
Packagene® Lambda DNA Packaging SystemThe Packagene® Lambda DNA Packaging System is derived from the unique one-strain host system (Rosenberg). The System is easy to use because it contains all the components and buffers needed to perform the packaging reaction in a single tube. Only the addition of substrate DNA is required.
