HOCHMOLEKULARGEWICHTIGE DNS-PRÄPARATE ZUR ELEKTROPHORETISCHEN BESTIMMUNG VON NUKLEINSÄUREN.

摘要

The invention provides high molecular weight DNA length standards useful for sizing very long DNA molecules and methods for producing such standards. In a preferred embodiment, the invention provides a mixture of T4 DNA concatemers that forms a DNA "ladder" having rungs differing by at least 0.17 Mb (Megabases) in length upon gel electrophoresis and methods for producing and using such compositions.
