Preparation of Bacteriophage λ DNA Cleaved with two Restriction Enzymes to be used as a Cloning Vector

Introduction At each end of the central stuffer fragment, a series of restriction sites arranged in opposite directions are present in replacement vectors. For instance, in EMBL3A, the order of restriction site in the left polyclonal site is SalI-BamHI-EcoRI, and that of the right polyclonal site is EcoRI-BamHI-SalI. Digestion of this type of vector with […]
