Oligonucleotides were synthe-sized by Gibco-BRL Life Technologies. Sequences were aligned using GCG (Genetics Computer Group) PILEUP program (with a gapweight of 5. Purifying Large E.

The flow rate was 0. Restriction enzyme sites were "forced" for the C1100T and the T-2854G by incorporating single-base changes into one of the pair of primers used in the PCR reaction. The present invention relates to a method for producing long DNA constructs, particularly artificial chromosomes, and vectors usable for this purposes, as well as a method of providing large DNAs, particularly BACs or PACs. Validation of radioactive methods in the quality control of DNA restriction enzymes. ‘I’wo additional units per pg were added to the reaction, and incubation was continued. To avoid Vim+ revertants, SW13Vim- cells were used only at passage numbers less than 12 following an initial selection process and were periodically tested for the presence of vimentin.
