A high-throughput plasmid DNA preparation method.

Genome projects require a high-throughput method for DNA template preparation, which traditional protocols can rarely provide. We introduce here a new protocol for plasmid and cosmid DNA preparation based on alkaline denaturation in a 96-well format. The essential improvement made in this protocol on previous 96-well preparation includes the purification by Pro-Cipitate in 96-well microfilters. The yield and quality of DNA are sufficient for restriction digestion, radioactive sequencing, and automated fluorescent sequencing. It is also significantly more cost-effective than several of the commercial mini-prep kits.

Structural analysis of the mouse T-cell receptor Tcra V2 subfamily.

Cosmid clones containing T-cell receptor Tcra V2 subfamily gene segments have been isolated from a BALB/c cosmid library and subjected to DNA sequence analysis. The V gene segments in the Tcra V2 subfamily differ from each other by 3%-7% at the nucleotide level and 5%-16% at the amino acid level. T-cell receptor Tcra V2 gene segment polymorphisms have been identified in the B10.PL and PL/J mouse strains with a Tcra V2 subfamily-specific probe. These V gene segment polymorphisms may cause the differential Tcra V gene usage in induced experimental allergic encephalomyelitis between B10.PL and PL/J mice.
