DNA Sequencing Facility

The DNA Sequencing Facility in the department was started in 1993, with BBSRC funds, under the direction of Dr (now Professor) Peter Leadlay and subsequently equipped largely by grants held by Professor Leadlay. Since that time the Facility has developed rapidly as the ability to sequence genes has become a pervasive and essential tool in all areas of biological research. The scale of the projects tackled now ranges from the validation of single mutations in individual genes up to sequencing of entire microbial genomes. We have continually updated the equipment, in order to maximize the information obtained and to minimize turn-around time, and to make the Facility as user friendly as possible. The use of radioactive isotopes has been completely eliminated and all sequencing reactions are done by Facility staff, from the templates supplied.

Currently, sequencing is carried out on an Applied Biosystems 3730xl DNA Analyser, purchased with a BBSRC Research Equipment Award and funds generated by the Facility. This superb instrument utilizes a 96 capillary array and 96 reactions may be run in under two and a half hours, each reaction potentially giving up to 800 or more nucleotides of sequence from high quality templates. Results are usually sent by email to customers.

Facility staff have expertise in most aspects of DNA sequence analysis and can offer help and advice to both experienced researchers and to beginners. We welcome proposals for large-scale projects as well as for more routine small-scale sequencing.
