A survey of nucleic acid services in core laboratories.

Core facility services related to DNA synthesis and sequencing were surveyed by the Association of Biomolecular Resource Facilities. Responses from 85 facilities offering DNA synthesis and 37 facilities offering DNA sequencing were obtained. Data on instrumentation, volume, number of users, cost, methodology and a number of other criteria were obtained. The volume of work performed by these centralized core facilities was quite substantial (combined synthesis output of 4 million bases per year and a combined sequencing output of 35 million bases per year). The large number of users supported by these facilities and the high sample throughput make these core resource facilities good indicators of technological trends.
