A survey of 128 biotechnology core facilities has provided data on the
finances, services, space requirements, and personnel. An average fac
ility had four full-time personnel and 7.5 major instrument systems, a
nd occupied 969 sq. ft. Average total income was $244,000/year, but an
nual user fee income was only $125,000. Typically, facilities required
substantial institutional support or grants. Cost recovery (user fee
income divided by total income) averaged 49%. During the last 5 years
user fee income, total income, and cost recovery have increased. In-ho
use charges for protein sequencing and peptide synthesis increased app
roximately 30%, while oligonucleotide synthesis charges decreased by 7
4%. The costs (charges corrected for subsidy from non-user fee income)
for most services did not significantly change, except that oligonucl
eotide synthesis costs decreased by 25% in 1992. DNA synthesis had the
highest throughput per month (116 samples), followed by amino acid an
alysis (86 samples) and DNA sequencing (67 samples). Other services av
eraged from 5 to 60 samples. DNA synthesis and purification were the s
ervices used by the greatest number of principal investigators. A numb
er of services including DNA sequencing, mass spectrometry, capillary
electrophoresis, RNA synthesis, electroblotting, and carbohydrate anal
ysis have been introduced in the last 3 years. Although these services
are characterized by high levels of methods development and non-user
runs, they are offered by twice the percentage of facilities as in 198
9, and are increasingly contributing to facility income.
