The Computational Genomics Core provides neuroscientists and other Tufts investigators with resources for gene expression and genomics studies, pathways analysis and computational biology. Bioinformatics software applications, such as GeneSpring and Bioconductor for microarray analysis, are available on CNR workstations located in Stearns 328. Core users can reserve a computer by contacting Mr. Chris Parkin and signing up in the facility logbook. A web interface for the Tufts Bioconductor suite (CARMAWeb) is now available. A tutorial for CARMAWeb can be found at this link. You can learn more about the Tufts Bioinformatics Server at this link. Contact Dr. Lax Iyer or Mr. Chris Parkin with questions about core services.

The CNR
Genomics Core includes the Tufts
Expression Array Core (TEAC) which provides instruments and
expertise for gene expression studies (located on Stearns 2). There are
instruments for nucleic acid analysis (Nanodrop and
Agilent Bioanalyzer), 2 Q-PCR machines (Stratagene real-time cyclers), and Affymetrix
microarray analysis (GeneChip
system 3000).
To reserve the Affymetrix instrument, or Bioanalyzer,
please contact Mr. Chris Parkin and sign up in the appropriate facility
logbook. To use the Stratagene real-time cyclers, sign up on the calendar at Q-PCR Mx4000 and Q-PCR Mx3000P.
The current Tufts-negotiated prices
for Affymetrix gene chips can be found at
this link. Please contact Mr. Parkin for current pricing of microarray
services and use of facility instruments (Bioanalyzer and Q-PCRs).
In addition to gene profiling
services, the CNR Genomics Core subsidizes access to mass
spec services for neuroscientists (in the Tufts
Molecular Core). These and other CNR core services are subsidized
for neuroscientists through the new CNR Core
Award.
