Molecular and Cell Biology Facility Core
NYU NIEHS Center
Molecular and Cell Biology Facility Core
Purpose
Research in the area of environmental health sciences requires multidisciplinary
approaches, utilization of new, accurate and highly sensitive molecular
techniques and the use of state-of-the-art instruments that allow researchers
to obtain, store, quantitate, and organize experimental molecular biology
data. Since cutting-edge, high-throughput instruments are expensive
and not affordable to individual investigators, the Molecular and Cell
Biology Facility Core maintains and upgrades this essential dedicated
equipment for shared use by molecular biology researchers. Also, since
the most current molecular approaches require considerable training before
their routine implementation, this Facility Core provides expert instruction
and consultation services on the use of these techniques. In order to
maintain cutting-edge status, the Facility Core continues to acquire
new state-of-the-art, high cost equipment through competitive and institutional
funding sources. To further support the molecular biology research
in the Center, the Molecular and Cell Biology Facility Core operates
an on-site commercial store with well-stocked freezers containing a wide
variety of discounted restriction and modifying enzymes, and DNA sequencing
and PCR reagents and kits. Since many Center researchers who are
active in the area of molecular biology use cultured cells in their research,
this Facility Core also provides highly discounted tissue culture media
and fetal bovine serum at considerable cost savings compared to commercial
suppliers. The Facility Core offers consultation regarding preparation
of specialized tissue culture media, and identification of less expensive
or alternate media or serum substitutes.
Personnel
Catherine B. Klein, Ph.D., Director, has over 25 years experience in
mammalian cell culture and molecular biology. As Facility Core
Director, she interacts with funded investigators to coordinate the efficient
use of all available services. Dr. Klein assumes overall responsibility
for the operations of the entire facility and in that capacity is the
direct supervisor of its technical staff. For the molecular biology supplies
center and the Media Preparation Center, Dr. Klein provides quality control
and sterility assurances.
Isaac Wirgin, Ph.D.,Co-Director, is an experienced
molecular/population biologist (17 years at NYU) with research interests
in transcriptional regulation of gene expression in toxicant-exposed
cells and organisms and population genetics. Dr. Wirgin has a long
history of identifying intrinsic and extrinsic factors that impact gene
expression at the mRNA level. Dr. Wirgin is responsible for overseeing
the daily operations of all molecular biology equipment within the Core,
including technical support, interactions with companies for contractual
negotiations, as well as maintenance and service of all instruments.
Dr. Nirmal Roy, Ph.D., is the Molecular Biology Consultant for the Molecular
and Cell Biology Facility Core. He is a Research Assistant Professor
of Environmental Medicine with more than 20 years of experience in molecular
and cellular biology including the cloning of various toxicological relevant
genes from fish models (cytochrome P450s and AHR pathway molecules).
Dr. Roy advises on the use and provides the appropriate negative, positive,
and normalization controls for all hybridizations. He assists in the
evaluation of the printing success including analyses of spot morphometry,
hybridization potential of probe, and evaluation of background on all
slides. He also advises on use of the scanner to obtain, evaluate and
initially organize hybridization data. Dr. Roy is responsible for
advising new users on sequencing on the automated DNA sequencer, and
he responsible for the preparation and labeling of DNA targets to be
used on Affymetrix GeneChip and custom microarrays.
Lorraine Maceda, is an experienced molecular biology technician for
the past 15 years and serves as Molecular Biology Technician for the
Facility Core. Ms. Maceda has many years of experience in genotyping
and has optimized use of the DNA sequencer for DNA fragment/microsatellite
analysis. Ms. Maceda, under the supervision of Co-Director Dr.
Wirgin, provides on-site technical advice to research investigators,
maintains contacts with service people, and is responsible for the routine
weekly maintenance of the PhosphorImager, fluorescent microplate reader,
Alpha Innotech Imager, Kodak developer, Kodak camera, DNA sequencer,
and microarray spotter/scanner.
Linda Tomlinson, is the Facility Core technician responsible for all
dishwashing services related either to media preparation or lab maintenance,
the weekly maintenance of the Millipore water systems, the ordering of
supplies and ingredients required to provide all these services, the
daily scheduling of autoclave use, and oversight of the operations and
maintenance of the autoclave and dishwashing equipment. She has
over ten years experience at NYU performing these duties.

molecular biology imaging instruments including a PhosphorImager, Fluorescent
Microplate reader, AlphaImager, and Kodak film developer. The Facility
Core also helps to develop new methods employing this equipment.
4) consultation and training on commonly used molecular biology techniques
including, but not limited to, Northern, Southern, and Western blots,
real-time PCR, RT-PCR, and gel mobility shift analyses. This Core
will also aid Center investigators in use of software available in the
Genetics Computer Group (GCG) package.
5) basic molecular and cell biology research and laboratory support
including (a) an "on-site" commercial supply of discounted
molecular biology enzymes and reagents, (b) freshly prepared, highly
discounted tissue culture media, buffers, and serum, and (c) cost efficient
MilliQ water, dishwashing, and autoclaving services.
Operational Policies
The operational policies of the Molecular and Cell Biology Facility
Core are as follows: The Imaging Center is open seven days a week, and
is available to all investigators who have completed training and do
not need supervision. Qualified users include any investigator
who is entitled to receive research funding via NYUSOM. Those individuals
requiring assistance can be assisted by the Facility Core technician,
according to the schedule posted in the Imaging Center. Investigators
reserve a block of time (30 min- 4 hr) in advance, recorded in a logbook
for the use of each instrument. Each new investigator will have
their own password, and a computer program will automatically calculate
individual investigator use for our records. All Center members have
access to the Laboratory Supplies Unit on a first come, first served
basis, during usual working hours (8AM to 5 PM, M-F). All operations
of the Genotyping, Microarray, and Imaging Units of the Facility Core
are carried out by personnel with over 20 years experience in molecular
biology according to detailed protocols established by the facility Co-Director
Dr. Wirgin and Molecular Consultant, Dr. Roy, after consultation with
the individual investigators. Written protocols are available to
all investigators upon request and on the Web. A user committee comprised
of several active molecular biology researchers including Drs. I. Wirgin,
C. Klein, T. Gordon, C. Huang, N. Roy, M.-s. Tang and R. Shore reviews
the daily operations and future directions of this Facility Core.
