The Molecular
Toxicology Laboratories comprises four main
laboratories covering some 2,800sq. ft. within the
Department of Biological Sciences at CSULB. The main wet laboratory contains much of the equipment
necessary for wet bench-work involving sample
preparation and analysis.
The
facility is equipped with three fume hoods and two
Barnstead Nanopure™ reagent water systems for the
production of 18 megohm ultra-pure water free of
trace metal contamination and pyrogens. Other
equipment in this laboratory includes 2
dual-gradient HPLC’s (Two Beckman™ system 32
Karat 126 solvent delivery modules with two168
Diode Array UV/VIS detectors) and a quaternary
Waters™ HPLC with a 484MS tunable detector.
The
laboratory is also equipped with 2 D SDS-PAGE and
TLC, various
homogenizers, a UV-visible spectrophotometer, a
lyophilizer, low and medium speed centrifuges and
auxiliary equipment such as pH meters and
balances. Two Lab-Line environmental chambers with
full sub-ambient temperature control are available
for maintaining animals and cells in radioactive
media.
The
ICP-MS room houses a HP™ 4500 ICP-MS and a Perkin
Elmer™ 6100 DRC, dual quadrupole ICP-MS with hydride
generation facility and a flow injection analysis
system. The
room was designed specifically to meet class 1000
specifications and to be metal free.
It covers an area of 450 sq.ft which is
divided into 3 functional areas: an air locked
vestibule; the instrument area; and the wet
laboratory.
All
flooring is composed of a hermetically
seam-sealed, chemically resistant, polymer. The
wet preparation section has four Teflon coated
benches that are provided ultrapure from a Barnes
water system that receives house water that has
been purified by reverse osmosis.
A quartz still, located in a Teflon-lined
chemical hood, is available for redistillation of
mineral acids. An additional laminar flow hood is
available for sample preparation.
The second bench houses 6 mineral acid
baths for cleaning and decontaminating glassware.
The
final two benches are mobile and are designated
for sample preparation and transportation to the
instrument.
The third laboratory is dedicated to
organic two HP-VG Trio GC-MS’s. Ancillary
equipment for the rotor evaporation and microwave
digestion of samples are also located in the fume
hood in this laboratory.
A heavy duty, industrial type, -80oC
freezers with liquid CO2 backup and a
chest style –20oC refrigerator
together with 3 conventional refrigerators are
located in this laboratory for sample storage.
The
fourth laboratory is used primarily for
radioisotope studies and houses a Beckman™ liquid
scintillation counter and a LKB CompuGamma™
counter with the ability to deconvolute 4 isotopic
channels. Other
equipment available outside of the laboratory
include a Beckman ultracentrifuge, a cell culture
facility with a sub-ambient
CO2, humidity and temperature
controlled Forma Scientific incubator inverted
scopes, laminar-flow hoods.
Other
equipment available for use include a Beckman
DU-640B UV/Vis Spectrophotometer, Savant Speed vac
System with cryovacuum system, Pharmacia FPLC
Protein Separation System, Northern Blotting, and
PCR thermo-recyclers and automated DNA sequencing
systems.
Other
equipment associated with the molecular toxicology
facility include a JEOL™ 1200EXII Transmission
electron microscope with a CCD camera and an AMRAY™
1830T SEM with full analytical capability
including a backscatter detector, cathode-illuminescence
and EDX and WDX detectors.
