Accelerated
Solvent Extraction With Acid Pretreatment for Improved Laboratory
Productivity |
by Brian Dorich, Eric Francis, Brett
Murphy, Bruce Richter, and Sheldon Henderson
|
Sample preparation, specifically solvent extraction, is an important
beginning step in the analytical process. If the extraction procedure
is incomplete, the results are inaccurate analyses or poor recoveries.
Analysts have used an array of solvent extraction techniques ranging
from Soxhlet, shaking, sonication, and blending. Accelerated solvent
extraction (ASE®) technology is a flow-through solvent extraction
system that helps increase productivity and sample throughput
while reducing preparation cost and providing a platform for automation.

In
Situ Gas Heating and Real-Time 3-D Imaging Using a Transmission
Electron Microscope |
by Xiao Feng Zhang
|
In
situ atomic resolution imaging with gas injection and sample heating,
and realtime three-dimensional structural and chemical characterizations
are important features of the Hitachi H-9500
300 kV transmission electron microscope (TEM) ( Hitachi
High Technologies America, Inc., Pleasanton, CA). In
situ gas environmental transmission electron microscopy (E-TEM)
has been well recognized for its irreplaceable role in performing
dynamic observation. The purpose of the E-TEM is to introduce
gas into the specimen chamber of a TEM to study the gas–solid
interactions between sample and gas. Since TEM works at high vacuum,
gas is typically introduced into the microscope in two ways. The
first method is to seal a sample in an environmental cell (E-cell)
confined by electron transparent windows. The advantages of this
window-type E-cell include simple design and low cost, but atomic
resolution is difficult to achieve, and heating the sample is
risky because the window materials may be damaged at elevated
temperatures, causing gas to leak into the microscope column.

Independent
technical report evaluates protein precipitation microplates |
Advertisement |
|
A technical report based upon an independent in-depth
evaluation of currently commercially available protein
precipitation microplates is available from Porvair Sciences Ltd.
The use of protein precipitation as a method for sample preparation
is widely used within the pharmaceutical research community. Consequently
the need to automate the technique, to save technician time, has
spurned a new generation of special multi-well filtration microplates
adaptable for automated sample preparation using liquid handling
equipment.
Undertaken by a drug metabolism department of a major multinational
pharmaceutical company, the evaluation concluded that the p3 microplate
from Porvair Sciences represents the current benchmark in protein
precipitation technology.

A
Real-Time Interface of Liquid Chromatography and Infrared Spectroscopy |
by Tom Kearney and James L. Dwyer
|
The analysis of multicomponent samples usually involves
two separate laboratory techniques: 1) fractionation of the sample
into its discrete components, and 2) identification/quantification
of components. Chromatography, in particular liquid chromatography,
is the most commonly used fractionation technique. Spectrometry
in its various forms is prevalent for identification.

Evaluating
Candidate Lead Compounds by Rapid Analysis of Drug Interactions
with Human Serum Albumin |
by Vered Bronner, Oded Nahshol,
and Tsafrir Bravman |
Human
serum albumin (HSA) plays a fundamental role in the transport
of drugs, metabolites, and endogenous ligands. Binding to HSA
controls the free, active concentration of a drug, provides a
reservoir for a long duration of action, and ultimately affects
drug absorption, distribution, metabolism, and excretion (ADME),
making HSA binding a key parameter in evaluating candidate lead
compounds during drug design. A broad range of approaches has
been used to study drug–protein binding, including equilibrium
dialysis, filtration, centrifugation, and chromatography. However,
the resolution, reproducibility, and throughput of these methods
are limiting.

The dual needle's ability to continually sweep the headspace for concentration on the optional adsorbent trap or at the analytical column give the user the flexibility to increase the sensitivity of the analysis when needed. Other novel standard features such as the ability to make both traditional time based injections and traditional fixed loop injections within the same schedule, 90 position carousel, constant heat mode, multiple headspace extractions, and bulk sampling make the Markelov HS9000 the most versatile headspace sampler available for a wide variety of applications.

A
Microfluidic Approach to Patch-Clamp-Based Ion Channel Safety
Testing |
by Fredrik Pettersson, Christer
Johansson, Susanne Braum, and Jon Sinclair |
The
development of patch-clamping, whole-cell, and single-channel
recording has made in-depth studies of ion channels possible in
a wide variety of preparations. An important aspect of ion channel
studies is safety testing, since it has been found that certain
drugs affect ion channels governing heart function. The activity
of many ion channels is temperature dependent; thus it is important
to study ion channels at different temperatures. Temperature is
especially important in safety screening applications in which
variations from physiological conditions could lead to misleading
results and erroneous conclusions. To support temperature-controlled
safety screening, the Dynaflow ® temperature control
system ( Cellectricon, Gothenburg, Sweden) was
developed. The system combines the Dynaflow DF-8 Pro II chip with
its controlled solution exchange and low compound consumption
with a stage that provides precise temperature control.
