Multi-Parametric Cellular Analysis
Mar 23
Flow cytometers perform a variety of multi parametric applications and have been used for an expanding set of cell analysis applications over the past forty years.
Maintaining a Healthy Cell Culture Environment
Investing in best practices and products at the beginning of any experiment is the most time- and cost-effective way to approach cell culture.
Publishing Data That Conform to the MIQE Guidelines
Jan 22
Minimum information for publication of Quantitative Real-Time PCR Experiments (MIQE) guidelines help researchers design qPCR experiments.
Calibration Free Analysis to Measure the Concentration of Active Proteins
Nov 23 2009
An SPR-based method, Calibration Free Concentration Analysis can be used to accurately determine the concentration of active protein in a sample, relating to the specific binding activity of the protein, and without the need for a standard.
Advantages of Monolithic Laser Combiner Technology in Confocal Microscopy Systems
Jan 6
Fluorescence microscopy techniques require a reliable light source at the desired wavelength or wavelengths, with minimal downtime for maintenance and alignment. Lasers are a popular light source, although the alignment and upkeep of laser combiners is a time-consuming prospect for many users.
Size-Exclusion Chromatography for Purification of Biomolecules
Dec 2 2009
Size-exclusion chromatography (SEC) is a popular method to separate biomolecules based on their size. Primarily, it is applied to the separation of biopolymers such as proteins and nucleic acids, i.e. water-soluble polymers.
Improving Separation During Electrophoresis
SeparateIT gels represent a novel gel matrix for DNA electrophoresis. Gel polymers are arranged in a conceptually different way, in accordance with a new theoretical model of gel electrophoresis.
Improving Quality of ELISA
Using ready-to-use ELISA kits from manufacturers is easy and convenient. Sometimes however, home-made ELISA is required because there is no kit available with the right antibodies or the characteristics of the available kits such as their limits of detection are not appropriate.
Using the Tecan Genesis Workstation to Automate a Cytometric Bead Array (CBA) Immunoassay
Mar 11
The poster describe the process involved in automating a Cytometric Bead Array (CBA) immunoassay developed to measure relative concentrations of serum antibodies against Tetanus (TT), Sperm Whale Myoglobin (SWM) and Keyhole Limpet Hemocyanin (KLH) in KLH-immunized volunteers.
Ensuring Quality in Assays Performed with Automated Liquid Handlers
Feb 2
The focus of this presentation is to highlight the need of ensuring quality in important assays performed with automated liquid handlers. Nearly all assays performed within a laboratory are volume-dependent. In turn, all concentrations of biological and chemical components in these assays, as well as the associated dilution protocols, are volume-dependent. Because analyte concentration is volume-dependent, an assay’s results might be falsely interpreted if liquid handler variability and inaccuracies are unknown or if the system(s) go unchecked for a long period.
Inkjet System for Protein Crystallography
Feb 1
X-ray crystallography is used routinely by scientists to obtain the three dimensional structure of a biological molecule of interest.Such information can be used to determine how a pharmaceutical interacts with a protein target and what changes might improve functionality. However, the crystallization of macromolecules still remains a serious hindrance in structural determination despite impressive advances in screening methods and technologies.
Attention Deficit & Hyperactivity in a Drosophila Memory Mutant
Nov 9 2009
Action selection is modulated by external stimuli either directly or via memory retrieval. In a constantly changing environment, animals have evolved attention-like processes to effectively filter the incoming sensory stream. These attention-like processes, in turn, are modulated by memory. The neurobiological nature of how attention, action selection and memory are inter-connected is unknown. We describe here new phenotypes of the memory mutant radish in the fruit fly Drosophila.
Interparental conflict and academic achievement: an examination of mediating and moderating factors.
Mar 27
Using a risk and resiliency theoretical framework, the association between interparental conflict and academic achievement was examined. The sample consisted of 2,297 6th grade youth with a mean age of 11.92. Participants were mostly European American (81.8%) and 52% were...
New frontiers in gut nutrient sensor research: monosodium L-glutamate added to a high-energy, high-protein liquid diet promotes gastric emptying: a possible therapy for patien...
Mar 26
Functional dyspepsia is a clinical syndrome that features abdominal symptoms centered in the upper abdomen without an organic basis. Three possible mechanisms of gastric dysfunction could be related to functional dyspepsia: 1) delayed gastric emptying, 2) impaired gastric...

Prokariotic Cell Collection in Denmark
Nov 6 2009
I would like to know about a prokariotic cell collection in Denmark. Is there a cell bank in this country? I need a Lactobacillus strain for a fermentation assay and this information about the bank is very helpful for me.
