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.
Advances in EMCCD Technology: Making Imaging Less Arbitrary
Nov 16 2009
Recent advances in EMCCD technology have solved the problem of non-standardized measurement units by using the photoelectron to standardize imaging experiments.
10 Tips for Successful Sample Concentration and Buffer Exchange

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.

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.
Mechanisms of plasticity in simple taxis behaviors in Drosophila
Nov 8 2009
Like the proverbial moth drawn to the candle flame, the fruit fly Drosophila also stereotypically approaches light sources. This positive phototaxis is the archetypal example of hard-wired input-output behaviors.

Involvement of ceramide in ischemic tolerance induced by preconditioning with sublethal oxygen-glucose deprivation in primary cultured cortical neurons of rats.
Feb 25
The complex molecular cascades of ischemic tolerance in brain cells remain unclear. Recently, sphingolipid-related metabolite ceramide has been implicated as a second messenger in many biological functions, including neuronal survival and death. The present study, therefore,...
Social intelligence and academic achievement as predictors of adolescent popularity.
Feb 24
This study compared the effects of social intelligence and cognitive intelligence, as measured by academic achievement, on adolescent popularity in two school contexts. A distinction was made between sociometric popularity, a measure of acceptance, and perceived popularity, a...
Novel HAX1 gene mutations associated to neurodevelopment abnormalities in two Italian patients with severe congenital neutropenia.
IgA nephropathy in two patients with Sjögren's syndrome: one with concomitant autoimmune hepatitis.
Feb 22
Concurrent glomeruli and liver involvement in patients with Sjögren's syndrome (SS) has seldom been reported. Meanwhile, IgA nephropathy (IgAN) associated with SS is not as common as other types of glomerulonephritis, such as membranoproliferative glomerulonephritis (MPGN) and...
