Size-Exclusion Chromatography for Purification of Biomolecules

Dec 2

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

Dec 2

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

Dec 2

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.

Nucleic Acid Decontamination with the ExitusPlus Technology

Dec 2

Using new methods that detect extremely low levels of DNA molecules, researchers investigated the molecular mechanism of action of various commercially available DNA decontamination reagents. They found that when using high concentrations of DNA and short incubation times, none of the conventional reagents destroyed DNA molecules efficiently, despite their corrosive or even toxic properties.

Attention Deficit & Hyperactivity in a Drosophila Memory Mutant

Nov 9

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

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.

Live cell imaging of mutant and wild-type GABA-A receptor trafficking using a novel reporter protein

Nov 8

Efficient signaling in the brain requires precise regulation and targeting of cell surface ion-channels. Mutations in these channels associated with inherited diseases can cause improper targeting and reduced surface expression.

ADP-Glo™: An Ideal Approach to Monitor the Activity of Protein Kinases and Beyond

Oct 16

Because of its versatility (alltypesofsubstrates), robustness (Z’>0.8), rapidperformance, and its ease of use, the luminescence based Kinase Glo® assay platform has gained wide acceptance in many drug screening programs for protein kinase inhibitors.

PKA-Mediated Golgi Remodeling During cAMP Signal Transmission.

Dec 18

Cyclic AMP (cAMP)-dependent protein kinase A (PKA) is part of the set of signaling proteins that are stably associated to the cytosolic surface of Golgi membranes in mammalian cells. In principle, Golgi-associated PKA could participate in either signal transduction events...

Depression, traumatic stress and interleukin-6.

Dec 18

BACKGROUND: Recent evidence indicates that various types of interactions between nervous and immune system are important in pathogenesis of depression. These findings show that a significant role in developing depression play pro-inflammatory cytokines that may mediate its...

A short duration of untreated illness (DUI) improves response outcomes in first-depressive episodes.

Dec 18

BACKGROUND: Few studies have addressed the implication of the duration of untreated illness (DUI) on the clinical outcome of mood disorders. Although not focusing on DUI, previous findings suggest that the longer it takes to start appropriate treatment, the worse will be the...

TSH Receptor and Thyroid-Specific Gene Expression in Human Skin.

Dec 18

Experimental evidence suggests that in autoimmune thyroid diseases (AITDs) the skin is a target of autoantibodies against thyroid-specific antigens; however, the role of these autoantibodies in skin alterations remains unclear. To gain insight into the function of nominally...

Prokariotic Cell Collection in Denmark

Nov 6

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.
