Published: October 2014

A novel technique for protein immobilization onto CrAsH-modified surfaces is presented. This approach enables an efficient, reversible and fluorogenic immobilization of proteins. Moreover, expressed proteins can also be directly immobilized from cellular lysates without prior purification. The immobilized proteins are suitable for protein-protein interaction studies and the fluorescence enhancement upon immobilization can be employed for the direct detection of the immobilized protein without the need for secondary detection methods.

Biolayer interferometry (BLI) is an optical sensor-based analytical method primarily used for analyzing interactions between biomolecules. In this study, we explored the application of BLI to observe the cleavage reaction of glutathione S-transferase (GST)-tagged fusion protein by human rhinovirus (HRV) 3C protease on a BLI sensor as a new application of the BLI method. The soluble domain of the Tic22 protein from was expressed and purified as a GST-tagged fusion protein, GST-Tic22, in .

Until recently, the lack of three-dimensional visualisation of whole cells at the electron microscopic (EM) level has led to a significant gap in our understanding of the interaction of cellular organelles and their interconnection. This is particularly true with regard to the role of the endoplasmic reticulum (ER). In this study, we perform three-dimensional reconstructions of serial FIB/SEM stacks and anaglyphs derived from volume rendering, cryo-scanning electron microscopy (cryo-SEM) and state-of-the-art electron microscopy immobilisation and imaging techniques.

Aim: Chronic stress elevates blood pressure, whereas regular exercise exerts antistress and antihypertensive effects. However, the mechanisms of stress-induced hypertension and preventive effects through exercise remain unknown. Thus, we investigated the molecular basis involved in autonomic blood pressure regulation within the amygdala.

Background: Glioma accounts for 80 % of all malignant primary brain tumors with a high mortality rate. Histopathological examination is the current diagnostic methods for glioma, but its invasive surgical interventions can cause cerebral edema or impair neural functioning. Liquid biopsy proves to be an efficient method for glioma detection.

α-Amylases, constituting a significant share of the enzyme market, are mainly synthesized by the genus Bacillus. Enzymes tailored for specific industrial applications are needed to meet the growing demand across a range of industries, and thus finding new amylases and optimizing the ones that already exist are extremely important. This study reports the successful expression, characterization and immobilization of P.
