 | | Imaging flow cytometry enhances particle detection sensitivity for extracellular vesicle analysis www.millipore.com > The study of extracellular vesicles (EVs) has evolved into a compelling field of intercellular communication and pathophysiology research. The submicron size of EVs and the complexity of the biofluids in which they are suspended confound their analysis by traditional light microscopy or flow cytometry. Observation and quantitation of EVs have been achieved with Amnis® imaging flow cytometers (IFCs) with reduced volumes and sample preparation times, suggesting an auspicious role for IFCs in the advancement of EV biology.

 | | Screening and quantification of the tumor microenvironment with micro-ultrasound and photoacoustic imaging www.visualsonics.com > The family of Vevo® Imaging Systems from FUJIFILM VisualSonics, Inc. is leading to translational breakthroughs in the understanding of cancer progression and therapy. More specifically, high-frequency ultrasound and photoacoustic imaging of orthotopic and patient-derived xenograft (PDX) models of human cancer have empowered researchers in the past decade, with key translational findings on tumor growth and microenvironment and in response to new and existing cancer therapies. This Application Note focuses on the deep-tissue-imaging capabilities of micro-ultrasound and photoacoustic imaging that contributed to these translational findings..

 | | GelApp: Mobile gel electrophoresis analyser www.a-star.edu.sg > GelApp is a free mobile application that automatically detects and quantifies gel electrophoresis bands for "on-the-go" gel documenta-tion. It facilitates quantitative biological research by providing more accurate band sizes.Through the novel implementation of Gabor filters, faint bands can be better detected from noisy backgrounds than conventional image analysis methods. Plotting the marker standard as a logarithmic (log) graph, the sample band sizes are calculated more accurately. Combined, these features help increase the productivity and accu-racy of gel electrophoresis analysis that every scientist can carry in their pockets.

 | | Exploring Protein Phosphorylation with RayBio® Antibody Arrays and ELISAs www.raybiotech.com > Phosphorylation is arguably the most important regulatory mechanism in biological systems, directing both the activity and subcellular localization of many key signaling proteins. Phosphorylation is often detected by isotope labeling or by 2D gel and mass spectrometry analyses. Both methods are highly sensitive. However, because of the high equipment cost and labor required for mass spectrometry, and the special isotope handling and disposal required for radiolabeling, phospho-specific antibodies are generally the more preferred tool for detection of protein phosphorylation. ELISAs can be designed to rapidly and inexpensively detect phosphorylation-induced conformational changes in a specific protein, allowing many samples to be tested in parallel. Alternatively, phospho-specific antibodies can be multiplexed into an array format, allowing the simultaneous detection of multiple target phospho-proteins. Using these powerful tools, researchers can accomplish either high throughput detection of a specific activated protein in multiple samples, or detect phosphorylation signatures through parallel detection of many related phospho-proteins.
