I know everything I am looking for is here, watch movies, watch series, education, games, exams, news, current events and many more.
“#Scientists develop low-cost chip to detect presence and quantity of COVID-19 antibodies” The antibody testing platform, developed by researchers from the Micro/Bio/Nanofluidics Unit at OIST. Credit: OIST Robust and widespread antibody testing has emerged as a key strategy in the fight against SARS-CoV-2, the virus responsible for the COVID-19 pandemic. However current testing methods are…
“#Detecting small amounts of virus in early infections” High-pressure preconcentration devices for increasing the potency of biofluid samples to be used with point-of-care assays for detection of pathogens, such as flu or coronavirus. Credit: Amy Drexelius Diagnostic devices that are used at home or in doctors’ offices are often not sensitive enough to detect small…
“#Chemists expand genetic code of E. coli to produce 21st amino acid, giving it new abilities” Rice University researchers introduced noncanonical amino acid building blocks into proteins in living cells, pioneering a powerful tool for investigating and manipulating the structure and function of proteins. The resulting unnatural organism, a strain of Escherichia coli bacteria, is…
“#Multisample technique to analyze cell adhesion” The new assay developed at KAUST is a fluorescent multiplex cell rolling assay that uses unique fluorescent tags to label up to seven cell population types. Credit: © 2020 Elham Roshdy King Abdullah University of Science and Technology researchers have developed a robust and efficient method of examining the…
“#Templating S100A9 amyloids on Aβ fibrillar surfaces revealed” AFM image of the amyloid templating of S100A9 fibrils on the surface of Aβ fibrils. Credit: Jonathan Pansieri A research team lead by Ludmilla Morozova Roche at Umeå University, Sweden, has provided the mechanistic insight into protein co-aggregation in Alzheimer’s disease. The templating mechanism of S100A9 amyloids…
