Ca2+-dependent phospholipid scrambling by a reconstituted TMEM16 ion channel
Phospholipid (PL) scramblases disrupt the lipid asymmetry of the plasma membrane, externalizing phosphatidylserine to trigger blood coagulation and mark apoptotic cells. Recently, members of the TMEM16 family of Ca(2+)-gated channels have been shown to be involved in Ca(2+)-dependent scrambling. It is however controversial whether they are scramblases or channels regulating scrambling. Here we ...
متن کاملA Sensitive DNA Enzyme-Based Fluorescent Assay for Bacterial Detection
Bacterial detection plays an important role in protecting public health and safety, and thus, substantial research efforts have been directed at developing bacterial sensing methods that are sensitive, specific, inexpensive, and easy to use. We have recently reported a novel "mix-and-read" assay where a fluorogenic DNAzyme probe was used to detect model bacterium E. coli. In this work, we carri...
متن کاملA tubulin-based fluorescent polarization assay for paclitaxel.
This paper reports the development, characterization, and application of a separation-free, homogeneous, and simple to perform fluorescence polarization bioassay for paclitaxel. The bioassay is based on the binding interaction of paclitaxel to tubulin, the receptor protein on which this drug acts. The bioassay was carried out in a competitive format where the paclitaxel and a synthetic fluoresc...
متن کاملA Label-Free Aptamer-Based Fluorescent Assay for Cadmium Detection
Selective detection of ultratrace amounts of cadmium (Cd2+) is extremely important for food safety and environmental monitoring because of its toxicity and widespread use. In this work, we developed a facile, rapid, sensitive, and highly selective method for the detection of Cd2+ based on a label-free aptasensor using an unmodified double-stranded deoxyribonucleic acid-specific dye (PicoGreen)....
متن کاملOptimizing urothelial cell preparation for the human urinary micronucleus assay.
Biological monitoring of early genotoxic effects in urothelial cells using the urinary micronucleus (MNu) assay is promising for early detection of cancer, such as bladder carcinoma. But many problems are encountered, the major being the poorly differential staining of cells, particularly in women having an important amount of squamous cells. We have optimized the protocol and obtained a differ...
