BACKGROUND The loop-mediated isothermal amplification (LAMP) assay, with its advantages of simplicity, rapidity and cost effectiveness, has evolved as one of the most sensitive and specific methods for the detection of a broad range of pathogenic microorganisms including African trypanosomes. While many LAMP-based assays are sufficiently sensitive to detect DNA well below the amount present in ...

Structural and functional properties of integral membrane proteins are often studied in detergent micellar environments (proteomicelles), but how such proteomicelles form and organize is not well understood. This makes it difficult to evaluate the relationship between the properties of the proteins measured in such a detergent-solubilized form and under native conditions. To obtain mechanistic ...

Previously, toxicity of some synthetic detergents (including laundry detergents) to the plant seedlings several species terrestrial higher plants was discovered in research conducted at Moscow University by S.A.Ostroumov. A new example a detergent found this study. The tested, namely liquid (LLD) “Blue Moon”, which manufactured Blue Moon Group Co, Ltd (Guangzhou, China), produced noticeable phy...

phase domains, leaving the lo-phase domains relatively unchanged as DRMs. Both of these approaches showed that TX100 did not substantially change the relative amounts of membrane in the two phases. By contrast, using calorimetry, Heerklotz and colleagues reported that TX100 can induce phase separation in previously uniform mixtures (45, 46). However, results of the other two studies described a...

Musk, A. W., and Gandevia, B. (1976). British Journal of Industrial Medicine, 33, 158-165. Loss of pulmonary elastic recoil in workers formerly exposed to proteolytic enzyme (alcalase) in the detergent industry. Sixty-seven workers in the detergent industry whose exposure to proteolytic enzyme ceased in 1969 have been examined clinically and functionally. By comparison with 42 lightly and moder...

The present paper is a systematic, comparative study on the reconstitution of an apocytochrome b6 purified from a heterologous system using a detergent-free method and reconstitution into liposomes performed using three different detergents: SDS, Triton X-100 and DM, and two methods of detergent removal by dialysis and using Bio-Beads. The product size, its distribution and zeta potential, and ...

The bacterial outer membrane protein OmpA is one of the few membrane proteins whose structure has been solved both by X-ray crystallography and by NMR. Crystals were obtained in the presence of detergent, and the NMR structure is of the protein in a detergent micelle. We have used 10 ns duration molecular dynamics simulations to compare the behaviour of OmpA in a detergent micelle and in a phos...

We have investigated the organization, on the plasma membrane and in detergent-insoluble membrane vesicles, of two neuronal glycosylphosphatidylinositol-anchored (GPI) proteins: Thy-1, a negative regulator of transmembrane signalling; and prion protein, whose rapid endocytosis and Cu(2+) binding suggest that it functions in metal ion uptake. Prion protein occurred on the neuronal surface at hig...
