PCR from human placental DNA, in a 50-µL reaction spiked with varying volumes of ethanol, isopropanol (IPA), competitor wash buffers, guanidinium isothiocyanate (GTC) and ChargeSwitch wash buffer. Ten microliters of amplified product run on a 1% agarose gel and stained with ethidium bromide...
Types of Ions: Cations and Anions To create an ion, atoms gain or lose electrons. Two types of ions can be created due to the gain and loss of electrons, they are called cations and anions. Those atoms that lose electrons are called cations due to the overall positive charge on the ...

Surface charge of biological and medical nanocarriers has been demonstrated to play an important role in cellular uptake. Owing to the unique physicochemical properties, charge-reversal delivery strategy has rapidly developed as a promising approach for
The temperature dependence of the hole photoresponse in silver bromide single crystals is measured in the temperature range 200 to 300°K. The bulk lifetime of photoexcited holes is shown to pass through a minimum at temperatures where the drift mobility exhibits a maximum value. The analysis of...
a snapshot of the positive electrode at 50 ps in the MD simulation, with atoms colored by their instantaneous charges (a); the probability distributions of electrode charges varying with time (gray contour) and their average (dashed line) (b); evolution of ion number density with time (...
The first life science imaging CCD camera systems were developed for gel documentation of samples stained ethidium bromide and illuminated with a UV lightbox, or just colorimetric stain and white light illumination. Detecting radioisotopes with a CCD camera is a much bigger challenge, because the ...
Determine the oxidation number of the metallic element(s) in the compound K2Cr2O7. What is the oxidation number of the central metal ion in Na(Ag(CN)2)? What is the common oxidation number for the potassium ion, carbide ion, bromide ion, zinc ion, and barium ion?
of the hydrolytic work-up by the addition of other nucleophilic sources such as chloride (38), bromide (39) or iodide (40) resulted inanti-halogenated products. Interestingly (Fig.3), interception with amides such asN,N-dimethylacetamide or -formamide resulted in the isolation ofanti-acyloxy-...
Thus, particle surface charge is usually characterized using zeta potential (ZP), which is the electrostatic potential of the particles measured at the distance from the surface where ions are not bound to the particle (Moore et al., 2015). ...
