    When working with this process, it's important to not only know the differences between the stains but the inherent health risks. Molecules of the dye adhere to DNA strands and fluoresce under UV light, showing you exactly where the bands are within the gel.

    The lack of a need for DNA damage signaling in p53 activation by chloroquine would also be concordant with the mechanism of DNA interaction of chloroquine, which intercalates into, but does not damage DNA. 21 A scenario could be envisioned whereby DNA intercalation by chloroquine, while unrecognized as DNA damage by the genome surveillance. Deformation of DNA by an intercalating agent. DNA intercalators are less sequence selective than minor groove binding agents, and, in contrast with them, show a preference for G-C regions. This selectivity is mainly due to complementary hydrophobic or electrostatic interactions, which are due to substituents attached to the Chloroquine does not bind to DNA by the standard intercalation mechanism typical of quinacrine and ethidium. Interestingly, although quinacrine differs only in the intercalating ring core and quinine only in its non-intercalating part, both are reversible intercalators; however, chloroquine is an irreversible intercalator.

    SYBR Gold dye can be used to stain double or single-stranded DNA​ or to stain RNA. Despite its advantage, the downside is that ethidium bromide is a potential carcinogen, so it must be handled with great care.

  7. The DNA Unwinding Kit Theory Unwinding of the double strands of the DNA helix is a hallmark feature of intercalating drugs, such as chloroquine, ethidium bromide and m-AMSA. As part of characterization of novel agents, it is often important to know whether a novel compound is a DNA intercalator.

    The mode of action of chloroquine is still controversial. Proposed mechanisms of action include 1 DNA intercalation, 2 lysosome accumulation and 3 binding to ferriprotoporphyrin IX.

Plaquenil-induced toxicity usually will not occur before five years of taking the drug. “Eye damage due to Plaquenil is not common,” he says. “Rarely will anybody who has good vision and minimal symptoms develop loss of central vision or ability to read if annual screening is done and visual are symptoms reported as soon as they occur so.
