    Chloroquin extends contour length of dna

    The contour length of a polymer chain (a big molecule consisting of many similar smaller molecules) is its length at maximum physically possible extension.

    The contour length of all three constructs was shorter than theoretically predicted assuming 3.4 Å/bp for B-DNA in accordance with previous findings. In addition, according to our analysis, the contour length of the methylated DNA constructs was 3% shorter than that of the nonmethylated form Fig. S6; Table 1. Model 8–10, from which a persistence length, P, and a contourlength,L o,canbeobtained. Between10and65pN,the molecule deviates from the predictions of the inextensible WLC as it extends beyond its B-form contour length. From this ‘‘enthalpic elasticity’’ regime an elastic stretch modulus, S, can be obtained. The dissociation constant of the DNA-chloroquine complex varied from 27 microM to 2.6 mM, depending on the ionic strength of the buffer. Our results suggest that chloroquine binding to DNA is highly dependent on salt concentration.

    A surface 2. To measure the contour length of a single molecule by using optical techniques directly, it is necessary to extend the polymer such that a one-to-one mapping can be established between the spatial position along the polymer and position within the genome. Confinement elongation of genomic-length DNA has several In order to stretch DNA further, we used chloroquine, which intercalates into and extends the contour length of double-stranded DNA. When this mixture was drawn at a rate of 100 μl/min, λ DNA molecules were stretched to 85–95% of the contour length of B-form DNA Fig. 2 C-iv and 3 D. Chloroquine is a 4-aminoquinoline with antimalarial, anti-inflammatory, and potential chemosensitization and radiosensitization activities. Although the mechanism is not well understood, chloroquine is shown to inhibit the parasitic enzyme heme polymerase that converts the toxic heme into non-toxic hemazoin, thereby resulting in the accumulation of toxic heme within the parasite.

    RA and Hydroxychloroquine How Effective is it for Rheumatoid. Generally, hydroxychloroquine is given in 200 mg or 400 mg doses, once per day. Higher doses can sometimes be used, but only in adults and not for all cases. Some people tolerate this medication much better than other people, so it is important that individuals who are considering taking hydroxychloroquine talk with their doctor about the.
