A new trend gaining popularity among people trying to lose weight is microdosing the diabetes medication Ozempic. With approximately 70% of American adults meeting the criteria for being obese or ...
SYBR Gold is an intercalator.This means it binds to DNA by insertion of one dye molecule between two planar bases / base pairs of DNA. Single molecule magnetic tweezers assays reveal systematic lengthening and unwinding of DNA by 19.1º ± 0.7º per dye molecule upon binding, consistent with intercalation.
