(A) Schematic of cyclic-array sequencing-by-synthesis methods (for example, fluorescent in situ sequencing, pyrosequencing, or single-molecule methods). Left: repeated cycles of polymerase extension ...

(a) The basic elements of FISH are a DNA probe and a target sequence. (b) Before hybridization, the DNA probe is labeled by various means, such as nick translation, random primed labeling, and PCR.

We describe a technique for transferring electrophoretically separated bands of double-stranded DNA from agarose gels to diazobenzyloxymethyl-paper. Controlled cleavage of the DNA in situ by ...

Excitons, bound states between an electron (i.e., a negatively charged particle) and a hole (i.e., the absence of an electron) in materials, are a key focus of condensed matter physics studies. These ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 90, No. 6 (Mar. 15, 1993), pp. 2509-2511 (3 pages) Scanning force microscopy was used to analyze banded human ...

Peking University, March 19, 2025: A research team led by Professor Sun Qing-Feng in colloboration with Professor He Lin’s research group from Beijing Normal University has achieved orbital ...

Researchers demonstrate orbital hybridization in graphene-based quantum dots, revealing how anisotropic confinement influences electronic states at the atomic scale. Quantum dots, often described as ...
