일반 설명

Buffered picric acid-paraformaldehyde fixative is suitable for use in electron microscopy and light-microscopic immunocytochemistry.

애플리케이션

Paraformaldehyde was used in the preparation of azomethine ylide, required for the synthesis of amine-modifying single-walled carbon nanotubes. It was also used in the preparation of α-methylenechromanes, α-methylenequinoline and ortho-quinone methides.

We aimed to create a more robust and more accessible standard for amine-modifying single-walled carbon nanotubes (SWCNTs). A 1,3-cycloaddition was developed using an azomethine ylide, generated by reacting paraformaldehyde and a side-chain-Boc (tert-Butyloxycarbonyl)-protected, lysine-derived alpha-amino acid, H-Lys(Boc)-OH, with purified SWCNT

The buffered picric acid paraformaldehyde fixative originally recommended for electronmicroscopy and which has since been used occasionally for light-microscopic immunocytochemistry, has been supplemented with glutaraldehyde and used as primary fixative for the perfusion of rat brains. In the basal ganglia

Optical clearing methods can facilitate deep optical imaging in biological tissue by reducing light scattering and this has enabled accurate three-dimensional signal visualization and quantification of complex biological structures. Unfortunately, existing optical clearing approaches present a compromise between maximizing clearing
