一般描述

缓冲苦味酸-多聚甲醛固定剂适用于电子显微镜和光显微镜免疫细胞化学。

应用

多聚甲醛可以用来制备亚甲胺叶立德。在氨基修饰单壁碳纳米管合成中也需要要用到多聚甲醛。它还可以用来制备 α-亚甲基色原烷, α-亚甲基喹啉和正色-醌甲基化物。

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

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

In view of increasing demands for efficient photosensitizers for photodynamic therapy (PDT), we herein report the synthesis and photophysical characterizations of new chlorin e6 trimethyl ester and protoporphyrin IX dimethyl ester dyads as free bases and Zn(II) complexes. The synthesis of these

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
