General description

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。

Application

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。

Synthesis, pharmacokinetics, and biological use of lysine-modified single-walled carbon nanotubes.

J Justin Mulvey et al.

International journal of nanomedicine, 9, 4245-4255 (2014-09-18)

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

A note on the use of picric acid-paraformaldehyde-glutaraldehyde fixative for correlated light and electron microscopic immunocytochemistry.

P Somogyi et al.

Neuroscience, 7(7), 1779-1783 (1982-07-01)

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

Synthesis of new chlorin e6 trimethyl and protoporphyrin IX dimethyl ester derivatives and their photophysical and electrochemical characterizations.

José C J M D S Menezes et al.

Chemistry (Weinheim an der Bergstrasse, Germany), 20(42), 13644-13655 (2014-08-30)

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

Decorin-mediated inhibition of the migration of U87MG glioma cells involves activation of autophagy and suppression of TGF-β signaling.

Ting Yao et al.

FEBS open bio, 6(7), 707-719 (2016-07-12)

Decorin (DCN) is a major member of the small leucine-rich proteoglycan (SLRP) family that is critically involved in tumorigenesis and the development of metastasis of cancers, including glioma. Overexpression of DCN was indicated to suppress glioma cell growth. However, the

Hormesis enables cells to handle accumulating toxic metabolites during increased energy flux.

Johanna Zemva et al.

Redox biology, 13, 674-686 (2017-08-22)

Energy production is inevitably linked to the generation of toxic metabolites, such as reactive oxygen and carbonyl species, known as major contributors to ageing and degenerative diseases. It remains unclear how cells can adapt to elevated energy flux accompanied by
