Application

N-Hydroxysulfosuccinimide sodium salt is a water-soluble sulfonated analog of N-hydroxysuccinimide. It can undergo a coupling reaction with carboxylic acids in the presence of carbodiimides such as 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide(EDC) to form hydrophilic N-hydroxysulfosuccinimide active esters. These esters are useful in protein cross-linking experiments.

Packaging

Bottomless glass bottle. Contents are inside inserted fused cone.

Other Notes

Sulfo-NHS is used for preparing hydrophilic active esters, e.g. for crosslinking agents

The construction of antibacterial and antitumor coatings could offer effective routes to improve the therapeutic effects of non-vascular stents for unresectable obstructions caused by malignant tumours. Herein, polyelectrolyte multilayers have been explored as bactericidal coatings with controlled antitumor drug release.

Nanomaterial-based field-effect transistor (FET) sensors are capable of label-free real-time chemical and biological detection with high sensitivity and spatial resolution, although direct measurements in high-ionic-strength physiological solutions remain challenging due to the Debye screening effect. Recently, we demonstrated a general
