Description

Application

Useful reagent for the oxidation of carbohydrates prior to labeling with biotin hydrazide

Sodium periodate is use in molecular biology and carbohydrate research to cleave carbon-carbon bonds of carbohydrates alginates, chitosans, hyaluronan, scleroglucan/schizophyllan, cellulose nucleic acids other molecules rich in hydroxyls and ketones to prepare them for chemical and physical modifications.

Other Notes

Periodate oxidation of agarose gels in enzyme immobilization; Preparation of oligonucleotide 3′-dialcohols in ribonucleoside labeling; Cleavage of cross-linked proteins.
