Application

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

Other Notes

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

50S ribosomal subunits from the extreme halophilic archaebacterium Haloarcula marismortui were treated with the homobifunctional protein-protein cross-linking reagents diepoxybutane (4 A) and dithiobis(succinimidyl propionate) (12 A). The dominant product with both cross-linking reagents was identified on the protein level as

Neutrophil recruitment (NR) to sites of sterile inflammation plays a key role in tissue damage and healing potential of lesions characteristic to non-infectious inflammatory diseases. Previous studies suggested significant genetic control of neutrophil survival, function, and migration in inflammatory responses
