Cholera Toxin Subunit B for Sensitive and Rapid Determination of Exosomes by Gel Filtration

open access: yesMembranes, 2020
We developed a sensitive fluorescence-based assay for determination of exosome concentration. In our assay, Cholera toxin subunit B (CTB) conjugated to a fluorescence probe and a gel filtration technique (size-exclusion chromatography) are used. Exosomal

MOLECULAR-MASS DISTRIBUTION OF HUMIC ACIDS OF PERMAFROST PEAT MOUNDS FROM THE EUROPEAN NORTHEAST OF RUSSIA

open access: yesИзвестия Томского политехнического университета: Инжиниринг георесурсов, 2019
The relevance of the research is caused by the polydispersity of humic acids and their insufficient study in peat soils of cryolithozone. The main aim of the research is to study the molecular mass distribution of humic acids in soils of mounds peatlands.
