Screening for protein–protein interactions with asymmetrical flow field-flow fractionation [PDF]

Journal of Pharmaceutical Sciences, 2021
We describe a new method for screening protein-protein interaction of biopharmaceutical molecules at dilute concentrations to predict development issues at high concentration. The method is based on Asymmetrical Flow Field-Flow Fractionation (AF4) measurements using well known effects of protein-protein attraction on the fractionation profile due to ...

A new way of valorizing biomaterials: the use of sunflower protein for 1 a-tocopherol microencapsulation [PDF]

, 2013
Biopolymer based microparticles were efficiently prepared from sunflower protein (SP) wall material and a-tocopherol (T) active core using a spray-drying technique. Protein enzymatic hydrolysis and/or N-acylation were carried out to make some structural
