WebThe sesame protein isolate displayed almost identical zeta potential profiles with its pH. The decreasing pH increased the zeta values gradually from the lowest negative value to the highest positive value. The zeta potentials of standard and defatted sesame seeds at pH 7 were -23.53 and -17.30, respectively. WebFeb 14, 2024 · The isoelectric point (pI) is the point at which the net charge on a molecule is zero. pI is most commonly examined for proteins. Each of the amino acids in a protein …
WebThus, the pI of a protein indicates its net charge, a critical determinant of its stability/activity in a given milieu. Conventionally, the first-dimensional IPG-IEF is followed by a second dimension, by which the focused proteins are denatured/reduced and resolved on an SDS-PAGE gel for subsequent immunoblotting to verify the protein identity. WebProtParam (References / Documentation) is a tool which allows the computation of various physical and chemical parameters for a given protein stored in Swiss-Prot or TrEMBL or …
