Background Accurate estimation of the isoelectric point (pI) based on the amino acid
sequence is useful for many analytical biochemistry and proteomics techniques such as 2-D …

The isoelectric point is the pH at which a particular molecule is electrically neutral due to the
equilibrium of positive and negative charges. In proteins and peptides, this depends on the …

Proteome-pI is an online database containing information about predicted isoelectric points
for 5029 proteomes calculated using 18 methods. The isoelectric point, the pH at which a …

The durability of enzymes in harsh conditions can be enhanced by encapsulation within
metal–organic frameworks (MOFs) via a process called biomimetic mineralisation. Herein …

The net charge and isoelectric pH (pI) of a protein depend on the content of ionizable groups
and their pK values. Ribonuclease Sa (RNase Sa) is an acidic protein with a pI= 3.5 that …

Self-assembled monolayers of ω-mercaptohexadecanoic acid and ω-
mercaptohexadecylamine on gold electrodes are stable at neutral pH and display pure …

This critical review analyzes the behavior of natural and synthetic polyampholytes and
current theoretical descriptions based on Coulomb interactions between complementary …

Casein and soy soluble polysaccharide formed compacted complex aggregates in pH 3–4.5
aqueous solutions by electrostatic and hydrophobic interactions. The diameters of the …

Abstract Proteome-pI 2.0 is an update of an online database containing predicted isoelectric
points and p K a dissociation constants of proteins and peptides. The isoelectric point—the …

Proteins from breast cancer cell lines are characterized using a 2-D liquid separation
technique in which protein p I is used as the first-dimension separation parameter. To effect …
