BASys (Bacterial Annotation System) is a tool for automated annotation of bacterial genomic (chromosomal and plasmid) sequences including gene/protein names, GO functions, COG functions, possible paralogues and orthologues, molecular weights, isoelectric points, operon structures, subcellular localization, signal peptides, transmembrane regions ...
In practice, a protein with an excess of basic aminoacids (arginine, lysine and/or histidine) will bear an isoelectric point roughly greater than 7 (basic), while a protein with an excess of acidic aminoacids (aspartic acid and/or glutamic acid) will often have an isoelectric point lower than 7 (acidic).
The three samples are mixed and loaded onto IEF (isoelectric focusing chromatography) for first dimension and the strip is transferred to a SDS PAGE.After the gel electrophoresis, the gel is scanned with the excitation wavelength of each dye one after the other, so each sample can be seen separately (if we scan the gel at the excitation wavelength of the Cy3 dye, we will see in the gel only ...
The two dimensions that proteins are separated into using this technique can be isoelectric point, protein complex mass in the native state, or protein mass. [citation needed] The separation by isoelectric point is called isoelectric focusing. Thereby, a pH gradient is applied to a gel and an electric potential is applied across the gel, making ...
The LOC100287387 protein is formed by a 423 amino acid peptide sequence. The molecular mass is 44.4 kdal, [5] and the isoelectric point is 10.77. [6] There is a G-patch domain and a short domain of unknown function within the peptide sequence.
2D immunoelectrophoresis is a potential method that can be used for a range of functions involving protein flow of migrants, such as the deep examination of protein opsonization, in succession of first dimension as an activity of protein molar mass and the second dimension as a role of the isoelectric point.
Isoelectric focusing (IEF), also known as electrofocusing, is a technique for separating different molecules by differences in their isoelectric point (pI). [ 1 ] [ 2 ] It is a type of zone electrophoresis usually performed on proteins in a gel that takes advantage of the fact that overall charge on the molecule of interest is a function of the ...
At the isoelectric point the relationship between the dielectric constant and protein solubility is given by: log S = k / e 2 + log S 0 {\displaystyle \log S=k/e^{2}+\log S^{0}\,} S 0 is an extrapolated value of S , e is the dielectric constant of the mixture and k is a constant that relates to the dielectric constant of water.
