isoelectric

[ī′sō·ilek′trik]
Etymology: Gk, isos + electron, amber
pertaining to the electric baseline of an electrocardiogram, which is the period between the end of the T wave and the beginning of the P wave.

isoelectric

showing no variation in electric potential.

isoelectric focusing
an electrophoretic method for separating proteins in gels which depends on the fact that the net charge on the protein varies with the pH of the surrounding medium. At the isoelectric point the protein has no net charge and will not therefore migrate further in an electric field. The polyacrylamide gel is cast in a narrow tube that provides a pH gradient from top to bottom.
isoelectric period
the moment in muscular contraction when no deflection of the galvanometer is produced.

On the other hand, the proposed algorithm did not require the determination of isoelectric level.
With more proteins quantitative loading more proteins quantitative loading the gel showed obvious streaking and high background and the highly abundant proteins were too large to cover other important proteins with similar molecular weight and isoelectric point and with lower proteins quantitative loading it was not suitable for detect the low abundant proteins which might play an important role in the life.
