Binding resembles the insertion of a two-pronged “plug” the phosphotyrosine and isoleucine side chains

of the peptide into a two-pronged “socket” in the SH2 domain.

Overall, there are three pillars electrophoresis

Current / voltage

Medium - (buffer/liquid) - with a precise pH value and a constant ionic strength.

 Analytes - A compound, which is to be detected or assayed in a given sample.

Electrophoretic resolution mainly can be change by manipulating current and buffer system.

The higher the buffer concentration, the more electric power is applied, resulting in higher heat (joule effect) development.

Smiling Effect, Venetian Blind Effect & Electroendosmosis reduces the efficiency of electrophoresis.
