The shifted proteins are not degraded significantly. Their altered electrophoretic mobility may be due to a change of electrical charge by loss of one or a few end standing amino acids.

The dependence of the quantity of the penetrated virus on the quantity of the attached virus was linear, while there was an accelerating increase of the quantity of the eluted virus depending on the quantity of the attached virus.
