[Evaluation of unusual band patterns in immunochemophoresis]
The occurrence of unusual band patterns in the protein systems Gc, F XIII B and PLG is described. During the routine investigation of these systems in paternity, identity and criminal cases, several examples of alterations or additions to the normal band patterns have been observed. This was particularly noticeable in post mortem samples, stored liquid blood samples and blood stains. A connection between alterations in the form due to charge changes and changes to the isoelectric point from ageing of blood samples is demonstrated.
