ABO and Lewis typing of secretion stains on nitrocellulose membranes using a new dot-blot-ELISA technique.

Author information

Landeskriminalamt Baden-Württemberg Kriminaltechnisches Institut, Stuttgart.


A new method for ABO and Lewis typing of body fluids is described. It combines the advantages of a good antigen binding to nitrocellulose membranes, the need of only very small amounts of stain material and the high sensitivity of an enzyme-linked immunosorbent assay for antigen detection. This is of special interest because conventional ABO and Lewis typing of secretion stains need relatively large stain dimensions. The method is very easy to handle, does not need any expensive equipment and gives a permanent record. Furthermore the high sensitivity offers the possibility of analyzing even sweat and urine stains without the need of concentrating these extracts.
