The Distribution of ABH-Bloodgroup Substance in Seminal Stains
To guarantee an economical utilization in bloodgrouping of seminal stains the various bloodgroup systems should be investigated in the region of their maximum concentration. The distribution for the Gm and PGM1 system is already known. In the present study the distribution of the ABH-substance was investigated using artificially made seminal stains and an inhibition test (“master titration”). The results demonstrate that in samples of equal size the absorption and therefore the concentration of bloodgroup substances is higher in peripheral sections, or at least not lower than in other regions of the seminal stain.
