✦ Synopsis

Transferrin (TF) subtyping was carried out on bloodstains that had been made on cotton sheeting and stored under a variety of conditions ranging from -20 degrees C to +37 degrees C. The time limit of detection was longer than 54 weeks after dry storage under each condition. Moreover the correlation between isoprotein types of the TF in blood and semen samples from the same individual was determined in 103 men. All three TF common types and two rare types in all semen samples correlated with the type found in the corresponding blood sample. A combination of isoelectric focusing separation and immuno-enzyme-linked detection may prove to be very useful for forensic TF subtyping.

Simultaneous subtyping of Gc and TfC by isoelectric focusing allows us to compute the following gene frequencies for the Belgian population: Gc1S = 0.543 Gc1F = 0.167 Gc2 = 0.290 TfC1 = 0.784 TfC2 = 0.206 TfB = 0.007 TfD = 0.003. The Gc bands were precipitated by sulfosalicylic acid instead of by im
