DNA typing of the D1S80 locus was carried out using capillary polyacry
lamide gel zone electrophoresis (CZE). The D1S80 allelic ladder was is
olated within 40 min in polyacrylamide gel columns of 50 mu m inner di
ameter and 30 cm length. The PCR products and ladder marker in the inj
ection port were electrophoresed and detected by UV absorption (254 nm
). The typing was determined according to migration of DNA fragments o
n the electropherograms, which permits simultaneous analysis of both t
he test sample polymerase chain reaction products and the ladder marke
r. The two-step sample injection method applied in this study allows u
s to use minute amounts of the ladder maker. This procedure provides a
reliable, economical and rapid method for D1S80 typing. (C) 1997 Else
