Comparative chromosome band mapping in primates byin situ suppression hybridization of band specific DNA microlibraries [PDF]
, 1991 A DNA-library established from microdissected bands 8q23 to 8q24.1 of normal human chromosomes 8 (Lüdecke et al., 1989) was used as a probe for chromosomal in situ suppression (CISS-) hybridization to metaphase chromosomes of man and primates including ...
