Locus symbol: Ddbl, Gif, cfll. Map position: Mouse Chromosome 19 Methods of mapping: Fluorescent in situ hybridization (FISH) on mouse SV22-CD cell line metaphase chromosomes [1]. Mouse x hamster somatic cell hybrids analysis. Molecular reagents: The human 4.2-kb DDB 1 cDNA [21 was labeled with biotinylated-14-dUTP and nick-translation kit GIBCO BRL (No. 8247 SA), hybridized (200 ng per slide) in the presence of 10 p.g of mouse Cotl DNA (Life Technologies- Fig. 1. Fluorescent in situ hybridization of the human DDB1 probe on GIBCO BRL, Cergy Pomtoise, France), and revealed by avidin- mouse SV22CD cell line metaphase chromosomes [1]. The probe was labeled with biotinylated-14-dUTP and a nick-translation kit GIBCO BRL FITC (Vector Laboratories) as previously described [3]. Meta- (n° 8247 SA) and hybridized as previously described [3]. Metaphase phase spreads were analyzed under an Axiophot (Zeiss) micro- spreads were analyzed under an Axiophot (Zeiss) microscope.
