Abstract
The method of in situ hybridization has become a significant technique for specific-site chromosome mapping. We show that the resolution of in situ hybridization can be increased by hybridizing the probe to stretched prometaphase chromosomes with high-resolution banding obtained after 5-bromodeoxyuridine treatment of the cells and with a Hoechst 33258/Giemsa chromosome-staining method. Using this procedure, we assigned to specific chromosome sites three cloned genes and one DNA polymorphism: amylase gene (AMY) to 1p21; proopiomelanocortin gene (POMC) to 2p23, somatostatin gene (SST) to 3q28, and a single copy DNA segment (D3S1) to 3q12.Entities:
