Development of spectral colour banding in cytogenetic analysis

We developed a novel chromosome banding technique-spectral colour banding ( SCAN), With this technique we displayed a multicolour banding pattern that almost entirely correlated with the corresponding G-banding pattern. With S CAN analysis we could identify the chromosome-band origin of double minute chromosomes in gastric cancer. Our preliminary use of this technique sugges ts that it has significant clinical applications for cytogenetic analysis.
