Method and kit for detecting intrachromosome imbalance in interphase nuclei and their applications

摘要

The invention concerns a method for detecting intrachromosome imbalance in interphase nuclei, characterized in that it consists in: (a) hybridizing in situ the chromosome suspected to be affected by said imbalance using two probes marked with different fluorochromes and specific of said chromosome long arm and short arm respectively; (b) measuring the intensity of the fluorescence emitted in said nuclei with different emission wavelengths corresponding to each of the two fluorochromes; (c) calculating the ratio (Ra) between the two measured values of fluorescence intensity; and (d) comparing the resulting ratio value with at least one reference value. The invention also concerns a kit for implementing said method and uses of said kit and said method, in particular for detecting cancer cells in a biological sample and for diagnosing cancer pathologies.
