full_question: The brand name Vysis is used by a series of devices employed in this technique, which come in "dual-fusion" and "break-apart" variants. A common application of this technique is to detect the fusion of BCR and ABL. The techniques SKY and CGH are alternatives to a "multiplex" version of this technique which typically uses 24 different colors. It's not PCR, but telomere length can be determined using either a quantitative version of this technique or a version which combines this technique with flow cytometry. A stain such as DAPI can be used to label metaphase chromosomes attached to a glass slide in this technique. For 10 points, name this technique in which chromogenic or fluorescent probes are used to detect individual genetic sequences within chromosomes.

raw_answer: in situ hybridization [or ISH; or fluorescent in situ hybridization; or chromogenic in situ hybridization; or FISH; or CISH; prompt on "flow cytometry" until it is read]
