Summary

자동 번역

Fluorescerende in situ-hybridisering (FISH) muliggør påvisning af nukleinsyrer i deres native miljø i cellerne. Vi her beskrive en protokol for den kombinerede, samtidig påvisning af RNA og DNA ved hjælp af fisk, som kan bruges til at studere X-kromosom inaktivering i muse embryonale stamceller.
