Hoechst 33258 CAS:23491-45-4 Kumukūʻai Mea Hana

He dye fluorescent ʻo Hoechst 33258 i hoʻohana pinepine ʻia e hoʻoluʻu i ka DNA. Ua ʻike ʻia no kona hiki ke hoʻopaʻa i nā ʻāpana waiwai AT o ka DNA a hana i ka fluorescence polū ke hoʻonāukiuki ʻia e ka mālamalama ultraviolet. ʻO kēia waiwai e lilo ia i mea pono no ka nānā ʻana a me ke aʻo ʻana i ka DNA i loko o nā cell a me nā ʻiʻo me ka hoʻohana ʻana i ka microscopy fluorescence a me ka cytometry kahe. Eia kekahi, hoʻohana ʻia ʻo Hoechst 33258 i nā ʻano hana e like me ka fluorescence in situ hybridization (FISH) e ʻike i nā moʻo DNA kikoʻī i loko o kahi cell.
