Note: Although it is possible to perform in situ hybridization on bleached embryos, it appears to reduced the strength of the signal. For best results, use albino females.in situ hybridization - Harland , R.M. 1991. Meth. Cell Biol. 36:685. The first time you use a particular probe it is worthwhile to preabsorb it. This takes about 24 h and dramatically increases the quality of the final product.&......閱讀全文

2)標本變性①將制備好的染色體玻片標本于 50oC培養箱中烤片2~3h。(經Giemsa染色的標本需預先在固定液中退色后再烤片)。②取出玻片標本,將其浸在70~75oC的體積分數70%甲酰胺/2×SSC的變性液中變性2~3min。③立即按順序將標本經體積分數70%、體積分數90%和體積分數100%冰
雙重和多重原位雜交(hybridization-in-situ)技術
為了在同一標本上或同一細胞內同時檢測是否存在兩種或兩種以上的靶核酸序列。可應用雙重或多重原位雜交技術.即以兩種或多種標記探針與靶核酸雜交。然后利用不同的檢測手段分別顯示各種靶核酸的存在和分布。該技術與免疫組織化學技術中的雙重或多重標記相似,除了探針本身的特異性外,對結果的干擾主要來自標記物及檢測試劑
