背景介紹：Apoptosis is a cell death process that removes toxic and/or useless cells during mammalian development. The apoptotic process is accompanied by shrinkage and fragmentation of the cells and nuclei and degradation of the chromosomal DNA into nucleosomal units. DNA fragmentation factor (DFF) is a heterodimeric protein of 40-kD (DFFB) and 45-kD (DFFA) subunits. DFFA is the substrate for caspase-3 and triggers DNA fragmentation during apoptosis. DFF becomes activated when DFFA is cleaved by caspase-3. The cleaved fragments of DFFA dissociate from DFFB, the active component of DFF. DFFB has been found to trigger both DNA fragmentation and chromatin condensation during apoptosis. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene but the biological validity of these variants has not been determined.

DNA斷裂因子抗體,Anti-DFFB抗體免疫組化問題解答

1、染色過強(qiáng)？

原 因：抗體濃度過高或孵育時(shí)間過長

解決方法：降低抗體滴度、抗體孵育時(shí)間：室溫1小時(shí)或4度過夜

原 因：孵育溫度過高超過37度

解決方法：一般在室溫20-28度

原 因：DAB顯色時(shí)間過長或濃度過高

解決方法：顯色時(shí)間不超過5-12分鐘，以顯微鏡下觀察為準(zhǔn)

2、非特異性背景染色？

原 因：操作過程中沖洗不充分

解決方法：每步?jīng)_洗3次每次5分鐘

原 因：組織中含過氧化物酶未阻斷

解決方法：可再配置新鮮3%H2O2封閉孵育時(shí)間延長

原 因：組織中含內(nèi)原性*

解決方法：正常非免疫動(dòng)物血清再封閉

原 因：血清蛋白封閉不充分

解決方法：血清蛋白封閉不充分
