倪老师,我在wiki上查到的是7-Aminoactinomycin D (7-AAD) is a fluorescent chemical compound with a strong affinity for DNA. It is used as a fluorescent marker for DNA in fluorescence microscopy and flow cytometry. It intercalates in double-stranded DNA, with a high affinity for GC-rich regions,making it useful for chromosome banding studies。7aad是不是之作用于DNA啊? |
