Web(E) Representative example of sample purity after chloroplast isolation protocol. Many chloroplasts are fully intact, with stromal GFP (green); some were damaged during extraction and have lost stromal GFP, but retain the thylakoid membranes (chlorophyll autofluorescence, red); and very small quantitites of nonfluorescent materials remain with ... WebJan 1, 2011 · The cpDNA can be prepared by isolating chloroplasts using the protocol described in Subheading 3.1.1, followed by the CTAB protocol described in Subheading 3.3.1 starting from step 2 ... Because these methods do not require prior chloroplast isolation, they can be performed quickly and easily. However, this also limits the type of …
