WebWe present a polymerase chain reaction-restriction fragment length polymorphism method to simultaneously distinguish the two Anopheles gambiae M and S molecular forms and Anopheles arabiensis. This method uses different diagnostic sites than previously published methods, and it is based on the amplification of a smaller ribosomal DNA fragment. WebNov 8, 2024 · RNA-seq requires the enrichment of mature mRNAs, or the depletion of highly abundant ribosomal RNAs (rRNAs) from total RNA before sequencing. RNAs from FFPE materials are usually degraded to small sizes without the 3′poly (A) tail; moreover, recent studies suggest that certain functionally important mRNAs are non-poly (A) RNAs . …
