The many pathways of RNA degradation - PubMed
WebHowever, in all but the most degraded sample (panel E) the 18S rRNA peak remains fairly constant among samples, suggesting that this is not associated with large-scale degradation of the RNA sample. Rather, this profile seems to result from breakdown of the 28S rRNA relative to other RNAs. WebThe 18S and 28S ribosomal RNA bands are clearly visible in the intact RNA sample. The degraded RNA appears as a lower molecular weight smear. Generally, at least 200 ng of RNA must be loaded onto a denaturing agarose gel in order to be visualized with ethidium bromide. Some RNA preparations, such as those from needle biopsies or from laser ... 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. shop potatoes
