Protein isolation Tissue

The formation of DNA from an RNA template using reverse transcription leads to the formation of double-stranded complementary DNA or cDNA. The challenges with this process include 1. Maintaining the integrity of RNA, 2. Hairpin loops or other secondary structures formed by single-stranded RNA can also affect cDNA synthesis, and 3. DNA-RNA hybrids, which may result when the first strand of cDNA is formed. For the first challenge, using workflows that involve proper isolation and storage of RNA, and maintaining a nuclease-free environment helps obtain RNA with ideal 260/230 ratios. Using a reverse transcriptase that can tolerate high temperatures (50-55oC), overcomes obstacles imposed by secondary RNA structures. Finally, RNase H has the ability to hydrolyze RNA before the formation of a second cDNA strand. It is important to ensure that RNase H activity is optimal because higher RNase H activity leads to premature degradation of the RNA template. Many reverse transcriptases offer built-in RNase H activity.

As autophagy is a multi-step process which includes not just the formation of autophagosomes, but most importantly, flux through the entire system, including the degradation upon fusion with lysosomes, which makes it quite challenging for detection. There are several methods for detection in mammalian cells, including immunoblotting analysis of LC3 and p62 and detection of autophagosome formation/maturation by fluorescence microscopy, Currently, there is no single “gold standard” for determining the autophagic activity that is applicable in every experimental context, hence it is recommended to go for the combined use of multiple methods to accurately assess the autophagic activity in any given biological setting.
