A PCR reaction consists of the template DNA, two primers covering the amplification site, an enzyme, and buffers. The resulting amplicons are generally detected by gel electrophoresis and for some further applications like cloning, sequencing, amplicon product needs to be recovered from the gel and subsequently purified. However, non-specific product amplification and primer-dimer formation during set-up make gel extraction difficult. Nevertheless, high-quality DNA polymerase and optimize reaction buffers will certainly lead to a successful PCR reaction.

TUNEL assay is the cell death detection method where the biochemical marker of apoptosis is DNA fragmentation. The assay involves the microscopical detection of generated DNA fragments with free 3'-hydroxyl residues. in apoptotic cells using enzyme terminal deoxynucleotidyl transferase (TdT) which adds biotinylated nucleotides at the site of DNA breaks. Major challenges of this method involve proper access of the enzyme which could be hampered by poor permeabilization and/or excessive fixation with cross-linking fixative (common with archival tissue). This issue can be resolved by optimizing the incubation time with Proteinase K or CytoninTM.
