- Technical Tips for Antigen RetrievalThe basic mechanism of fixation with formaldehyde is the formation of addition products between the formalin and uncharged reactive amino groups (-NH or NH2), forming cross-links. The cross-linking of critical side chains of amino acids is thought to result in selective masking of different epitopes of different antigens, with subtle alterations in the overall 3-dimensional shape of the protein molecule. In addition to inducing cross-linking, formaldehyde also disrupts hydrogen bonds and other electrostatic interactions that affect the configuration of proteins, further increasing the possibility of important alterations to epitopic targets.
- The fully vaccinated should not worry about the Delta variantThe Delta variant, which was first identified in India, is worrisome because it is highly contagious and spreading rapidly around the globe. Unvaccinated people who are infected with Delta are twice as likely to be hospitalized as those infected with Alpha, the variant that was first detected in Britain.
- Insight into viruses (4): The Reverse Transcribing VirusesThe last two groups of viruses of the Baltimore classification system are reverse transcribing (RT) viruses (Groups VI and VII). These viruses are unique in that they use a reverse transcriptase in their life cycle. Reverse transcriptases are RNA-dependent DNA polymerases (RdDP), meaning they make DNA copies from RNA templates. In comparison with other polymerases (DdDPs, DdRPs, and RdRPs) discussed in the previous blog, RdDPs are low fidelity enzymes because they have no 3’ to 5’ exonuclease activity, and they need specific primers to initiate DNA synthesis. All RT viruses code their RdDPs in the genomes and package the enzymes in the virions.
