A team of zoologists discover that direct cell-cell communication plays a key role in the early cardiac development of monitor lizards, and that the molecules responsible for this communication are downregulated in adolescents and adults using a proprietary assay they developed in their lab. Which of the following universally known assays would most directly confirm this difference between embryonic monitor lizards and more fully grown monitor lizards?
  • a)
    Immunohistochemistry, to detect cell-surface proteins and glycoproteins
  • b)
    Southernblot, to detect specific DNA sequences in a sample
  • c)
    Northernblot, to detect specific RNA sequences in a sample
  • d)
    Enzyme-linked Immunospot (ELISPOT), to detect secretory products of cells
Correct answer is option 'A'. Can you explain this answer?

Immunohistochemistry is a commonly used technique that utilizes antibodies to detect and visualize specific proteins or glycoproteins within tissue samples. In this case, the researchers can use immunohistochemistry to examine the expression levels and localization of the molecules responsible for cell-cell communication in both embryonic and adult monitor lizards. By comparing the staining patterns and intensities between the two stages, they can directly confirm any downregulation or difference in the expression of these molecules in adolescents and adults compared to the embryonic stage.
