Ask A Scientist: Proteoglycans vs. Glycoproteins

The extracellular matrix is a complex combination of non-cellular materials that support biochemical and biomechanical processes in the tissues and organs. Among the components of the extracellular mix are two distinct types of biomolecules: proteoglycans and glycoproteins. Immunology researchers are primarily interested in these biomolecules due to their role in the human tissue processes and…

Ask A Scientist: What’s the Difference Between Primary and Immortalized Cells?

While most researchers today prefer primary cells for immunology, inflammation, and vaccination experiments due to the close match to in vivo function, immortalized cell lines still have advantages and preferred use cases. Let’s take a closer look at the differences between the two cell types. Understanding the Difference Primary cells are isolated directly from a…
