Innate Immune System
01/28/25 • 47 min
The immune system is split up into two main categories - the adaptive immune system and the innate immune system.
This episode will cover the intricacies of the innate immune system beginning with an overview of its constituent cells. We will then explore three pivotal elements of the system: anatomical barriers, the general inflammatory response, and the complement system. This will show up in the bio/biochem section of the MCAT.
For additional reading on this topic, you can refer to the NIH’s Innate Immune System paper.

Separation and Purification Techniques
This episode of MCAT Basics covers several separation and purification techniques you may see on the MCAT. We’ll cover these techniques in three distinct categories: small molecules, proteins, and cells.
Within the small molecule category, we’ll discuss extraction, crystallization and recrystallization, and chromatography (TLC and HPLC).
For proteins, we cover SDS-page, precipitation, soelectric focusing, and chromatography variations. Lastly, we’ll explain, within the world of cells, centrifugation, flow cytometry, and microfluidics.

Adaptive Immune System
To continue our discussion on the immune system, in this episode, we will cover the second type of immune system – the adaptive immune system.
We start with covering some vocabulary that you’ll need to know to understand the immune system, then we move into the cells that make up the adaptive immune system. Then we break down the two branches of the adaptive immune system - humoral immunity including the discussion of B cells and cell-mediated immunity highlighting T cells.
Don’t miss our previous episode on the other type of immune system, the innate immune system.
