IPA: //əˈɡluːtɪnɪn//
KK: /əˈɡluːtɪnɪn/
A type of substance that can cause clumping of cells or particles, particularly in the context of blood or bacteria.
The agglutinin in the serum reacted with the bacteria, causing them to clump together.
Agglutinin is formed from "agglutinare" (meaning to glue together) and the suffix "-in" (used to denote proteins or substances). The word describes a substance that causes particles to stick together, particularly in the context of biological processes.
Think of 'gluing together' ('agglutinare') to remember that an agglutinin is a substance that causes things to stick together.
