The word agglutination comes from the Latin agglutinare, meaning to glue.. Agglutination occurs if an antigen is mixed with its corresponding antibody called isoagglutinin. This term is commonly used in blood grouping.This occurs in biology in three main examples: 1  The clumping of cells such as bacteria or red blood cells in the presence of an antibody or complement.he word agglutination comes from the Latin agglutinare, meaning to glue.. Agglutination occurs if an antigen is mixed with its corresponding antibody called isoagglutinin. This term is commonly used in blood grouping.
Microfilaments are made up of actin subunits (G-actin monomers) G-actin (globular actin) monomers are globular proteins of 375 amino acids. Each G-actin monomer is described as having both a barbed end, and a pointed end (Figure 2) (Alberts et al.
The myofibrils, as shown in Figure 14-2, are composed of proteinaceous structures called myofilaments. One filament is thick, about 11 nm in diameter and 1.5 m long, whereas the other is thin, 5 nm in diameter and 1 m long. These filaments are referred to as the thick filaments and thin filaments, respectively. Thick filaments are made up of several hundred myosin molecules, proteins of a molecular weight of about 500,000, and some other minor proteins whose function is unknown.
