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.
Microfilaments. The microfilament system is a network of filaments 6 nanometers (nm) in diameter that are important for anchoring plasma membrane proteins, for producing cell movement, and for cell division. The base filament is composed of a protein called actin that is 42 kilodaltons (kd) in weight.nlike the other systems, which are composed of one or two different proteins, intermediate filaments can be formed by a relatively large number of different proteins. For example, the primary intermediate filaments found in epithelial cells (such as skin) are formed from pairs of keratins, one basic and one acidic.
