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.
1 Microfilaments are responsible or essential for cell shape, membrane protrusions such as microvilli, lamellipodia etc, adhesion to other cells and matrix, intracellular vesicular traffic, and cell motility. 2  In muscle microfilaments constitute a major structure of the contractile unit, the other being myosin II. Actin is hydrolyzed to its ADP form in the microfilament, a reaction that permits the filament to disassemble at a later time. 2  Growing microfilaments may also form branches if nucleation on one side occurs by the attachment of branching complex ARP 2/3 (actin-related-protein 2/3).
