The process that occurs after agglutination
Did you know?
WebbAgglutination is the process that 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 two main examples: The clumping of cells such as bacteria or red blood cells in the presence of an antibody or complement. Webb11 apr. 2024 · DNA methylation often occurs on CpG islands, a region of more than 200 bases formed by aggregation of CpG dinucleotides , and the methylation process is mainly mediated by DNMT family enzymes. The enzyme catalyzes the transfer of methyl groups from S-adenosylmethionine to DNA, and it is currently thought that only DNMT1 (DNA …

In this assay, antigen in the sample competes with the antigen coated on the RBCs for their interaction with antibody. Another variation of the HIA is reverse passive hemagglutination assay, in which the purified antibody is coupled to the RBCs.
