摘要: Publisher Summary Antibody polypeptide chains are composed of domains with each domain consisting roughly 110 amino acids. There is a single variable region in both light and heavy chains. The constant the chain also (C, or C,), whereas has three four domains. depending upon class. Each domain, as well short hinge region, corresponds to separate exon DNA. Constant genes i n mouse human located on different chromosomes; C-region one cluster, whilst C, chromosomes. A major difference exists between expression genes. five antibody classes known man (IgM, IgD, IgG, IgE, IgA); class determined by expressed ( μ, δ, γ , ɛ α ) without regard chain. multiple for . In addition pseudogenes have been found immunoglobulin cluster.
