Immunoglobulin Amino Acid Sequence
Immunoglobulin Amino Acid Sequence . These proteins differ in amino acid sequence in from 38 to 48 positions; These cdnas contain sequence information for a portion of the variable region and all of the constant region. Introduction to Antibody Structure from people.cryst.bbk.ac.uk Igg and iga are further grouped into subclasses (e.g., in human igg1, igg2, igg3, igg4, iga1, and iga2) based on additional small differences in the amino acid heavy chain sequences. There are 5 types of heavy chains designated α (alpha), δ (delta), ɛ (epsilon) γ (gamma) and µ (mu) in. Entire immunoglobulin is a tetramer consisting of two identical high molecular weight or heavy chains and two low molecular weight or light chains.
