We have taken two approaches to go define the mechanism by which … WitrynaIgM is the first immunoglobulin that appears on B cells and the first to be secreted during the primary humoral response. It contributes to about 10% of the total Ig content. IgM acts as the initial B cell antigen receptor in a monomeric, membrane-bound form and subsequently can be secreted in a pentameric form by activated B cells.
