Several parallel observations and several differences in IgG subclass expression were noted between cell lines and normal lymphocytes. Surface IgG2 was frequently expressed in normal IgG\u2010positive lymphocytes but was seldom expressed in cell lines. Cell lines resembled normal IgG\u2010positive lymphocytes in the frequent expression of cytoplasmic IgG3 and lgG4, often without secretion. Cell lines and normal lymphocytes both showed more frequent distribution of IgG and IgG sub\u2010classes in cytoplasm than in surface immunoglobulin, and often a discrepancy of surface versus cytoplasmic IgG subclass. A good correlation was noted between surface, cytoplasmic and secreted IgG1. Despite a predominance of IgG2 and IgG4 surface IgG subclasses, and IgG3 and IgG1 in cytoplasm, secreted immunoglobulins from normal lymphocytes in short\u2010term culture showed a similar distribution of IgG subclasses to that seen in normal sera. Multiple expression of IgG subclasses was much more frequent in IgG\u2010positive cell lines than in normal peripheral blood lymphocytes, both in surface and cytoplasmic IgG.<\/jats:p>","DOI":"10.1111\/j.1365-3083.1981.tb00178.x","type":"journal-article","created":{"date-parts":[[2006,6,30]],"date-time":"2006-06-30T15:34:39Z","timestamp":1151681679000},"page":"1-13","update-policy":"http:\/\/dx.doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Distribution of Surface, Cytoplasmic and Secreted IgG Subclasses in Human Lymphoblastoid Cell Lines and Normal Peripheral Blood Lymphocytes"],"prefix":"10.1111","volume":"14","author":[{"given":"J.
