PREPARATION OF ENRICHED IMMUNOGLOBULIN M AND IMMUNOGLOBULIN A FROM HUMAN PLASMA
As IgM and IgA-enriched preparations are needed to complete the immunotherapeutic spectrum, a simple procedure is described for the preparation of IgM and IgA enriched immunoglobulins. Fraction III which was prepared by cold ethanol fractionation was treated by octanoic acid followed by ethanol precipitation and ion-exchange chromatography using Sephadex DEAE A-50 and 0.1 M tris-D.35M NaCI ...
متن کاملAnticardiolipin Antibodies and Immunoglobulin M and A in Graves’ Disease
Background: Graves’ disease is an autoimmune disease, characterized by the presence of antibodies directed to TSH receptor or nearby regions as well as antibodies to double strands DNA (dsDNA) anticardiolipin and nuclear antibodies. This study evaluated anticardiolipin and rheumatoid factor, such as IgA and IgM antibodies in patients with Graves’ disease. Patients and methods: Anticardiolipin a...
متن کاملTransgene Expression of bcl-xL Permits Anti-immunoglobulin (Ig)–induced Proliferation in xid B Cells
Mutations in the tyrosine kinase, Btk, result in a mild immunodeficiency in mice (xid). While B lymphocytes from xid mice do not proliferate to anti-immunoglobulin (Ig), we show here induction of the complete complement of cell cycle regulatory molecules, though the level of induction is about half that detected in normal B cells. Cell cycle analysis reveals that anti-Ig stimulated xid B cells ...
متن کاملCritical elements of the immunoglobulin heavy chain gene enhancers for deregulated expression of bcl-2.
Translocation of the bcl-2 gene to the immunoglobulin heavy chain gene is the most common alteration in follicular lymphoma. The result is the deregulated expression of bcl-2 and increased resistance to cell death. Regulation of the immunoglobulin heavy chain gene is controlled in part by four DNase I-hypersensitive regions located 3' of the gene. Here, we show that these four enhancer regions ...
متن کاملHuman B cell differentiation. II. Pokeweed mitogen-responsive B cells belong to a surface immunoglobulin D-negative subpopulation
Surface immunoglobulin D (IgD)-positive lymphocytes precoated with monoclonal anti-delta antibody were selectively removed from blood mononuclear cell preparations by "panning" and by fluorescence-activated cell sorter. The depletion of sIgD+ cells did not significantly affect plasma cell responses to pokeweed mitogen PWM). PWM-responsive B cells lacking sIgD and mouse erythrocyte receptors pre...
