Printed in Great Britain Assembly of Immunoglobulin M BLOCKED THIOL GROUPS OF INTRACELLULAR 7 S SUBUNITS By BRIGITTE
We have shown previously that immunoglobulin M (IgM) is present within IgMforming cells mainly in its 7S subunit form (IgMs), whereas only fully assembled IgM pentamers are secreted. There is no spontaneous polymerization of intracellular IgMs in cell lysates, suggesting that the 7 S subunits had blocked cysteine residues. This suggestion was explored and confirmed in the present paper. Radioac...
متن کاملPREPARATION 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 ...

15 صفحه اولMutations in genes encoding sorting nexins alter production of intracellular and extracellular proteases in Aspergillus nidulans.
XprG, a putative p53-like transcriptional activator, regulates production of extracellular proteases in response to nutrient limitation and may also have a role in programmed cell death. To identify genes that may be involved in the XprG regulatory pathway, xprG2 revertants were isolated and shown to carry mutations in genes which we have named sogA-C (suppressors of xprG). The translocation br...
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...
