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 کاملDetermination of Superficial Clefts on Fragment of Antigen Binding in Human Immunoglobulin G by Computational Immunology
Background: Immunoglobulins (Igs) are protective glycoproteins specifically identify and eradicate microbes. Fragment of antigen binding (Fab) is a portion of antibody which binds to antigen and consists of one variable and one constant domain of one heavy and one light chain. Idiotypes, epitopes situated on Igs variable region, could be exploited to monitor and target malignant B cells and are...
متن کاملBinding of Clostridium difficile toxin A to human milk secretory component.
Toxigenic Clostridium difficile is isolated from a majority of healthy human infants. The exact mechanism of asymptomatic colonisation is unclear; however, previous studies in this laboratory have shown that components of both the immunoglobulin and non-immunoglobulin fractions of human milk bind to toxin A and prevent its interaction with hamster intestinal brush border membranes (BBMs). Secre...
متن کاملInfluence of secretory immunoglobulin A and purified secretory component on dextran-sucrase activity of Streptococcus mutans.
The net stimulation of dextransucrase EC 2.4.1.5) activity from Streptococcus mutans HS6 by dextran, secretory immunoglobulin A, or secretory component was investigated. Approximately equal stimulation resulted from treatment with these three components.
متن کاملThe amino-terminal domain of rabbit secretory component is responsible for noncovalent binding to immunoglobulin A dimers.
Rabbit secretory components (SC) constitute a family of markedly heterogeneous glycoproteins which are released in the secretions as free SC or as SC bound to polymeric immunoglobulins. The aim of this work was to determine the region of the SC polypeptides which is involved in IgA binding. The high and the low Mr forms of free SC (or IgA-dissociated bound SC) and the native secretory IgA compl...
