study of cohesive devices in the textbook of english for the students of apsychology by rastegarpour
this study investigates the cohesive devices used in the textbook of english for the students of psychology. the research questions and hypotheses in the present study are based on what frequency and distribution of grammatical and lexical cohesive devices are. then, to answer the questions all grammatical and lexical cohesive devices in reading comprehension passages from 6 units of 21units th...
Secondary structure of the immunoglobulin J chain.
J chain is a 137-residue polypeptide that is covalently linked to polymeric immunoglobulins and participates in their synthesis and transport to external secretions. To clarify these roles, the secondary structure of J chain was characterized by computer-assisted analyses of human and mouse sequences and by circular dichroism measurements of the isolated J chain. The secondary-structure profile...
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 ...
متن کاملImmunoglobulin formation in B lymphoid cells.
A considerable amount is known about Ig biosynthesis by mature plasma cells, which form large amounts of Ig for secretion from the cell. A brief summary is given of the formation of light (L) and heavy (H) chains by polyribosomes aligned on the endoplasmic reticulum and the rapid assembly of the chains into 7S molecules (H2L2) by disulphide bonding. There is a time-ordered secretion from the ce...
متن کاملAn anchor-minus form of the polymeric immunoglobulin receptor is secreted predominantly apically in Madin-Darby canine kidney cells
The polymeric immunoglobulin receptor is expressed in a variety of polarized epithelial cells. Newly made receptor travels first to the basolateral surface. The receptor is then endocytosed, transported across the cell in vesicles, and exocytosed at the apical surface. We have now deleted the membrane spanning and cytoplasmic portions of the receptor by site-directed mutagenesis, thus convertin...
