Cholesterol microcrystals associated with concanavalin A-binding glycoproteins contribute artifactually to nucleating activity assays.
Concanavalin A (Con A) affinity chromatography is the standard procedure to separate cholesterol nucleating biliary proteins from lipids and pigment. We observed that even after extensive washing following application of bile, lipid contaminants remain. We have determined the contribution of lipid contamination to cholesterol nucleation and assessed a modified procedure to remove lipids from th...
متن کاملBINDING SITES ON CONCANAVALIN A 399 Concanavalin
Equilibrium dialysis of concanavalin A against methyl c¢-D-mannopyranoside and methyl C¢-D-glucopyranoside conducted at 2 ° in the presence of I M NaC1 showed that concanavalin A is bivalent. A SCATCHARD plot of the data obtained gave straight lines for both sugars with observed association constants (K') of 1. 4. lO 4 1/mole for methyl ,¢-D-mannopyranoside and o.3" IO 4 1/mole for methyl ~¢-D-...
متن کاملComputational analysis of Concanavalin A binding glycoproteins of human seminal plasma
Glycoproteins have immense clinical importance and comparative glycoproteomics has become a powerful tool for biomarker discovery and disease diagnosis. Seminal plasma glycoproteins participate in fertility related processes including sperm-egg recognition, modulation of capacitation and acrosome reaction inhibition. Affinity chromatography using broad specificity lectin such as Con A is widely...
متن کاملConcanavalin A-captured glycoproteins in healthy human urine.
Both the urinary proteome and its glycoproteome can reflect human health status, and more directly, functions of kidney and urinary tracts. Because the high abundance protein albumin is not N-glycosylated, the urine N-glycoprotein enrichment procedure could deplete it, and urine proteome could thus provide a more detailed protein profile in addition to glycosylation information especially when ...
متن کاملa comparative study of language learning strategies employmed by bilinguals and monolinguals with reference to attitudes and motivation
هدف از این تحقیق بررسی برخی عوامل ادراکی واحساسی یعنی استفاده از شیوه های یادگیری زبان ، انگیزه ها ونگرش نسبت به زبان انگلیسی در رابطه با زمینه زبانی زبان آموزان می باشد. هدف بررسی این نکته بود که آیا اختلافی چشمگیر میان زبان آموزان دو زبانه و تک زبانه در میزان استفاده از شیوه های یادگیری زبان ، انگیزه ها نگرش و سطح مهارت زبانی وجود دارد. همچنین سعی شد تا بهترین و موثرترین عوامل پیش بینی کننده ...
