Abstract
Concanavalin A (con A) is a potent inhibitor of coagulant activity of native tissue factor. Coagulant activity is recovered by addition of alpha-methyl-D-glucoside to inhibited tissue factor. Inclusion of alpha-methyl-D-glucose during incubation of con A with tissue factor preserves coagulant activity. These data suggest that con A interacts reversibly with a carbohydrate residue in such a way as to inhibit coagulant activity of the molecule. Purified tissue factor apoprotein has been recombined with mixed brain phospholipids or purified phospholipids (phosphatidyl ethanolamine or a mixture of phosphatidyl choline with phosphatidyl serine). These preparations were also completely but reversibly inhibited by con A. Thus, purified tissue factor apoprotein appears to donate the affected carbohydrate residue.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
