BINDING 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 کاملInhibition of intercellular adhesion by concanavalin A is associated with concanavalin A-mediated redistribution of surface receptors
The inhibition of adhesion between aggregates and layers of embryonic retinal cells by concanavalin A (Con A) and Con A-mediated rearrangements of Con A receptors on retinal cells were studied. A short incubation of aggregates and layers with 10 micrograms/ml Con A substantially reduced aggregate-to-layer adhesion in a subsequent assay without soluble lectin present. This effect of Con A was do...
متن کاملNonuniform distribution of concanavalin-A receptors and surface antigens on uropod-forming thymocytes
Uropods can form spontaneously in a variable fraction of mouse thymocytes incubated for 30--60 min in vitro at temperatures between about 8 degrees and 37 degrees C. The majority of the cells with a typical uropod are medium and large thymocytes. The "normal" distribution of concanavalin-A receptors and antigens recognized by a rabbit anti-mouse thymocyte serum was studied on these cells by ele...
