A Co(III) derivative of concanavalin A
Biochemical and Biophysical Research Communications, 1979Abstract Co(III) has been stoichiometrically incorporated into jack bean concanavalin A. The Co(III) protein still possesses a binding site for an additional divalent transition metal ion which together with Ca(II) can induce the sugar binding ability. No H2O2 oxidation of Co(II) occurs with demetallized concanavalin A activated with Ca(II) and Co(II)

Adsorption of concanavalin a on human platelets
Annals of Biomedical Engineering, 1982A physiological cell surface adsorption system approach is investigated on human platelets utilizing mathematical modeling. Monodispersed washed platelets are freshly collected in an isotonic buffer as a suspension utilizing a gel filtration technique. Concanavalin A is used as a glycoprotein receptor adsorbate in the adsorption studies.

Concanavalin A is capable of activating platelets in a concentration-dependent manner as judged by [14C]serotonin secretion from prelabeled platelets. In contrast, succinyl concanavalin A does not induce platelet secretion. Concanavalin A treatment also results in a number of alterations in platelet macromolecules which are presumably associated with ...

The American review of respiratory disease, 1976
Concanavalin A-nonreactive polysaccharide and 2 concanavalin A-reactive polysaccharides of differing concanavalin A affinities that had been purified from culture filtrates of Mycobacterium tuberculosis were subjected to carbohydrate analysis by gas and gas-liquid chromatography.

Inhibition of cytotoxic T lymphocytes with concanavalin A
Cellular Immunology, 1980Abstract Increasing concentrations of concanavalin A (ConA) were found to increasingly inhibit immunologically specific cytotoxic T lymphocyte (CTL)-mediated cytolysis. Even concentrations of ConA that best enabled nonspecific cytolysis were found to inhibit immunologically specific cytolysis by the same population of effector cells.

Cross-linked derivatives of Concanavalin A
1987Publisher Summary This chapter describes methods for the preparation of covalently cross-linked mono-, di-, and tetravalent Concanavalin A derivatives, which do not undergo subunit exchange. Concanavalin A (Con A) is the most widely used lectin in immunology and cell biology. It activates T lymphocytes, leading to cell division, lymphokine production,

Studies on haptoglobin binding to concanavalin a
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1984Ascitic fluid haptoglobins 1-1, 2-1 and 2-2 and their tryptic glycopeptides were fractionated by affinity chromatography on Con A-Sepharose. Three peaks were obtained, corresponding to non-binding, weakly binding and strongly binding fractions. Concanavalin A-non-binding and concanavalin A-binding fractions of haptoglobin and of glycopeptide III 2-2 ...

Studies on the Combining Sites of Concanavalin A
1975The initial event in the biological activity of concanavalin A (Con A) involves binding of the protein to cell surface receptors. The nature and mechanism whereby such binding may occur is described in terms of cell surface carbohydrates and the demonstrated specificity of the protein.
