Con A is not blood group specific but has an affinity for terminal α-D-mannosyl and α-D-glucosyl residues. Ca2+ and Mn2+ ions are required for activity. Con A dissociates into dimers at pH 5.6 or below. Between pH 5.8 and pH 7.0, Con A exists as a tetramer; above pH 7.0 higher aggregates are formed. Con A exhibits mitogenic activity which is dependent on its degree of aggregation. Succinylation results in an active dimeric form which remains a dimer above pH 5.6.

Suspension in 0.1 M acetate buffer, pH 6.0, containing 1 M NaCl, and 1 mM each of CaCl2 , MgCl2, and MnCl2
Nota de análisis
Where reported, agglutination activity is expressed in μg/ml and is determined from serial dilutions in phosphate buffered saline, pH 6.8, containing Ca2+ and Mn2+ of a 1 mg per mL solution. This activity is the lowest concentration to agglutinate a 2% suspension of human erythrocytes after 1 hr incubation at 25 °C.
Cudrania tricuspidata is one of the most omnipresent traditional herbal drugs for anti-inflammation and anti-tumor. The purpose of the present study was to determine whether the CTB glycoprotein regulates the inflammatory reaction stimulated by bisphenol A (BPA) in human mast

CyrA, an extracellular matrix (slime sheath), calmodulin (CaM)-binding protein in Dictyostelium discoideum, possesses four tandem EGF-like repeats in its C-terminus and is proteolytically cleaved during asexual development. A previous study reported the expression and localization of CyrA cleavage products CyrA-C45

This study investigated the inhibitory effect of a glycoprotein isolated from Cudrania tricuspidata Bureau (CTB glycoprotein) on di(2-ethylhexyl) phthalate (DEHP)-induced mast cell degranulation and related signaling cascade in RBL-2H3 cells. This experiment evaluated the intracellular Ca(2+) level, and the activities
