DESCRIPTION
(1) FORM
Affinity purified, off-white lyophilised powder.
(2) BIOCHEMICAL / PHYSIOLOGICAL PROPERTIES
Con A is not blood group specific, has an affinity for terminal α-D-mannose and α-D-glucose residues and requires the presence of Ca2+ and Mn2+ for activity. Con A exists in dimeric (pH < 5.6), tetrameric (pH between 5.6 and 7.0) and aggregate (pH > 7.0) forms. An active dimer above pH 5.6 can be generated by succinylation. Con A exhibits mitogenic activity which is dependent upon its degree of aggregation.

(3) PROPERTIES
Activity: 20 μg/mL
Electrophoretic purity: Electrophoresis was preformed using a 14% acrylamide gel.
UV absorbance: In 100 mM NaCl; λmax = 275.8; E1% = 13.7.
Solubility: Slightly hazy, colourless solution at 10 mg/mL in water.
Activity note: Activity is determined using a twofold serial dilution of 1 mg/mL solution of
Con A in PBS* (8.0 g NaCl, 0.3 g KCl, 0.2 g KH2PO4/L; pH 7.2) containing 1
mM Ca2+ and 1 mM Mn2+. The activity is expressed as the lowest concentra-
tion to give agglutination of a 2% suspension of human red blood cells (type O)
in PBS* after 1 hr incubation at room temperature.
(4) STORAGE / STABILITY / SAFETY
Storage temperature: -20ºC
Shelf life: > 3 years at -20ºC
Safety statement: 22-24 / 25
