INDEXPlant lectin / Plant / Fruit / Hololectins / Mannose/glucose-binding lectins
CHARACTERIZATIONBanLec-I was found to be very effective as a probe in detecting glycoproteins, e.g. on nitrocellulose blots. For BanLec-I effect on IgG4, see: Int Arch Allergy Immunol. 1992;97(1):17-24. Banana lectin found in prepared food was found to be autoclave resistant, and indeed was enhanced by heating. See: Appl Environ Microbiol 1981 (41) 880-888
BIOACTIVITYThe lectin does not agglutinate untreated human or sheep erythrocytes but does agglutinate rabbit red blood cells. Banana lectin also stimulates T-cell proliferation. See: Biochem J 1990 (272);721-726 IgG4 antibodies to banana were found to occur more frequently than expected. The most imprtant antigen involved is the lectin BanLec-I. See: Inter Archiv Allergy Immunol 1992 (97); 17-24
