A novel lectin with a molecular mass of 24.3kDa, designated Lunatin, was isolated from edible seeds of Phaseolus lunatus billb. The purification scheme consisted of ammonium sulfate precipitation, affinity chromatography, ion exchange chromatography, and gel filtration chromatography. The lectin is

Cells from the human leukemia cell line HL-60 undergo terminal monocyte-like differentiation after exposure to either the active circulating form of vitamin D3, 1,25-dihydroxyvitamin D3 [1,25-(OH)2D3], or phorbol 12-myristate 13-acetate. Little is known about the genes that regulate monocytic

1. KAR-2 (3"-(beta-chloroethyl)-2",4"-dioxo-3,5"-spiro-oxazolidino- 4-deacetoxy-vinblastine), is a bis-indol derivative; catharantine is coupled with the vindoline moiety which contains a substituted oxazolidino group. Our binding studies showed that KAR-2 exhibited high affinity for bovine purified
