Profile of lectins binding to baculovirus-expressed human ZP1 273-551aa in ELISA. Microtitration plates were coated with the baculovirus-expressed recombinant ZP1273-551aa (open bar; 500 ng/well) and processed for evaluation of binding to 21 different biotinylated lectins in an ELISA as described in Methods. As an internal control, microtitration plates coated with same amount of E. coli-expressed recombinant human ZP1273-551aa (grey bar; unpublished observations) were also used. Values are expressed as absorbance obtained with various lectins binding to the respective recombinant protein, after deducting the non-specific binding of the lectins to the uncoated wells. Each bar represents a mean of duplicate experiments and standard deviation of the absorbance values. The lectins tested were GSL-I: Griffon simplicifolia lectin I, SBA: Soybean agglutinin, DSL: Datura stramonium lectin, PSA: Pisum sativum agglutinin, ConA: Concanavalin A, ECL: Erythrina cristagalli lectin, LCA: Lens culinaris agglutinin, DBA: Dolichos biflorus agglutinin, LEL: Lycopersicon esculentum lectin, PHA-L: Phaseolus vulgaris leucoagglutinin, UEA-I: Ulex europaeus agglutinin I, STL: Solanum tuberosum lectin, PHA-E: Phaseolus vulgaris erythroagglutinin, RCA: Ricinus communis agglutinin, VVA: Vicia villosa agglutinin, SJA: Sophora japonica agglutinin, PNA: Peanut agglutinin, S- WGA: Succinylated Wheat germ agglutinin, Jacalin, WGA: Wheat Germ agglutinin and GSL II: Griffonia simplicifolia lectin II.
