Specificity of mAbs KM1730 and KM1732 against Flt-1.

(A) Flow cytometric analysis of the cell binding of antihuman Flt-1 mAbs, KM1730 and KM1732. NIH 3T3/Neo, NIH 3T3/Flt-1, and NIH 3T3/KDR cells were stained with KM1730, KM1732, or control mouse IgG1 mAb and analyzed by flow cytometry. (B) Flow cytometric analysis of the cell binding of antihuman KDR mAbs, KM1992 and KM1995.
