Species: Mouse Immunogen: Human KAL cells derived from lymph node metastasis of malignant melanoma Clone: KBA.62 Isotype: IgG1, kappa Species Reactivity: Human. Others not known. Positive Control: Melanoma Cellular Localization: Cell Surface Specificity: KBA.62 is a novel anti-melanoma antibody. It reacts positively against melanocytic tumors but not against other tumors, thus demonstrating specificity and sensitivity. Moreover, it reacts positively against junctional nevus cells but not intradermal nevi, and against fetal melanocytes but not normal adult melanocytes.
