Research Abstract

We investigated an optimized procedure for the efficient isolation of melanoma cells labeled with HMW-MAA (High-Molecular Weight Melanoma-Associated Antigen) -specific antibodies and/or B7-H3-specific antibodies from the peripheral blood using immunomagnetic beads and fluorescence-activated cell sorting (FACS). Compared with the single-labeling method of melanoma cells using HMW-MAA or B7-H3 antibodies, the double-labeling method using HMW-MAA and B7-H3 antibodies earned high yield.These results suggest that the double-labeling method using HMW-MAA and B7-H3 antibodies is useful for isolating melanoma cells from peripheral blood in patients with melanoma.
