In cell migration assays, rhLM511 and rhLM521 strongly promoted migration of glioma cells (161 and 174 cells/field, respectively), melanoma cells (88 and 203 cells/field, respectively) and carcinoma cells (190 and 198 cells/field, respectively) when compared to HSA (1 cell/field for all cell lines). The gene discussed is ALB; the disease is melanoma.
