LGALS8, also known as prostate-specific membrane antigen (PCTA1), is an additional prostate-specific antigen that is overexpressed only in malignant tumors and therefore is a more specific identifier of malignancies. It is a member of the galectin gene family which mediates both cell-cell and cell matrix interactions in a manner similar to the selectin subgroup of C-type lectins. Recombinant corresponding to aa1-379 of human LGALS8 protein, fused to His-tag at N-terminus, expressed in E.coli. Biological activity: The ED50 for this effect is is 5-10ug/ml, measured by its ability to agglutinate human red blood cells.
