Cold-target inhibition results.
Cold-target inhibition proves the specificity of the LP-1–specific CTLs. The myeloma cell line LP-1 was used as a target in a 51Cr-release assay. The antigen specificity of the CTLs was tested in the presence of unlabeled LP-1 or SK-OV-3 tumor cells as cold targets, with an inhibitor-target ratio of 20:1.
