Relationships between E-values and concentration of telomerase extracts or injection-time. (A) Relationship between E-values and concentration of telomerase extracts. A colon cancer cell line, SW480 (open circles) and a normal fibroblast cell (CSC 2F0-C25, closed circles). (B) Sensorgrams of SW480 for 1- (a), 5- (b), 10- (c) and 30- min (d) injections at 0.1 mg/ml. (C) E-values with several different injection times, used in human cancer cell lines (open circles, T47-D; open squares, MCF7; open triangles, SW480) and normal fibroblast cell lines (closed squares, CSC 2F0-C25; closed triangles, ACBRI #469).
