TriPath Imaging Inc.

TriPath Imaging Inc. of Burlington, N.C., has received the FDA’s 510(k) approval to use the Ki-67 cell proliferation biomarker with the Ventana Image Analysis System from Ventana Medical Systems Inc. of Tucson, Ariz. The biomarker enables pathologists to determine the percentage of tumor cells that are actively dividing with precise quantitative measurements of the biomarker’s expression in breast biopsy samples. The approach is expected to aid scientists in further investigations into the correlation between proliferation rate and survival.
