Rabbit Monoclonal, RTU. Intended for in vitro diagnostic (IVD) use. The Ki-67 antigen is a nuclear, non-histone protein that is present in proliferating cells. In general, Ki-67 is a good marker of proliferating cell populations. Anti-Ki-67 labeling index has been shown to be a good marker to grade neoplasms, including colon carcinoma, breast carcinoma, and lymphoma. References 1. McKeever P, et al.
