<qa>  What is the antibody that provides direct visualization and semi-quantification of the protein expression throughThe anti Ki-67 is a semi-quantitative immunohistochemical IHC assay to identify the Ki-67 protein expressions in formalin-fixed, paraffin-embedded human breast cancer tissue specimens. Results from the Ki-67 test is indicated as an aid in the assessment of the protein status of breast cancer patients. While the p53 kit provides the antibody that offer direct visualization and semi-quantification of the protein expression through a brightfield microscope, the GenASIs GoPath system is designed to complement the routine workflow of the pathologist in the analysis and review of immunohistochemically stained histologic slides.
