Anti-MKI67 Antibody

Rabbit polyclonal IgG preparations targeting MKI67 are widely used proliferation markers in cancer biology and tumor pathology. This unconjugated reagent from Antibodies.com is raised in rabbit and validated for Western blot, immunohistochemistry, and immunofluorescence workflows on human samples. MKI67 encodes the nuclear Ki-67 antigen, which is expressed during the G1, S, G2, and M phases of the cell cycle but absent in resting (G0) cells, making it a standard index of actively dividing cells in tumor grading, prognostic studies, and cell-cycle research. The antibody is supplied as 50 µl of liquid in a vial, ready to be titrated for staining of formalin-fixed paraffin-embedded tissue sections, immunoblotting of proliferating cell lysates, or immunofluorescence imaging of cultured human cells. Polyclonal recognition of multiple epitopes on the Ki-67 protein helps sustain signal across varied sample preparations and supports broad reactivity across human tissue types encountered in research and translational studies.
