Ki-67, Cell Cycle Marker (MIB-1)Catalog number: KI500
In retrospective studies the intensity of staining and the frequency of Ki-67 expression in cell nuclei was interpreted as a prognostic factor for the malignancy of tumours (Gerdes et al., 1987). Ki-67 Protein is a nuclear protein, which is ubiquitous present during cell division, that means in all phases of mitosis (S1, G1, G2 and M phase). The protein is strongly exprimed in proliferating tissues e.g. embryonal tissue and rapidly growing tumours. Ki-67 nuclear protein.
Immunogen: Human nuclear Ki-67 antigen
Antibody solution in stabilizing phosphate buffer pH 7.3. Contains 0.09 % sodium azide**. The volume is sufficient for at least 50 immunohistochemical tests (100 µl working solution / test). Use appropriate antibody diluent e.g. BIOLOGO Art. No. PU002, if further dilution is required.
