Antigen/Purification: ExpandCollapse

The antigen is recombinant human Ki-67 purified from E. coli.

The antibody is Total IgY fraction.

Biological Significance: ExpandCollapse

Ki-67 is a nuclear protein that is  considered to be essential for cellular proliferation since it is expressed only in active phases of the cell cycle (G1, S, G2 and mitosis) but not in resting phase G0 (Scholzen & Gerdes 2000).  Ki-67 antibodies have therefore been widely used as markers of cell growth. Ki-67 has further been identified as a predicative and prognostic marker in breast, lung, cervical and other cancers (Yerushalmi et al., 2010; Folescu et al., 2018; Das et al., 2018).
