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).

100 µl total IgY fraction in PBS + 10 mM NaN3. Adequate amount of material to conduct 10-mini Western Blots.

Recommended that the undiluted antibody be aliquoted into smaller working volumes (10-30 uL/vial depending on usage) upon arrival and stored long term at -20° C or -80° C, while keeping a working aliquot stored at 4° C for short term. Avoid freeze/thaw cycles. Stable for at least 1 year.

Immunostaining of HeLa cells showing specific labeling of Ki-67 (catalog #1007-Ki67, 1:2000, red) present in cytoplasmic microtubules. Additional immunostaining done with β-tubulin in green and nuclear staining with DAPI (blue). During cell cycle Ki-67 protein is predominantly expressed in the nucleoli of cells during mitosis and interphase, and is not present during quiescence.
