Recombinant protein corresponding to human Ki67 expressed in E. coli. (Position: K2860-I3256).

Ki-67(Proliferation-related Ki-67 antigen), also known as MKI67 or KIA, is a protein that in humans is encoded by the MKI67 gene. From study of a panel of human-rodent somatic cell hybrids, it has been demonstrated that a gene involved in the expression of the MKI67 antigen is located on chromosome 10. By in situ hybridization, Fonatsch et al. (1991) regionalized the MKI67 gene to chromosome 10q25-qter. By FISH, Traut et al. (1998) mapped the mouse Mki67 gene to chromosome 7F3-F5. Antigen KI-67 is a nuclear protein that is associated with and may be necessary for cellular proliferation. Furthermore it is associated with ribosomal RNA transcription. Inactivation of antigen KI-67 leads to inhibition of ribosomal RNA synthesis.

Applications:
Suitable for use in Western Blot, Immunohistochemistry and Immunocytochemistry. Other applications not tested.

Recommended Dilution:
Western Blot: 0.1-0.5ug/ml, the detection limit is ~0.25ng/lane under reducing conditions.
Immunohistochemistry (paraffin): 0.5-1ug/ml, boiling the paraffin sections in 10mM citrate buffer, pH 6.0, for 20 mins is required for the staining of formalin/paraffin sections.
Immunocytochemistry: 0.5-1ug/ml
Optimal dilutions to be determined by the researcher.

Storage and Stability:
Lyophilized and reconstituted products are stable for 12 months after receipt at -20°C. Reconstitute with sterile ddH2O. Aliquot to avoid repeated freezing and thawing. Store at -20°C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
