MKI67 encodes the Ki-67 protein, also known as Antigen KI-67. A nuclear phosphoprotein, it is expressed in active cell cycle phases (G1, S, G2, M) but absent in quiescent G0 cells, serving as a gold-standard marker for cell proliferation. It interacts with cyclins and cyclin-dependent kinases (CDKs) to regulate cell cycle progression, linking to core cell cycle signaling pathways.
Overexpression of Ki-67 correlates with high tumor aggressiveness in solid cancers (breast, lung, colorectal) and hematological malignancies. While direct Ki-67 inhibitors are unapproved, CDK4/6 inhibitors (e.g., palbociclib) reduce proliferation in Ki-67-high tumors. Preclinical studies explore monoclonal antibodies for Ki-67-targeted imaging and therapy to enhance cancer diagnosis and treatment.
Recombinant Human Proliferation marker protein Ki-67 (MKI67), partial (CSB-EP014597HU1)
Validated Data
(Tris-Glycine gel) Discontinuous SDS-PAGE (reduced) with 5% enrichment gel and 15% separation gel.
MKI67 Recombinant Monoclonal Antibody (CSB-RA984483A0HU)
Validated Data
IHC image of CSB-RA984483A0HU diluted at 1:100 and staining in paraffin-embedded human tonsil tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a Goat anti-rabbit polymer IgG labeled by HRP and visualized using 0.65% DAB.
Overlay Peak curve showing Hela cells stained with CSB-RA984483A0HU (red line) at 1:50. The cells were fixed in 4% formaldehyde and permeated by 0.2% TritonX-100. Then 10% normal goat serum to block non-specific protein-protein interactions followed by the antibody (1µg/1*106cells) for 45min at 4℃. The secondary antibody used was FITC-conjugated Goat Anti-rabbit IgG(H+L) at 1:200 dilution for 35min at 4℃.Control antibody (green line) was rabbit IgG (1µg/1*106cells) used under the same conditions. Acquisition of >10,000 events was performed.
