Anti-Ki-67 Antibody

Manufactured by Antibodies.com, this primary antibody is a rabbit polyclonal reagent raised against the Ki-67 nuclear proliferation marker, supplied in a 50 µl volume at a concentration of 1 mg/ml in PBS containing 0.1% sodium azide and 50% glycerol as stabilizers. The unconjugated antibody is produced in rabbit and purified to an estimated purity of greater than 95%, making it suitable for sensitive detection workflows where a clean secondary antibody conjugate is preferred. Validated for use in Western Blotting (WB), Immunohistochemistry (IHC), and Immunofluorescence (IF), the reagent reliably detects endogenous Ki-67 protein in human samples, supporting research applications in oncology, cell-cycle biology, and tissue-proliferation studies. As a polyclonal reagent, the antibody recognizes multiple epitopes on Ki-67, which generally enhances signal strength and tolerance to minor sample-to-sample variation when compared with monoclonal alternatives. The product is intended for Research Use Only and is recommended to be stored according to the standard Antibodies.com handling conditions for glycerol-containing antibody formulations, typically at -20 °C for long-term preservation with minimal freeze-thaw cycles. This Ki-67 antibody complements a broad catalogue of Antibodies.com primary reagents designed for reproducible performance across common immunodetection platforms, and it can be paired with HRP-, fluorophore-, or biotin-conjugated secondary antibodies depending on the experimental readout required.
