Staining of paraffin embedded human lymph node with Human anti Ki-67
A) Immunohistochemistry (paraffin sections) was carried out using the Human anti-Ki67 antibody carrying a His-6 tag (HCA006) at 1/50 on Human Lymph Node LN6 Hodgkins tissue. Antigen retrieval was conducted using citrate buffer (pH6) treatment. For detection, HRP conjugated Mouse anti-Histidine tag (MCA5995P ) was applied at 1/50 (brown). B) As a negative control, Mouse anti-Histidine tag (MCA5995P ) was applied at 1/50 on Human Lymph Node LN6 Hodgkins tissue that had been treated in the same way. Sections were counterstained with Hematoxylin (blue). Images were visualized at x20 zoom

    • Human anti Ki67 antibody, clone AbD02531, recognizes the sequence GFKELFQ, which can be found eight times on the human Ki67 protein: Amino acid positions 1104-1110, 1226-1232, 1348-1354, 1590-1596, 1956-1962, 2078-2084, 2318-2324, and 2439-2445.

      Ki-67 antigen is expressed in proliferating cells but not in quiescent cells. Expression of this antigen occurs preferentially during late G1, S, G2, and M phases of the cell cycle, while in cells in G0 phase the antigen cannot be detected. Consequently, Ki-67 antigen expression is used in tumor pathology to detect proliferating cells in neoplastic diseases. In cultured cells, Ki-67 is expressed in the nucleolus of interphase cells.
      The Ki-67 gene contains 15 exons. The Ki-67 repeat region, within which there is a 22-amino acid Ki-67 motif, is encoded by exon 13. The shorter isoform lacks exon 7. Northern blot analysis revealed multiple transcripts ranging from approximately 8.9 to 12.5 kb in proliferating but not quiescent cells. Immunoblot analysis showed expression of 320- and 359-kDa proteins. Sequence analysis predicted that the short-lived 2,896- and 3,256-amino acid protein isoforms contain potential nuclear targeting signals, over 200 potential phosphorylation sites, 19 N-myristoylation sites, 3 amidation sites, and numerous PEST sites. Antisense oligonucleotides inhibited cellular proliferation in a dose-dependent manner, suggesting that Ki-67 protein expression may be an absolute requirement for cell proliferation. Clone AbD02531 is also known as clone 2531.

    • Product Form
      Bivalent human recombinant Fab selected from the HuCAL® GOLD phage display library. Expressed in E. coli and purified using NiNTA affinity chromatography. This Fab fragment is dimerized via a helix-turn-helix motif. The antibody is tagged with a myc-tag (EQKLISEEDL) and a his-tag (HHHHHH) at the C-terminus of the antibody heavy chain -- Liquid.

    • Immunogen
      Peptide derived from the human Ki-67 protein. Sequence GFKELFQTPG, coupled via a C-terminal cysteine to carrier proteins.
    • Activity
      Activity was tested by indirect ELISA: The Ki-67 antigen peptide was coupled to human transferrin carrier protein. The coupled antigen (5 μg/ml) plus unrelated control proteins were immobilized on a microtiter plate. Specific binding was monitored by first adding HCA006 (2 μg/ml), then adding a secondary antibody (goat anti-human F(ab')2 fragment specific, AP conjugate. 1:5000 diluted). A fluorescent signal was created by adding the AP sub-strate Attophos. The signal on the antigen is at least 5-fold above background, whereas the signal on the control antigens is less than 1.5-fold above background.
