Description

Description: The monoclonal antibody 20Raj1 recognizes the human Ki-67 protein. Two isoforms of Ki-67 exist, a 345 and 395 kDa form that are expressed in dividing cells. Ki-67 is expressed in all cell types and is detectable during active phases of the cell cycle (G1, S, G2, and mitosis) but is absent from resting cells (G0). During interphase, Ki-67 expression is localized to the nucleus but redistributes to the chromosomes during mitosis and has specifically been found to associate with heterochromatin-bound proteins such as chromobox protein homolog 3 (CBX3). In studies of tumor cells, Ki-67 expression has been used as a marker for determining the fraction of proliferating cells within a given population of tumor cells. This monoclonal antibody 20Raj1 recognizes canine Ki-67. Applications Reported: This 20Raj1 antibody has been reported for use in intracellular staining followed by flow cytometric analysis, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, microscopy, and immunocytochemistry. Applications Tested: This 20Raj1 antibody has been tested by intracellular staining of normal human peripheral blood cells using the Foxp3/Transcription Factor Buffers Set (Product # 00-5523-00) and protocol. Please see Best Protocols Section (Staining intracellular Antigens for Flow Cytometry) for staining protocol (refer to Protocol B: One-step protocol for intracellular (nuclear) proteins. This can be used at less than or equal to 0.125 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. The 20Raj1 antibody has also been tested by immunocytochemistry of fixed and permeablilized cells and can be used at less than or equal to 5 µg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Filtration: 0.2 µm post-manufacturing filtered.

Figure 1 PfRH5 vaccination with the ChAd63-MVA platform induces greater activation of total circulating CD8 + and CD4 + T cell populations, while the protein/AS01 B platform elicits a more sustained increase in cTfh-phenotype cells PBMCs from days 0, 7, 14, and 63 were stained ex vivo and analyzed using the gating strategies shown in Figures S1-S3 . (A and B) Increases at day 63 in activated CD38 + Ki67 + cells within total CD8 + and CD4 + T cells (A) or Th1 (CXCR3 + CCR6 - ), Th2 (CXCR3 - CCR6 - ), and Th17 (CXCR3 - CCR6 + ) CD4 + T cell subsets (B) were compared between platforms following subtraction of day 0 CD38 + Ki67 + frequencies in paired samples. (C-E) Frequencies of total cTfh cells defined as CXCR5 + (C) or CXCR5 + PD1 + (D) cells within the CD45RA - CD4 + T cell population were compared between platforms and the frequency of cTfr cells within total cTfh cells (defined as the CD25 + Foxp3 + subset) (E). All of the available samples are plotted (ChAd63-MVA/protein/AS01 B ): day 0, n = 15/54; day 7, n = 15/24; day 14, n = 15/54; day 63, n = 12/20. For intra-trial comparisons (E), only vaccinees with all 4 time points were analyzed: ChAd63-MVA, n = 12, protein/AS01 B , n = 17. Comparisons were performed with Mann-Whitney tests (between trials) or Friedman tests with Dunn's correction for multiple comparisons (within trials comparing day 0 to post-vaccination time points). *p < 0.5, **p < 0.01, and ***p < 0.001. In all of the panels, each point represents a vaccinee.
