Flow Cytometry analysis of A431 cells using anti-S100A9 antibody (PB9677).
Overlay histogram showing A431 cells stained with PB9677 (Blue line). To facilitate intracellular staining, cells were fixed with 4% paraformaldehyde and permeabilized with permeabilization buffer. The cells were blocked with 10% normal goat serum. And then incubated with rabbit anti-S100A9 Antibody (PB9677, 1μg/1x106 cells) for 30 min at 20°C. DyLight®488 conjugated goat anti-rabbit IgG (BA1127, 5-10μg/1x106 cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1μg/1x106) used under the same conditions. Unlabelled sample without incubation with primary antibody and secondary antibody (Red line) was used as a blank control.

Background of S100A9
S100 calcium-binding protein A9 (S100A9), also known as migration inhibitory factor-related protein 14 (MRP14) or calgranulin B, is a protein that in humans is encoded by the S100A9 gene. S100-A9 is a member of the S100 family of proteins containing 2 EF hand calcium-binding motifs. And S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. This protein may function in the inhibition of casein kinase.

Antibody Homology Across Species
The results generated by this homology analysis tool for commonly used animal species are shown below. For unlisted species, please refer to the homology analysis between the immunogen sequence and the corresponding species.
A homology of ≥90% is recommended. Generally, higher homology indicates a greater potential for cross-species reactivity. However, protein expression levels may vary among different species, tissues, and cell types. Therefore, the homology analysis results are for reference only and do not guarantee antibody cross-reactivity or experimental performance.
