Flow Cytometry analysis of CACO-2 cells using anti-SAPK4 antibody (PB9721).
Overlay histogram showing CACO-2 cells stained with PB9721 (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-SAPK4 Antibody (PB9721, 1 μg/1x106 cells) for 30 min at 20°C. Fluoro488 conjugated goat anti-rabbit IgG (BA1127, 5-10 μg/1x106 cells) was used as secondary antibody for 30 minutes at 20°C. Isotype control antibody (Green line) was rabbit IgG (1 μg/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 MAPK13
MAPK13 (Mitogen-Activated Protein Kinase 13), also called p38-DELTA or Stress-Activated Protein Kinase 4 (SAPK4), is an enzyme that in humans is encoded by the MAPK13 gene. The protein encoded by this gene is a member of the MAP kinase family. MAP kinases act as an integration point for multiple biochemical signals, and are involved in a wide variety of cellular processes such as proliferation, differentiation, transcription regulation and development. This kinase is closely related to p38 MAP kinase, both of which can be activated by proinflammatory cytokines and cellular stress. MAP kinase kinases 3, and 6 can phosphorylate and activate this kinase. Transcription factor ATF2, and microtubule dynamics regulator stathmin have been shown to be the substrates of this 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.
