Product Overview
This rabbit polyclonal antibody recognizes mitogen-activated protein kinase 13 (gene MAPK13) in rat, mouse and human samples and is validated for Western blot. The predicted molecular weight is 42.1 kDa, and the supplier reports an observed band at about 170 kDa.
p38δ (MAPK13) is one of the four p38 MAP kinases, activated by MKK3 and MKK6 in response to stress and inflammatory signals. It is expressed in tissues such as skin, lung and immune cells and is studied in keratinocyte differentiation, inflammation and metabolic regulation.

|---|
Samples with a confirmed band (WB): PANC cells, COLO320 cells, Jurkat cells.
Recommended loading (WB): 20–40 µg of total protein per lane.
Immunogen
Synthetic peptide from the C-terminal region of human SAPK4. It differs from the rat and mouse sequences at one residue.
Reactivity Notes
The supplier lists reactivity with rat, mouse and human. Tissue expression noted by UniProt (human): Expressed in testes, pancreas, small intestine, lung and kidney. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
