Product Overview
This rabbit polyclonal antibody recognizes dual specificity protein phosphatase 1 (gene DUSP1) in human samples and is validated for Western blot and flow cytometry. The predicted molecular weight is 39.3 kDa, and the supplier reports an observed band at about 40 kDa.
DUSP1 (also called MKP-1) is a dual-specificity phosphatase that removes phosphate from both threonine and tyrosine residues of MAP kinases. It is rapidly induced by stress and growth factors, provides negative feedback on MAPK signaling, and is widely studied in inflammation and stress responses.

Immunogen
Synthetic peptide from the N-terminal region of human MKP-1/DUSP1. Sequence identity with the mouse and rat orthologs: 96.3%.
Reactivity Notes
The supplier lists reactivity with human. UniProt places dual specificity protein phosphatase 1 in the nucleus. Tissue expression noted by UniProt (human): Expressed at high levels in the lung, liver placenta and pancreas. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
