General description

Map kinase phosphatase-1 (MKP-1) is a protein that belongs to protein-tyrosine phosphatase family. It has a pivotal role in inhibiting p38 and subsequent destabilisation of pro-inflammatory mRNAs by GCs. It also has a crucial role in regulating MAP kinase and can inhibit fibroblast proliferation due to overexpression. Anti-MAP kinase phosphatase-1 (MKP-1) antibody can be used to study the differential tissue expression, specific activation requirements and for intracellular localization of MAP kinase phosphatases in normal and neoplastic cells and tissues. Rabbit anti-MAP kinase phosphatase-1 (MKP-1) antibody reacts specifically with MAP kinase phosphatase-1 (39 kD protein). The product has also shown reactivity for human.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, containing 15 mM sodium azide.


Anti-MAP kinase phosphatase-1 (MKP-1) antibody can be used in western blotting (diluted-1:5,000) using TPA-induced A431 whole cell extract. It can also be used in microarray.
