Phospho-PAK1/2/3 (Ser141) Polyclonal Antibody - FAQs

Do you have phospho-specific antibodies against PAK1/2/3?

Yes, Thermo Fisher Scientific offers several antibodies against PAKs and their phosphorylated forms. These products include antibodies which react with pSer141, the autophosphorylation site in the SH2 domain of PAK (Cat. No. 44-940G). Also, see Cat. No 44942G, which reacts with PAK1/2/3 only when it is phosphorylated at Thr423. This important residue is located in the kinase activation loop.
