PA1-018 detects phosphorylated heat shock protein 27(hsp27) from rat and human tissue tissues.
PA1-018 has been successfully used in Western blot, immunoprecipitation, immunofluorscence, immunocytochemistry and immunohistochemistry procedures. Immunocytochemical staining of phospho-hsp27 (Ser15) in HeLa cells with this antibody results in cytoplasmic staining.
The PA1-018 immunogen is a synthetic phosphopeptide corresponding to the residues L(10) L R G P (pS) W D P F R C(21) of human HSP27. The immunizing peptide is 81% homologous in mice, rats, and hamsters. This peptide (Cat. # PEP-187) is available for use in neutralization and control experiments.
HSP27 also referred to as the Estrogen-Regulated 24K protein and HSP28, is one of several small heat shock proteins (HSP) produced by all organisms studied. HSP27 synthesis is induced by elevated temperature, as well as estrogen in hormone responsive cells. Interestingly, human HSP27 also shares greater than 50% homology with low molecular weight Drosophila HSP's and mammalian a-crystalline lens protein. Because of the estrogen responsive nature of HSP27, this protein has been studied extensively in human estrogen responsive tissues such as cervix, endometrium and breast tissue. This work has led to the suggestion that HSP27 may be a useful marker in classifying various hormone sensitive tumors.
