特記事項（精製）First purified by protein G affinity chromatography. Then, the antibody fraction is peptide affinity purified in a 2 step procedure with the control and phosphorylated peptides. The phospho specific antibody is eluted with high and low pH buffers and neutralized immediately, followed by dialysis against PBS.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/100 - 1/500. Detects a band of approximately 91 kDa (predicted molecular weight: 91 kDa).
1/50 - 1/100.
機能Carries out a dual function: signal transduction and activation of transcription. Binds to the GAS element and activates PRL-induced transcription.
配列類似性Belongs to the transcription factor STAT family. Contains 1 SH2 domain.
翻訳後修飾Tyrosine phosphorylated in response to IL-2, IL-3, IL-7, IL-15, GM-CSF, growth hormone, prolactin, erythropoietin and thrombopoietin. Tyrosine phosphorylation is required for DNA-binding activity and dimerization. Serine phosphorylation is also required for maximal transcriptional activity.
細胞内局在Cytoplasm. Nucleus. Translocated into the nucleus in response to phosphorylation.
