The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
1/50 - 1/100. Perform heat mediated antigen retrieval via the pressure cooker method before commencing with IHC staining protocol.
1/500 - 1/1000. Detects a band of approximately 170 kDa (predicted molecular weight: 180 kDa).
功能Component of the Mediator complex, a coactivator involved in the regulated transcription of nearly all RNA polymerase II-dependent genes. Mediator functions as a bridge to convey information from gene-specific regulatory proteins to the basal RNA polymerase II transcription machinery. Mediator is recruited to promoters by direct interactions with regulatory proteins and serves as a scaffold for the assembly of a functional preinitiation complex with RNA polymerase II and the general transcription factors.
序列相似性Belongs to the Mediator complex subunit 1 family.
翻译后修饰Phosphorylated by MAPK1 or MAPK3 during G2/M phase which may enhance protein stability and promote entry into the nucleolus. Phosphorylated upon DNA damage, probably by ATM or ATR.
细胞定位Nucleus. A subset of the protein may enter the nucleolus subsequent to phosphorylation by MAPK1 or MAPK3.
Immunohistochemistry analysis of paraffin-embedded human breast carcinoma tissue using 1/50 ab64965, after antigen retrieval by boiling in a pressure cooker for 2-3 min. Polymer system was used for signal enhancing and DAB staining was performed for visualising the signal.
