The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use a concentration of 0.5 µg/ml. Detects a band of approximately 40 kDa (predicted molecular weight: 39 kDa). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
Use at an assay dependent concentration.
功能Necessary for efficient RNA polymerase II transcription elongation past template-encoded arresting sites. The arresting sites in DNA have the property of trapping a certain fraction of elongating RNA polymerases that pass through, resulting in locked ternary complexes. Cleavage of the nascent transcript by S-II allows the resumption of elongation from the new 3'-terminus.
序列相似性Belongs to the TFS-II family. Contains 1 TFIIS central domain. Contains 1 TFIIS N-terminal domain. Contains 1 TFIIS-type zinc finger.
Staining of parafin-embeded sections of human pancreas cells with ab26141 (4-8 ug/ml). Positive label on epithelial cells of pancreatic acinus indicated with arrows.
