SKU:: 578583
Purity:: Purified by Protein G affinity chromatography.
Storage Conditions:: -20°C
Supplier:: United States Biological
Host:: Rabbit
Immunogen:: Recombinant protein corresponding to aa79-169 from human transcription elongation factor A protein 3.
Format:: Supplied as a liquid in 0.01M PBS, pH 7.4, 0.03% Proclin 300, 50% glycerol.
Extra Details:: 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'-terminal. Applications: Suitable for use in ELISA, Immunohistochemistry and Immunofluorescence. Other applications not tested. Recommended Dilution: Immunohistochemistry: 1:500-1:1000 Immunofluorescence: 1:200-1:500 Optimal dilutions to be determined by the researcher. Storage and Stability: May be stored at 4°C for short-term only. Aliquot to avoid repeated freezing and thawing. Store at -20°C. Aliquots are stable for 12 months after receipt. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
