Anti-TCEA1, ID (TCEA1, GTF2S, TFIIS, Transcription elongation factor A protein 1, Transcription elon

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. Applications: Suitable for use in Western Blot, Immunohistochemistry, ELISA, Recommended Dilution: ELISA: 1:1,000, Western Blot: 1:100-500, Immunohistochemistry: 1:10-50, 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. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap.
