Product Overview
This rabbit polyclonal antibody recognizes transcription elongation factor SPT6 (gene SUPT6H) in human, monkey, mouse and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 199.1 kDa, and the supplier reports an observed band at about 250 kDa.
SPT6 (SUPT6H) is a histone H3-H4 chaperone that travels with elongating RNA polymerase II. By binding the polymerase and IWS1, it helps maintain chromatin structure behind the polymerase and links elongation to mRNA processing and export, and it is studied in transcription and chromatin regulation.

Immunogen
Recombinant human Spt6/SUPT6H fragment (Ala564–Gln1639), expressed in E. coli.
Reactivity Notes
The supplier lists reactivity with human, monkey, mouse and rat. UniProt places transcription elongation factor SPT6 in the nucleus. Tissue expression noted by UniProt (human): Ubiquitously expressed. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
