Product Overview
This rabbit polyclonal antibody recognizes transcription initiation factor TFIID subunit 8 (gene TAF8) in human, mouse and rat samples and is validated for Western blot, ICC/IF, flow cytometry and ELISA. The predicted molecular weight is 34.3 kDa, and the supplier reports an observed band at about 34 kDa.
TAF8 is a histone-fold subunit of the general transcription factor TFIID that, with TAF5, forms one of its structural modules and helps incorporate TAF10. It supports both basal and activator-driven transcription and has been implicated in adipocyte differentiation and early embryo survival.

Reactivity Notes
The supplier lists reactivity with human, mouse and rat. UniProt places transcription initiation factor TFIID subunit 8 in the nucleus and cytoplasm. The samples tested by the supplier (listed above) are a practical starting point for positive controls.
