The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
Use at 2-10 µg/mg of lysate.
Application notesIs unsuitable for WB.
FunctionTranscriptional regulator which functions as a general RNA polymerase II transcription inhibitor. In cooperation with 7SK snRNA sequesters P-TEFb in a large inactive 7SK snRNP complex preventing RNA polymerase II phosphorylation and subsequent transcriptional elongation. May also regulate NF-kappa-B, ESR1, NR3C1 and CIITA-dependent transcriptional activity.
Tissue specificityUbiquitously expressed with higher expression in placenta. HEXIM1 and HEXIM2 are differentially expressed. Expressed in endocrine tissues.
