SKU:: 123045
Purity:: Purified by Protein A affinity chromatography.
Storage Conditions:: -20°C
Supplier:: United States Biological
Host:: Mouse
Immunogen:: Partial recombinant corresponding to aa1-109 from human AFF4 (NP_055238) with GST tag. MW of the GST tag alone is 26kD.
Clone:: 2E12
Format:: Supplied as a liquid in PBS, pH 7.2.
Extra Details:: Key component of the super elongation complex (SEC), a complex required to increase the catalytic rate of RNA polymerase II transcription by suppressing transient pausing by the polymerase at multiple sites along the DNA. In the SEC complex, AFF4 acts as a central scaffold that recruits other factors through direct interactions with ELL proteins (ELL, ELL2 or ELL3) and the P-TEFb complex. In case of infection by HIV-1 virus, the SEC complex is recruited by the viral Tat protein to stimulate viral gene expression. Applications: Suitable for use in ELISA, Western Blot and Immunohistochemistry. Other applications not tested. Recommended Dilution: Immunohistochemistry (Formalin fixed paraffin embedded): 1ug/ml Optimal dilutions to be determined by the researcher.
