Reproducibility is key to advancing scientific discovery and accelerating scientists’ next breakthrough.
Abcam is leading the way with our range of recombinant antibodies, knockout-validated antibodies and knockout cell lines, all of which support improved reproducibility.
We are also planning to innovate the way in which we present recommended applications and species on our product datasheets, so that only applications & species that have been tested in our own labs, our suppliers or by selected trusted collaborators are covered by our Abpromise™ guarantee.
In preparation for this, we have started to update the applications & species that this product is Abpromise guaranteed for.
We are also updating the applications & species that this product has been “predicted to work with,” however this information is not covered by our Abpromise guarantee.
Applications & species from publications and Abreviews that have not been tested in our own labs or in those of our suppliers are not covered by the Abpromise guarantee.
Please check that this product meets your needs before purchasing. If you have any questions, special requirements or concerns, please send us an inquiry and/or contact our Support team ahead of purchase.

Function: This protein is a positive regulator for the gene expression of the galactose-induced genes such as GAL1, GAL2, GAL7, GAL10, and MEL1 which encode for the enzymes used to convert galactose to glucose. It recognizes a 17 base pair sequence in (5'-CGGRNNRCYNYNCNCCG-3') the upstream activating sequence (UAS-G) of these genes. Subunit structure: Binds DNA as a homodimer. Interacts directly with the mediator subunits GAL11/MED15 and SRB4/MED17. Domain: The 9aaTAD motif (residues 862 to 870) is a transactivation domain present in a large number of yeast and animal transcription factors. Post-translational modification: Association between GAL11 and GAL4 may serve to expedite phosphorylation of GAL4. -

ChIP - Anti-GAL4 antibody (ab1396)This image is courtesy of the Tony Kouzarides lab at the Gurdon Institute.A stably transfected 293T human cell line harbouring the GAL4 upstream activation sequence was transiently transfected with a V5 or T7- tagged GAL4 DNA Binding Domain construct. 48 hours post transfection Chromatin was prepared according to the Abcam X-ChIP protocol. The ChIP was performed with 25 ug chromatin, 5ug of antibody and 20 ul of Protein A/G beads. A non-specific antibody was used as the negative control. The immunoprecipitated DNA was quantified by real time PCR (SYBR Green approach). -
ChIP - Anti-GAL4 antibody (ab1396)This image is courtesy of an anonymous collaborator.S. cerevisiae cells were incubated in raffinose-containing media then transferred to galactose-containing media to activate transcription of galactose activated genes. IP was performed with 500µl of cell extract incubated overnight with 5µl of ab1396 at 4°C, followed by the addition of 25µl of protein A sepharose beads and incubation for 2 hours (room temp). The subsequently purified DNA was analysed with 3 pairs of primers (see diagram). The results show that Gal4 binds specifically to the UAS region of Gal1-Gal10 in both raffinose and galactose, despite only 500-600bp between the UAS and 5' primer.
