|Background||The GAL4 protein of Saccharomyces cerevisiae is one of the most thoroughly characterized transcriptional activators. Since the N-terminal 147 amino acid residues of GAL4 are sufficient to mediate specific and strong binding to DNA, but are incapable of efficient transcriptional activation , this protein fragment has frequently been used to confer specific DNA binding in experiments examining transcriptional activation functions of heterologous proteins. This approach is facilitated by the finding that higher eukaryotes lack endogenous proteins that enhance transcription from the consensus GAL4-binding site. Fusions between GAL4 (aa 1-147) and activating domains from a variety of transcriptional regulatory proteins can activate transcription in yeast, plant, insects and mammalian cells. A unique "two-hybrid" system has been developed using GAL4 fusions in yeast to identify specific protein-protein interactions.|
|Others||The antibody detects endogenous GAL4 DNA Binding Domain protein.|

1.The species of antibody reactivity should be the sample species that can be matched normally after Abbkine R&D experts have passed strict scientific verification. If your sample is not within the range of reactivity, in order to improve the efficiency and results of your experiment, it is not suggested to try other species. Otherwise, it may lead to sample mismatch and affect the effect of your experiment.
2.Please aliquot the antibody received as soon as possible and store it at -20℃, avoid repeated freezing and thawing, and use it within one year.
