Two-hybrid systems are extremely powerful methods for detecting protein:protein interactions in vivo. The basis of two-hybrid systems is the modular domains found in some transcription factors: a DNA-binding domain, which binds to a specific DNA sequence, and a transcriptional activation domain, which interacts with the basal transcriptional machinery. A transcriptional activation domain in association with a DNA-binding domain will promote the assembly of RNA polymerase II complexes at the TATA box and increase transcription. In the CheckMate Mammalian Two-Hybrid System the DNA-binding domain and the transcriptional activation domain, produced by separate plasmids, are closely associated when one protein (X) fused to a DNA-binding domain interacts with a second protein (Y) fused to a transcriptional activation domain. In this system, interaction between proteins X and Y results in transcription of a reporter gene.|
Mammalian System: Interactions can be studied in the cell line of choice. Proteins are more likely to be in their native conformation. Post-translational modifications, such as glycosylation, phosphorylation and acylation, are better maintained. Convenient Quantitation: The Dual-Luciferase(R) Reporter Assay System is used for detection.Internal Control: Renilla luciferase normalizes transfection efficiency. Fast Transient Assay: Results obtained two days after transfection, as compared to 3-4 days with the yeast system. Stable Transfectants: The pACT Vector contains the neomycin phosphotransferase gene, which allows for selection of stable transfectants.

If the researcher is not willing to accept the conditions of this limited use statement, and the product is unused, Promega will accept return of the unused product and provide the researcher with a full refund.Researchers may use this product for research use only, no commercial use is allowed. Commercial Use means any and all uses of this product and derivatives by a party for monetary or other consideration and may include but is not limited to use in: (1) product manufacture; and (2) to provide a service, information or data; and/or resale of the product or its derivatives, whether or not such product or derivatives are resold for use in research. Researchers shall have no right to modify or otherwise create variations of the nucleotide sequence of the luciferase gene except that Researchers may: (1) create fused gene sequences provided that the coding sequence of the resulting luciferase gene has no more than four deoxynucleotides missing at the affected terminus compared to the intact luciferase gene sequence, and (2) insert and remove nucleic acid sequences in splicing research predicated on the inactivation or reconstitution of the luminescence of the encoded luciferase. No other use or transfer of this product or derivatives is authorized without the prior express written consent of Promega. In addition, Researchers must either: (1) use luminescent assay reagents purchased from Promega Corporation for all determinations of luminescence activity of this product and its derivatives; or (2) contact Promega to obtain a license for use of the product and its derivatives.
