CheckMate™/Flexi® Vector Mammalian Two-Hybrid System

The CheckMate™/Flexi® Vector Mammalian Two-Hybrid System provides a means to confirm, validate and study suspected interactions between two proteins or domains and can also be used to generate stable cell lines for cell-based assays. Developed primarily for mammalian proteins of interest, the system can allow protein expression and post-translational modifications in an environment mimicking the native cell milieu. It is patterned on the yeast two-hybrid system with one protein of interest ("X") fused to a DNA-binding domain and the other protein ("Y") fused to a transcriptional activation domain (Figure 1).
