pCMV-Gaussia-Dura Luc 载体简介 The Thermo Scientific pCMV-Gaussia-Dura Luc vector is a derivative of pMCS-Gaussia-Dura Luc. It contains a mutant form of the Gaussia luciferase gene (conferring better bioluminescent signal stability than the native luciferase) under the control of the strong Cytomegalovirus (CMV) promoter. This constitutive expression vector can be used as a normalization control to account for experimental variation in combination with other reporters.
载体特征:
Strong (CMV) constitutive promoter for co-transfection and normalization
Naturally-secreting Gaussia-Dura luciferase gene, optimized for high expression and glow-stability in mammalian systems
Multiple cloning site (MCS) provides versatility for transfer of regulatory elements from one plasmid to another
Transcription termination site (Ter), Lac operator (Lac O1), and transcriptional pause site (TPS) used to minimize background by reducing transcriptional read-through
Both puromycin (Pur) and ampicillin (Amp) markers for drug selection in mammalian and bacterial cells, respectively
High-copy pUC bacterial DNA replication origin
Gaussia-Dura luciferase (approx. 20kDa) is a secreted protein that enables measurement of the reporter activity in media (for real-time assays) and in cell lysates. The parent pMCS vector contains a multiple cloning site for cloning a promoter to study its regulatory potential.
