Red Firefly Luc vectors contains a mutant form of the firefly luciferase gene that has a red-shifted emission spectrum.

• Intracellular Red Firefly luciferase gene, optimised for high expression 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 minimise 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

pMCS-Red Firefly Luc is a multiple cloning site plasmid designed to accept a promoter sequence for the study of gene regulation using the intracellular red firefly luciferase reporter with excellent light intensity.
pCMV-Red Firefly Luc is a constitutive expression vector having the luciferase gene under the CMV (Cytomegalovirus) promoter. Strong (CMV) constitutive promoters for co-transfection and normalisation.
pTK-Red Firefly Luc is a constitutive expression vector having the luciferase gene under the Herpes Simplex Virus (HSV) thymidine kinase (TK) promoter. Weak (TK) constitutive promoters for co-transfection and normalisation.
