pCI Mammalian Expression Vector<br />

Product Size Cat.# Price ($)<br />

pCI Mammalian Expression Vector 20 µg E1731 423.00<br />

For Research Use Only. Not for Use in Diagnostic Procedures.<br />

Description: The pCI Mammalian Expression Vector promotes constitutive<br />

expression of cloned DNA inserts in mammalian cells. The major difference<br />

between the pCI and pSI Mammalian Expression Vectors is the enhancer/<br />

promoter region controlling the expression of the inserted gene. The<br />

pCI Expression Vector contains the human cytomegalovirus (CMV) major<br />

immediate-early gene enhancer/promoter region. This vector can be used for<br />

both transient and stable expression of genes. For stable expression, the pCI<br />

Vector must be co-transfected with an expression vector containing a<br />

selectable gene for mammalian cells.<br />

Features:<br />

• Strong, Constitutive Expression: The pCI Vector’s CMV enhancer/<br />

promoter region enables strong, constitutive expression in many cell types.<br />

A β-globin/IgG chimeric intron located downstream of the enhancer/<br />

promoter region can further increase expression.<br />

• Increased Steady-State mRNA Levels: The late SV40 polyadenylation<br />

signal increases the steady-state level of RNA approximately fivefold more<br />

than the early SV40 polyadenylation signal.<br />

• Convenient: Multiple cloning sites exist for easy insertion of cDNA.<br />

• Versatile: Synthesize transcripts in vitro using the T7 RNA polymerase<br />

promoter or generate single-stranded DNA in E. coli using the f1 origin of<br />

replication.<br />

Storage Conditions: Store at –20°C.<br />

pCI-neo Mammalian Expression Vector<br />

Product Size Cat.# Price ($)<br />

pCI-neo Mammalian Expression Vector<br />

For Research Use Only. Not for Use in Diagnostic Procedures.<br />

20 µg E1841 455.00<br />

Description: The pCI-neo Mammalian Expression Vector carries the human<br />

cytomegalovirus (CMV) immediate-early enhancer/promoter region to promote<br />

constitutive expression of cloned DNA inserts in mammalian cells. This vector<br />

also contains the neomycin phosphotransferase gene, a selectable marker<br />

for mammalian cells. The pCI-neo Vector can be used for transient or stable<br />

expression by selecting transfected cells with the antibiotic G-418.<br />

Features:<br />

• Strong, Constitutive Expression: The human cytomegalovirus (CMV)<br />

immediate-early enhancer/promoter region produces strong, constitutive<br />

expression. A β-globin/IgG chimeric intron located downstream from the<br />

enhancer/promoter region can further increase expression. The vector is<br />

maintained as an episome in cells expressing the SV40 large T antigen,<br />

leading to even higher levels of expression.<br />

• Transient or Stable Expression: The neomycin phosphotransferase<br />

gene allows selection of stable transfected cells.<br />

• Increased Steady-State mRNA Levels: The late SV40 polyadenylation<br />

signal increases the steady-state level of RNA approximately fivefold more<br />

than the early SV40 polyadenylation signal.<br />

• Convenient: Multiple cloning sites exist for easy insertion of cDNA.<br />

• Versatile: Synthesize transcripts in vitro using the T7 RNA polymerase<br />

promoter or generate single-stranded DNA in E. coli using the f1 origin of<br />

replication.<br />
