pACP-tag(m)-2 Vector

Features

BACKGROUND:

A plasmid map and the sequence of the cloning region can be found above. The complete plasmid sequence can be downloaded. This plasmid encodes the gene ACPwt which is the wild type Acyl Carrier Protein from E. coli. In the plasmid sequence, the ACPwt gene is encoded from bp 975 to 1208. The ACPwt gene was cloned via EcoRI and SbfI including additional flanking restriction sites.

This plasmid is intended for the cloning and stable or transient expression of ACP-tag protein fusions in mammalian cells. It is suitable for the efficient production of stable cell lines expressing ACP-tag gene fusions. The plasmid contains the CMV promoter followed by the genes for the ACP-tag and neomycin resistance separated by the IRES of the encephalomyocarditis virus (ECMV), which permits the translation of two open reading frames from one messenger RNA; therefore after selection of stable mammalian cells for neomycin resistance, nearly all surviving colonies should stably express the ACP-tag fusion protein. Unless the expression experiments require a pure population of cells, the pool of resistant cells can simply be used, otherwise cell clones can be isolated and characterized using standard procedures.

The plasmid contains the β-lactamase (Ampicillin resistance) gene for maintenance in bacteria. The gene of interest should be cloned downstream of the ACP-tag coding sequence, as a fusion to the C-terminus of the ACP-tag. An appropriate cell surface signal peptide should be cloned upstream of the ACP-tag as an N-terminal fusion. A Kozak sequence is located upstream of the ACPwt gene to increase the translation efficiency of the fusion protein. The ACPwt gene can be isolated from the plasmid using PCR or direct cloning in order to subclone it into a different vector of choice.

1. Storage: pACP-tag(m)-2 is supplied in TE buffer (10 mM Tris-HCl, pH 8.0, 1 mM EDTA) at a concentration of 0.5 µg/µl. Plasmid solutions can be stored at 4°C for up to one week. For long-term storage -20°C is recommended.
