pAcVE1 Transfer Vector Instructions
Description
ParaTechs’ pAcVE1 baculovirus transfer vector is designed for high level expression of foreign genes under the control of the Autographa californica nuclear polyhedrosis virus (AcMNPV) polyhedrin promoter. Increased recombinant protein production over conventional baculovirus transfer vectors is achieved by allowing co-expression of foreign genes with a vankyrin expression cassette (Fath-Goodin et al., 2006). pAcVE1 is derived from the pUC57 vector. Foreign genes may be cloned into the multiple cloning site utilizing the following restriction sites: AvrII; SbfI; XhoI; BglII; EagI; NotI; NheI. pAcVE1 baculovirus transfer vector is a polyhedrin locus-based transfer vector that is compatible with any baculovirus system that utilizes homologous recombination in insect cells, including flashBac (Oxford Expression Technologies) and Bac-N-Blue (Invitrogen).
Contents
The plasmid DNA was prepared on a silicon bead matrix and dissolved in TE buffer (10mM Tris-HCl, pH7.5; 1 mM EDTA). pAcVE1 baculovirus transfer vector is provided at 10 µg in 20 µl.
Storage
Transfer vector should be placed at -20°C for long- term storage.
Handling
For expression of recombinant protein under the polyhedrin promoter, the gene of interest should be ligated into an appropriate restriction site in the multiple cloning site of the pAcVE1 vector (see below). Transform the recombinant pAcVE1 transfer vector in E. coli cells (Top10 or any other suitable strain), propagate the cells under ampicillin selection and purify the recombinant plasmid using standard plasmid purification protocols. For construction of recombinant AcMNPV virus perform a co-transfection of the purified recombinant pAcVE1 vector with linearized baculovirus DNA suitable for homologous recombination in insect cells.

pAcVE.02 Transfer Vector Instructions
Description
pAcVE.02 is a Vankyrin-Enhanced (VE) baculovirus transfer vector designed for high levels of recombinant gene expression under the control of the Autographa californica nucleopolyhedro virus (AcMNPV) polyhedrin promoter. pAcVE.02 is derived from pUC57 and contains the pUC origin of replication and the ampicillin resistance gene for propagation and selection in bacteria. pAcVE.02 is designed for the direct secretion of recombinant proteins utilizing the honeybee melittin signal sequence (Tessier et al., 1991). An N-terminal 8xHis-tag is provided for ease of purification. Cloning into pAcVE.02 requires the DNA insert to be in frame with the N-terminal 8xHis tag. Foreign genes may be cloned into the multiple cloning site utilizing the following restriction sites: NotI; SbfI and NheI. PmeI can be used if a C-terminal 8xHis-tag instead of the N-terminal His-tag is required or if the His-tag is not desired. Increased recombinant protein production over conventional baculovirus transfer vectors is achieved by the co-expression of the gene of interest with a vankyrin expression cassette (Fath-Goodin et al., 2006). pAcVE.02 contains ORF 603 and ORF1629 sequences and allows recombination with the viral DNA for insertion into the polyhedrin locus. The baculovirus transfer vector is compatible with any baculovirus system that utilizes homologous recombination in insect cells, including flashBAC (Oxford Expression Technologies) and Bac-N-Blue (Invitrogen).
Contents
The plasmid DNA is dissolved in TE buffer (10mM Tris-HCl, 1 mM EDTA pH7.5). pAcVE.02 baculovirus transfer vector is provided at 10µg in 50µl.
Storage
The transfer vector should be placed at -20º C for long-term storage.
Handling
For expression of recombinant protein under the polyhedrin promoter, the gene of interest should be ligated into an appropriate restriction site in the multiple cloning site of the pAcVE.02 vector and should be in frame with the N-terminal His-tag (see diagram). Transform the recombinant pAcVE.02 transfer vector in E. coli cells (DH5α, Top10 or any other suitable strain), propagate the cells under ampicillin selection and purify the recombinant plasmid using standard plasmid purification protocols. For construction of recombinant AcMNPV perform a co-transfection of the purified recombinant pAcVE.02 vector with linearized baculovirus DNA suitable for homologous recombination in insect cells.

pAcVE.03 Transfer Vector Instructions
Description
pAcVE.03 is a Vankyrin-Enhanced (VE) baculovirus transfer vector designed for high levels of recombinant gene expression under the control of the Autographa californica nucleopolyhedro virus (AcMNPV) polyhedrin promoter. pAcVE.03 is derived from pUC57 and contains the pUC origin of replication and the ampicillin resistance gene for propagation and selection in bacteria. pAcVE.03 is designed for the direct secretion of recombinant proteins utilizing the honeybee melittin signal sequence (Tessier et al., 1991). An optional C-terminal 6xHis-tag is provided for ease of purification. Cloning into pAcVE.03 requires the DNA insert to be in frame with the honeybee melittin signal sequence. Foreign genes may be cloned into the multiple cloning site utilizing the following restriction sites: NcoI; SbfI; XhoI; BstZ17I; BglII; SacII and EagI. Increased recombinant protein production over conventional baculovirus transfer vectors is achieved by the co-expression of the gene of interest with a vankyrin expression cassette (Fath-Goodin et al., 2006). pAcVE.03 contains ORF 603 and ORF1629 sequences and allows recombination with the viral DNA for insertion into the polyhedrin locus.

Storage
The transfer vector should be placed at -20º C for long-term storage.
Handling
For expression of recombinant protein under the polyhedrin promoter, the gene of interest should be ligated into an appropriate restriction site in the multiple cloning site of the pAcVE.03 vector and should be in frame with the honey bee melittin signal sequence and the C-terminal 6xHis-tag if desired (see diagram and table). In that instance the stop codon needs to be omitted. Transform the recombinant pAcVE.03 transfer vector in E. coli cells (DH5α, Top10 or any other suitable strain), propagate the cells under ampicillin selection and purify the recombinant plasmid using standard plasmid purification protocols. For construction of recombinant AcMNPV perform a co-transfection of the purified recombinant pAcVE.03 vector with linearized baculovirus DNA suitable for homologous recombination in insect cells.
