The BaculoDirect™ Baculovirus Expression System is a powerful and versatile eukaryotic system for high-level protein expression in insect cells. The combination of Gateway™ Technology with baculovirus expression makes the BaculoDirect System the fastest and easiest method for production of recombinant baculovirus.

How it works
BaculoDirect™ Linear DNA (the baculovirus genome) is engineered to include attR sites for quick and efficient recombination with a Gateway entry clone. The gene of interest is recombined from the entry clone into the BaculoDirect Linear DNA using a simple, one-hour LR reaction (Figure 1). The resulting reaction mix contains the recombinant baculovirus carrying the gene of interest and is used to transfect insect cells. The need for transforming bacteria and isolating a large bacmid or co-transfecting a transfer vector and linear baculovirus DNA into insect cells is eliminated. As a result, the hands-on time is greatly reduced. Purified baculovirus can be isolated in less than one week.

Gateway linear DNA
BaculoDirect Linear DNA is designed for rapid cloning with a Gateway entry clone and subsequent expression in Sf9 or Sf21 insect cells. The Linear DNA features:

• Strong polyhedrin promoter for high-level expression
• R-sites for efficient recombination with any attL-flanked Gateway entry vector
• TK gene for negative selection using ganciclovir
• C-terminal V5-His tag (BaculoDirect™ C-Term Expression Kit) or N-terminal V5-His tag (BaculoDirect™ N-Term Expression Kit) for detection with anti-V5 antibody and purification with nickel-chelating resin
• TEV protease cleavage site for removal of the V5-His tag following purification (BaculoDirect N-Term Expression Kit)
• LacZ gene, to ensure a pure baculovirus stock is generated, which is replaced by your gene of interest after LR recombinant reaction

Additional materials required, available separately: Gateway entry clone.

자주 묻는 질문(FAQ)

I cannot grow this white colony in liquid culture. What should I do?

The concentration of gentamicin might be too high. Try lowering the amount to 5 µg/mL and try adding more of the colony to the culture medium.

What has happened when I see blue colonies? How about colonies which are blue in the center and white on the edges?

In the case of a blue colony, the E. coli has the bacmid and the plasmid in it, allowing the cells to survive the selection process. However, because the transposition has not occurred, the LacZ gene is not disrupted. For bulls-eye colonies, this indicates that the transposition took place when the colony was growing. Re-streaking for an isolated clone from the white portion of the mixed colony should yield some colonies where transposition occurred.

I'm getting mostly white/wild-type plaques instead of blue/recombinant plaques. What am I doing wrong?

This is typically an indication of poor homologous recombination. Check the plasmid/linear DNA ratio you used. If there are some blue plaques, however, expand those viruses and check for their protein. In our experience, they are correct, even if they were in relatively low abundance.

I've infected my cells and see large polyhedra in one cell and smaller polyhedra (more numerous) in a neighboring cell. Is this normal?

Yes, cells are infected with wild-type virus individually and will develop polyhedra at different rates until all the cells in the flask are infected. The polyhedra in cells will form in approximately 3-4 days, differing in size and number until they reach their maximum capacity and burst the cell, releasing tiny particles of virus into the medium.

I'm worried that I am not getting plaques. How many days does it take to see plaques and what size are they typically?

Normally, very small white dots show up about 5-7 days and 1 mm plaques show up around day 10. Plaques can vary in size from 1 mm to 4 mm.

Abstract

Functional characterization of five novel CYP2C8 variants, G171S, R186X, R186G, K247R, and K383N, found in a Japanese population.

Cytochrome P450 2C8 is one of the primary enzymes responsible for the metabolism of a wide range of drugs such as paclitaxel, cerivastatin, and amiodarone. We have sequenced the CYP2C8 gene from 201 Japanese subjects and found five novel nonsynonymous single nucleotide polymorphisms (SNPs): 511G>A (G171S), 556C>T (R186X; X represents the translational stop ...

Analysis of the large inactive P-TEFb complex indicates that it contains one 7SK molecule, a dimer of HEXIM1 or HEXIM2, and two P-TEFb molecules containing Cdk9 phosphorylated at threonine 186.

'Positive transcription elongation factor b (P-TEFb) regulates eukaryotic gene expression at the level of elongation, and is itself controlled by the reversible association of 7SK RNA and an RNA binding protein, HEXIM1 or HEXIM2.

'In eukaryotes, prereplication complexes (pre-RCs) containing ORC, Cdc6, Cdt1, and MCM2-7 are assembled on chromatin in the G1 phase. In S phase, when DNA replication initiates, pre-RCs are disassembled, and new pre-RC assembly is restricted until the following G1 period. As a result, DNA replication is limited to a single ...
