pXINSECT-DEST38載體優勢：
Using the Express Insect Kit or the Express Insect Vector Set to achieveprotein expression in insect cells has the following advantages:
 Non-lytic, continuous protein expression
 Minimal degradation of your protein of interest as compared to viralexpression systems
 Higher protein expression level achieved than other similar non-viral insectexpression systems
 Choice of transient or stable protein expression
 Adapted for use with the Gateway Technology or traditional restrictionenzyme-mediated cloning

載體特征：
pXINSECT-DEST38 and pXINSECT-DEST39 have the following features:
 The silkmoth (Bombyx mori) cytoplasmic actin gene promoter for constitutive expression of the gene of interest (Johnson et al., 1992)
 The viral transcriptional enhancer, homologous region 3 (HR3) from Bombyx mori nuclear polyhedrosis virus (BmNPV) acts as a constitutive enhancer of the cytoplasmic actin promoter (Lu et al., 1997)
 A viral transcriptional transactivator, BmNPV IE1, to stimulate expression of your gene of interest (Lu et al., 1996)
 N-terminal 6xHis tag fusion proteins to facilitate detection and purification of your protein of interest using pXINSECT-DEST39
 Two recombination sites, attR1 and attR2, for recombinational cloning of the gene of interest from an entry clone
 Chloramphenicol resistance gene located between the two attR sites for counterselection
 The ccdB gene located between the two attR sites for negative selection
 The actin polyadenylation signal for efficient transcription termination and polyadenylation of mRNA
 Ampicillin resistance gene for selection of transformants in E. coli
 The pUC origin for high copy replication and maintenance of the plasmid in E. coli
