DNA vector construction is a fundamental technique in molecular biology that involves creating recombinant DNA molecules for various applications. It plays a crucial role in genetic engineering, gene therapy, and biotechnology research. By designing and assembling DNA sequences into a vector, which acts as a carrier, DNA vector construction enables the delivery of desired genetic material into target cells or organisms. This process is essential for manipulating and studying genes, as well as for developing new treatments and therapies.
Our DNA vector construction service follows a well-defined process to ensure the successful delivery of high-quality vectors. Here is an overview of the steps involved:

First generation DNA vaccine vectors such as pVAX1 ( Figure 1b) and gWIZ ( Figure 1a) contain the kanamycin resistance (kanR) gene as a selectable marker. pVAX1 is a basic vector that contains no eukaryotic or bacterial region optimizations, and consequently has relatively low manufacturing yield and expression in vitro and in vivo (mice) [21]. pVAX1 expression is reduced, compared to alternative CMV promoter vectors, by inhibitory sequences in the bacterial region (see Section 5.1). The pUC origin is oriented such that the pUC origin encoded cryptic eukaryotic promoter [19] will transcribe RNA antisense to the transgene (Figure 1b); this may produce dsRNA and reduce expression by RNA interference or PKR mediated translational inhibition. The gWIZ vector has 5-fold improved expression and 2-fold increased manufacturing yields relative to pVAX1 [21] due to extensive optimization of the orientation and composition of the bacterial region [17] and addition of an intron upstream of the transgene.

(a,b) 1st; (c) 2nd; and (d) 3rd; generation DNA Vaccine vectors; (e) 2nd and 3rd generation vectors increase in vivo expression compared to first generation vector gWIZ. 5 µg muSEAP vectors delivered intramuscularly with EP to mice on day 0, serum muSEAP assayed on indicated days. 3rd generation vector NTC9385R has significantly higher expression than gWIZ or 2nd generation vector NTC8385 (p-value = 0.05; Mann-Whitney rank-sum test); (f) 3rd generation vectors dramatically increase in vivo expression, compared to 2nd generation. 50 µg muSEAP vectors in 50 µL saline delivered intradermally to mice with EP on day 0, muSEAP assayed on indicated days. 3rd generation vector NTC9385R has significantly higher expression than 2nd generation vector NTC8685 (p-value = 0.05; Mann-Whitney rank-sum test). NTC8685 is a 2nd generation vector similar to NTC8385. The NTC8385 1,518 basepair (bp) bacterial region (spacer region) is reduced to 855 bp in NTC8385-min and 454 bp in NTC9385R. This compares to 2,678 bp for gWIZ, and 1,970 bp for pVAX1. Figu
