Dear Sir,

Molecular cloning is the advanced biomedical technology at present. The technique can be very helpful in tropical medicine. It can serve several purposes such as the finding for drug resistance gene,[1] finding for epitope,[2] and the construction of gene expression vector. Here, the author proposes for an example of successful performing on cloning of new third generation lentiviral gene expression vector. The VectorBuilder technique was used and the derived vector is, namely, “plentivirus (LV) Expression [Exp]-Neo-cytomegalovirus (CMV) > enhanced green fluorescent protein (EGFP)” [Figure 1], size 8828 bp. This is a lentiviral gene expression vector (third generation). The inserted promoter is “CMV”, inserted open reading frame (ORF) is “EGFP” and inserted marker is “Neo”. The sequence of the derived vector is shown in [Figure 2]. Further, restriction analysis, using primers as M13 (−48) reverse primer 8729-8752 and T7 primer 5971-5989 showed the result as in [Figure 3]. Of interest, the new cloned lentiviral gene expression vector has a CMV promoter, which is previously reported for possible usefulness in human immunodeficiency virus (HIV) medicine.[3] The application of the new derived vector has to be further studied.{Figure 1}{Figure 2}{Figure 3}
