background: trastuzumab (herceptin) is a humanized monoclonal antibody (mab) which is used for specific treatment of metastatic breast cancer in patients with overexpression of her2/neu receptor. in this study, we have attempted to develop a biosimilar version of trastuzumab mab. methods: according to in silico studies, the heavy and light chains of trastuzumab mab were designed and constructed...
A 13,863-base-pair (bp) putative centromeric DNA fragment has been isolated from a human genomic library by using a probe obtained from metaphase chromosomes of human colon carcinoma cells. The abundance of this DNA was estimated to be 16-32 copies per genome. Cotransfection of mouse cells with this sequence and a selectable marker gene (aminoglycoside 3'-phosphotransferase type II, APH-II) res...
We adapted a fusion polymerase chain reaction (PCR) strategy to synthesize gene disruption alleles of any sequenced yeast gene of interest. The first step of the construction is to amplify sequences flanking the reading frame we want to disrupt and to amplify the selectable marker sequence. Then we fuse the upstream fragment to the marker sequence by fusion PCR, isolate this product and fuse it...
Genetically-modified mutants are now indispensable Plasmodium gene-function reagents, which are also being pursued as genetically attenuated parasite vaccines. Currently, the generation of transgenic malaria-parasites requires the use of drug-resistance markers. Here we present the development of an FRT/FLP-recombinase system that enables the generation of transgenic parasites free of resistanc...
