    Abstract: An integration-defective retroviral vector transfer cassette lacking a functional polypurine tract (PPT) is provided. Also provided are isolated nucleic acids that include a heterologous nucleotide sequence, one or two retroviral long terminal repeats (LTRs), a packaging signal, a rev responsive element, and a eukaryotic promoter, wherein the nucleic acid lacks a functional PPT; vectors that include the disclosed isolated nucleic acids; recombinant retroviral particles and mRNAs thereof; retroviral vector kits; and methods for producing integration-defective vector particles, achieving gene expression of a nucleotide sequence of interest, and inserting a nucleotide sequence of interest into a host cell genome in a site-specific or non-specific manner.

    Abstract: Recombinant expression vectors are provided comprising a 3' UTR of a light chain and an Epstein-Barr virus origin of replication. Also provided are host cells comprising such vectors and methods of producing recombinant protein with such vectors. Additional methods of producing a recombinant protein involve contacting cells with a first and second vector, each of which encode a different polypeptide chain, and wherein the second vector is present in an amount which is about 1.5 to 2.5 times as much as that of the first vector. Cells also can be transfected with a recombinant transient expression vector encoding a protein and are cultured in a medium in a membrane-enhanced culturing vessel to produce recombinant protein.

    Abstract translation: 提供重组表达载体,其包含轻链的3'UTR和Epstein-Barr病毒复制起点。 还提供了包含这种载体的宿主细胞和用这种载体产生重组蛋白的方法。 生产重组蛋白质的其它方法包括使细胞与第一和第二载体接触,第一和第二载体各自编码不同的多肽链,其中第二载体的存在量为第一载体的约1.5至2.5倍 向量。 细胞也可以用编码蛋白质的重组瞬时表达载体转染,并在膜增强培养容器中的培养基中培养以产生重组蛋白。
