λ Vectors for Stable Cloned Gene ExpressionBiotechnology Progress - Tập 6 Số 4 - Trang 277-282 - 1990
Nandan Padukone, S. Peretti, David F. Ollis
AbstractThe bacteriophage λ offers a unique opportunity concurrently to minimize segregational instability in recombinant systems by chromosomal integration of the cloned gene and to achieve high cloned gene expression during an abortive lytic phase. Lysis leads approximately to a 100‐fold amplification of the cloned gene. Cell lysis in the lytic state is blocked b...... hiện toàn bộ
Separation of Genomic DNA from Plasmid DNA by Selective Renaturation with Immobilized Metal Affinity CaptureBiotechnology Progress - Tập 21 Số 5 - Trang 1472-1477 - 2005
Tony Cano, Jason C. Murphy, George E. Fox, Richard C. Willson
AbstractIn contrast to proteins, many nucleic acids can undergo reversible modification of their conformations, and this flexibility can be used to facilitate purification. Selective renaturation with capture is a novel method of removing contaminating genomic DNA from plasmid samples. Plasmid DNA quickly renatures after thermal denaturation and cooling (or alkalin...... hiện toàn bộ
Loofa Sponge as a Scaffold for the Culture of Human Hepatocyte Cell LineBiotechnology Progress - Tập 19 Số 2 - Trang 522-527 - 2003
Jyh‐Ping Chen, Sheng‐Chun Yu, Brend Ray‐Sea Hsu, Shin‐Huei Fu, Hwai‐Shen Liu
AbstractLoofa sponge was investigated as a three‐dimensional scaffold for stationary and perfusion culture of human hepatoblastoma cell line C3A/HepG2. In stationary culture, C3A/HepG2 cells in loofa cubes showed higher α‐fetoprotein and albumin secretion rates than those in polyurethane foam (PU). To use loofa cylinders in a packed‐bed reactor, immobilization of C...... hiện toàn bộ
A Computer Model Based on Reaction‐Diffusion Equations for the Growth of Filamentous Fungi on Solid SubstrateBiotechnology Progress - Tập 9 Số 4 - Trang 385-393 - 1993
Paul Molin, Patrick Gervais, Jean‐Pierre Lemiere
AbstractA model of two reaction‐diffusion equations for biomass production and glucose consumption was developed. Experiments were carried out in order to estimate the different constants of the model and to compare the behavior of the system using two species of fungi, Rhizopus oligosporus and Trichoderma viride T.S.... hiện toàn bộ
Current Perspectives on Stability of Protein Drug Products during Formulation, Fill and Finish OperationsBiotechnology Progress - Tập 24 Số 3 - Trang 504-514 - 2008
Nitin Rathore, Rahul S. Rajan
AbstractCommercialization of protein‐based therapeutics is a challenging task in part due to the difficulties in maintaining protein solutions safe and efficacious throughout the drug product development process, storage, transportation and patient administration. Bulk drug substance goes through a series of formulation, fill and finish operations to provide the fi...... hiện toàn bộ
