Production And Purification Of Basic Fibroblast Growth Factor Fused To Two Collagen Binding Domains Expressed In E. Coli Bl21 Using Flask And Fed-Batch, Hazim Aljewari
Graduate Theses and Dissertations
Delivering effective and non-toxic doses of bioactive materials that can aid in activating tissue regeneration to wounded tissue has proven to be an enormous challenge. This study was designed to produce a potential therapeutic recombinant protein by fusing two collagen binding domains to basic fibroblast growth factors (bFGF) through a collagenase cleavage site linker, so it can release the bFGF in a wound site by the action of this enzyme. The novel fusion protein was expressed in Escherichia coli BL-21 (E. coli) using traditional flask shaker and fed-batch cultivation. Cell lysate was purified by FPLC using Immobilized metal affinity chromatography …
Assessment Of The Biocompatibilty, Stability, And Suitability Of Natural And Synthetic Polymers And Drugs In The Fda Approval Process, Phuong Anh Hoang Nguyen
Assessment Of The Biocompatibilty, Stability, And Suitability Of Natural And Synthetic Polymers And Drugs In The Fda Approval Process, Phuong Anh Hoang Nguyen
Biomedical Engineering ETDs
Regulation of the development, production, marketing, and sales of medical pharmaceuticals and devices in the United States fall under the regulatory functions of the Food and Drug Administration (FDA). The current FDA approval process takes an average of 10 years from start to completion, and costs over $100 million. As a result, companies use many different methods to find additional use of their drugs through marketing directly to the physician, or recycling of previously approved drug moieties. In this work, an evaluation of the in vitro and ex vivo biocompatibility of polymers and drugs in different phases of FDA approval …
Development Of In Situ Forming Hydrogels For Intra-Articular Drug Delivery, Andy Prince
Development Of In Situ Forming Hydrogels For Intra-Articular Drug Delivery, Andy Prince
Electronic Thesis and Dissertation Repository
Hydrogels are 3-dimensional crosslinked polymer networks that can absorb significant amounts of water. The physical properties associated with hydrogels affords them resemblance to biological tissues making them good candidates for biomedical applications. Many pharmaceuticals, specifically non-steroidal anti-inflammatory drugs (NSAIDs), have poor aqueous solubility, which limits their bioavailability and efficacy. People suffering from chronic osteoarthritis (OA) are required to frequently take large doses to mitigate pain, which can lead to serious side effects. Hydrogels are good strategies to deliver NSAIDs via articular injection because they can form solid gels in situ. This thesis describes the synthesis, formulation, mechanical testing, in …
