The goal of upstream biomanufacturing is to grow cells that will produce a desired protein, the protein being further purified during the downstream processing steps (see Downstream Processing chapter).
Upstream processing of proteins using bioreactors and cells usually begins with the preparation of the inoculum which proceeds in scale-up steps until enough inoculum is made to aseptically inoculate the final, sterile, media-filled bioreactor.
Nov 24, 2021 · Upstream processing is the first part of the biopharmaceutical production process. At this stage engineered cell lines, either microbial or mammalian, are utilized for efficient scalable production of the specific target protein or API.
Downstream processing refers to the recovery and purification of biosynthetic products, particularly pharmaceuticals from natural sources such as animal or plant tissue or fermentation both including the recycling of salvageable components and the proper treatment and the disposal of waste.
Upstream processing involves all the steps related to inoculum development, media development, improvement of inoculum by genetic engineering process, optimization of growth kinetics so that product development can improve tremendously. Fermentation has two parts: upstream and downstream.
What is upstream processing? Upstream processing is the first stage in producing biopharmaceuticals, such as cell or microbial cultures, to produce the therapeutic protein. This process involves a series of steps to achieve the desired outcome.
Jan 1, 2018 · Developing a robust, high-yielding upstream process is a complex and challenging task, and a good result is a combination of powerful technology, high-quality starting materials, and clever process design.
What is upstream processing? Upstream processing is the technique of developing and culturing a cell line to expand the culture in volume until final harvest.
Upstream process is the first step of bioprocess from early cell isolation and cultivation, to cell banking and culture development of the cells until final harvest where the desired quantity is reached.
Nov 2, 2022 · For upstream processing, the cell line dictates the mode in which we run the upstream process. Thus, having the right producer cell for our lentiviral process can really make or break process performance—and, by extension, our ability to intensify the process to commercially-relevant scale.
