Seed train optimization for suspension cell culture

Introduction The purpose of a seed train is the generation of an adequate number of cells for the inoculation of a production bioreactor. This is timeand cost-intensive: From volumes used for cell thawing or cell line maintenance the cell number has to be increased. The cells are usually run through many cultivation systems which become larger with each passage (e.g. T-flasks, roller bottles or...

Cell Suspension Culture, Somatic Embryo Genetic and Synthetic Seed Production in Different Cultivars of Potato

Extended Abstract Introduction and Objective: In order to overcome the contamination problems, as well as the usual method of increasing potato through micro tuber, micropropagation has been considered through tissue culture. The aim of this study was to evaluate the callus induction and embryogenesis in potato cultivars using leaf explants. Material and Methods: For this purpose, micropropa...

Model-based design of the first steps of a seed train for cell culture processes

Concept Production of biopharmaceuticals for diagnostic and therapeutic applications with suspension cells in bioreactors requires a seed train up to production scale [1]. For the final process steps in pilot and production scale the scale-up steps are usually defined (e.g. a factor of 5 10). More difficult in this respect are the first steps, the transitions between T-flasks, spinner tubes, ro...

Model-based strategy for cell culture seed train layout verified at lab scale.

Cell culture seed trains-the generation of a sufficient viable cell number for the inoculation of the production scale bioreactor, starting from incubator scale-are time- and cost-intensive. Accordingly, a seed train offers potential for optimization regarding its layout and the corresponding proceedings. A tool has been developed to determine the optimal points in time for cell passaging from ...

application of suspension cell culture for preparation of viral antigens

introduction: hela cell is a widely studied cell line derived from human cerzix adenocarcinoma. the cells are epithelial - like in morphology and susceptible to polio viruses and adenovirus type 5. hela cells are usually as monolayer for isolation and propagation of some human viruses, as well as for the expression of recombinant proteins, including hepatitis b surface antigen. the aim of this ...
