Term
Advantage of Recombinant products |
|
Definition
natural product sources may be limited; typically cheaper; avoids immunogenicity; avoids pathogen contamination; highly specific recognition and affinity |
|
|
Term
disadvantages of recombinant products |
|
Definition
may not have a good half life; more complex production, can be fragile; tend to aggregate to protease in vivo making them ineffective |
|

Advantages of production in E. Coli |
|
Definition
Well characterized host; rapid growth and ability to produce large amounts of foreign proteins; ease of handling; fermentation well established; no transfer of pathogens |
|
|
Term
Challenge of production in E. Coli |
|
Definition
Most products are made as inclusion bodies; does not glycosylate so production is limited to proteins that do not require this process; other post-translational processes do not occur the same way as in eukaryotic cells |
|
|
Term
advantages of production in yeast (S. cerevisaiae) |
|
Definition
can perform some post-translational modifications like glycosylation; short generation time and easily cultured; can be transformed allowing for addition of new genes or deletion through homologous recombination |
|
|
Term
|
Definition
glycosylation between yeast and mammalian cells is quite different and produces different products; humanized yeast are being developed to overcome this problem |
