(author), TNO Kwaliteit van Leven (author)To study the influence of the carbohydrate-moiety of ovalbumin on the formation of the heat-stable conformer S-ovalbumin, ovalbumin is deglycosylated with PNGase-F under native conditions. Although the enzymatic deglycosylation procedure resulted in a complete loss of the ability to bind to Concavalin A column-material, only in about 50% the...article 2007

(author), TNO Kwaliteit van Leven (author)Background: During wound repair, fibrin acts both as a barrier to prevent blood loss and as a temporary matrix for the invasion and ingrowth of endothelial and tissue cells. A well-controlled angiogenesis process in the fibrinous exudate matrix is crucial for optimal wound healing. The composition and structure of the fibrin matrix are important...article 2006

In the case of a targeted approach, potential bottlenecks, feed-back inhibition, and side-routes are removed, and other processes of interest are targeted by overexpressing or knocking-out the gene(s) of interest. To date, the selection of...article 2005
