Article Synopsis
  • Hemolysis is a rare but serious risk linked to IVIG therapy due to antibodies to blood groups A and B, and an immunoaffinity chromatography (IAC) step can potentially lower these antibodies.
  • Objectives included comparing isoagglutinin levels in IVIG produced with and without IAC and determining if IAC could be scaled for industrial production.
  • Results showed that IAC significantly reduced isoagglutinin levels in IVIG while maintaining overall product quality, confirming its effectiveness and feasibility for large-scale manufacturing.

Background: Cyclosporin A (CsA) has been shown to be highly effective in the therapy of atopic dermatitis (AD). However, little information exists on the treatment of AD patients with Sandimmun Neoral(R) (Neoral), a microemulsion of CsA with improved pharmacokinetic properties in comparison to Sandimmun(R).

Objective: We have compared the efficacy and tolerability of Sandimmun and Neoral.

Endo-beta-glucanase I (EGI) of Trichoderma reesei was produced in laboratory and pilot scale using recombinant strains of "bottom-fermenting" Saccharomyces cerevisiae. The gene eg/1 was integrated in the chromosome or an expression cassette was inserted on a multicopy plasmid. Expression levels were compared in a laboratory scale bioreactor.

Cellobiohydrolase II of Trichoderma reesei was produced in laboratory and pilot scale using a transformant strain of Saccharomyces cerevisiae harbouring a multicopy expression plasmid. Different strategies were compared for concentration and partial purification of the enzyme produced in a 200 1 pilot cultivation. After efficient separation of biomass and sub-cellular particulate matter, a combination of ultrafiltration and adsorbent treatment for removal of protein impurities was used to provide a concentrate for chromatographic purification.
