BAC supplies ligands for use in large-scale manufacturing processes through specialist commercial partners, with a long lasting commitment of delivering high quality products for the purification of biopharmaceuticals. Ligands available as products which can be used for clinical production or manufacturing include ligands for the purification of:
- Human IgG – marketed by GEHC (GE Healthcare) as IgSelect
This product enables the purification of IgG1, IgG2, IgG3 and IgG4 from any source caused by its human specificity, making it extremely suitable for the purification of monoclonals from transgenic sources or IVIG from plasma. Besides this specificity the product can as well be used with caustic cleaning and has milder elution conditions than other products.
- Fab Kappa – marketed by GEHC as KappaSelect
This unique product enables the plug and play purification of any antibody format containing the kappa light chain, including antibody fragments, IgM, IgA and IgG’s in a single step process.
- Adeno-Associated Virus – marketed by GEHC as AVB sepharose HP
This product has been demonstrated to be able to purify AAV serotypes 1, 2, 3, 5, 8 in a single step process to a high degree of purity while retaining infectivity. This product eliminates the use of the poorly scalable multi-step process including density gradient centrifugation.
- Recombinant Factor VIII – marketed by GEHC as VIIISelect
A product developed for the purification of recombinant factor VIII. Companies interested in the purification of factor VIII from plasma can obtain samples from GEHC but should contact BAC for a license arrangement.
- Human Alpha-1 Antitrypsin (hAAT) - marketed by GEHC as Alpha-1 Antitrypsin Select
A product developed for the purification of human AAT from different sources such as, recombinant, plasma derived and transgenically produced AAT.
- Factor VII - marketed by GEHC as VIISelect
A product developed for the purification of both plasma derived as well as recombinantly produced human Factor VII / Factor VIIa
- Fab lambda - marketed by GEHC as LambdaFabSelect
This product is suitable for purification of any human antibody format containing a lambda light chain, including antibody fragments, IgM, IgA and IgG's in a single step process.
Alternative ligand designs can be developed through our Custom Ligand Design service.
Leakage assays for use as a tool to aid process development, or in routine quality control processes are available from our Web Shop.
