Meridian Life Science – Vybion Partnership Meridian Life Science – Vybion Partnership ProCodeProCodeTMTM Technology for Antibody Development Technology for Antibody Development
Meridian Life Science, Inc. (MLS) and Vybion have entered into an exclusive agreement to offer a stand–alone technology platform for the development of antibodies that can be engineered into a flexible range of formats. ProCode has demonstrated the ability to select binders from libraries and affinity mature these binders.
ProCode works in two formats allowing for Co-expression Selection of scFv and target as well as a familiar Display Selection format to accommodate a range of targets. Library construction strategies utilized ProCode’s solubility optimized human scFvs (HuSelect) that comprise multiple frameworks and randomized and multiple length CDR inserts. The ProCode technology permits engineering of selected MAbs, develop cell lines and optimize culture through process development.
For Information on How the ProCode Technology Can Help Your Antibody Development; For Information on How the ProCode Technology Can Help Your Antibody Development; Please Contact Dr. Victor Van Cleave ● Vice President of R&D and Contract Manufacturing ● Meridian Life Science, Inc. ● victor.vancleave@meridianlifescience.comPlease Contact Dr. Victor Van Cleave ● Vice President of R&D and Contract Manufacturing ● Meridian Life Science, Inc. ● victor.vancleave@meridianlifescience.com
HuSelect scFv libraries with novel modified leaders are expressed on the inner E. coli membrane. Fluorescent antigen target binds, and is selected, for example, by FACS after the cell wall is permeabilized.
HuSelect scFv libraries with novel leaders are co-expressed with target antigen fused to antibiotic resistance gene. Only soluble scFvs that bind to target confer antibiotic resistance following transport. Antibiotic pressure selects, in multiple rounds, for higher affinity.
ProCode Technology Features:ProCode Technology Features:► Novel transport ‘self edits’ for folded proteins only► Solubility optimized scFv libraries► Multiple libraries each with unique frameworks and synthetic randomized CDRs ► Two selection modes can accommodate a range of targets or specific target epitopes► Target binding epitope mapping by display of overlapping target sequences
ProCode Advantages:ProCode Advantages:► Rapid affinity maturation to low pM► Complete panelsComplete panels of high affinity binders in a few weeks. More effective functional screening.► Stand-alone technology► Better stability, lower aggregation► Effective in oxidizing and reducing environments► Reduced time to market
