Custom Phage Display Antibody Library

Custom Phage Display Antibody Library

Rx Biosciences offers construction of mouse, human, rabbit, chicken and llamas scFv and Fab libraries in a phagemid vector. Either vL or vH are cloned separately or vL and vH are cloned together, separated by a linker region.  The libraries are good for screening and production of monoclonal antibodies.

+ scFv Light Chain (vL) antibody library in a phagemid vector
+ scFv Heavy Chain (vH) antibody library in a phagemid vector
+ Construction of recombinant vL and vH chimeric antibodies in a phagemid vector
+ Construction of Fab antibody library
+ Construction of (Fab) 2 antibody library
+ Construction of a  library of nanobodies
+ Construction of a bi-specific antibody library (with both domains, recognizing  different targets)
+ Construction of a bi-specific ligand-antibody conjugate (one domain acts like a antibody while other domain acts like a ligand)
+ Construction of camelid and IgNAR antibody libraries

• Secreted expression in periplasm of E. coli.
• Soluble expression in cytoplasm of E. coli.
• Insoluble expressed as inclusion bodies
• Secreted expression in 293 and CHO cells.

• Affinity tag: 6xHis tag.
• Molecular format: insertion of SUMO between His6 tag and protein of interest (POI).
• Purification: IMAC (Immobilized Metal Affinity Chromatography).
• Tag removal after purification: cleavage at the C terminus of SUMO with SUMO protease.
