Abstract:
A method of measuring acidic species generated by degradation of a Fab or Fab′ component of a Fab-PEG or a Fab′-PEG is provided. The method involves: a) cleaving PEG and a linker from the Fab-PEG or Fab′-PEG with an enzyme; b) optionally separating the PEG and linker from the Fab or Fab′ to provide isolated Fab or Fab′; and c) quantitatively analyzing acidic species associated with the cleaved Fab or Fab′ and/or the cleaved PEG.

Abstract:
The present invention provides a multivalent antibody or a heavy/light chain component thereof comprising: a heavy chain comprising a constant region fragment, said constant region fragment located between two variable domains which are not a cognate pair, the heavy chain further comprising an Fc region with at least one domain selected from CH2, CH3 and combinations thereof, with the proviso that the heavy chain contains no more than one CH1 domain and only contains two variable domains, and a light chain comprising a constant region fragment located between two variable domains which are not a cognate pair, wherein said heavy and light chains are aligned to provide a first binding site formed by a first cognate pair of variable domains and a second binding site formed by a second cognate pair of variable domains.
Abstract:
The present invention relates to a process for the purification of an antibody fragment from a periplasmic cell extract comprising a first cation exchange chromatography step and a second anion exchange chromatography step.
Abstract:
The present invention provides dual specificity antibody fusion proteins comprising an antibody Fab or Fab′ fragment with specificity for an antigen of interest, said fragment being fused to at least one single domain antibody which has specificity for a second antigen of interest.
Abstract:
The present invention provides a recombinant gram-negative bacterial cell comprising an expression vector comprising a recombinant polynucleotide encoding DsbC and one or more polynucleotides encoding an antibody or an antigen-binding fragment thereof specifically binding to CD154.
Abstract:
Compositions and methods relating to antibodies that specifically bind to TGF-beta binding proteins are provided. These methods and compositions relate to altering bone mineral density by interfering with the interaction between a TGF-beta binding protein sclerostin and a TGF-beta superfamily member, particularly a bone morphogenic protein. Increasing bone mineral density has uses in diseases and conditions in which low bone mineral density typifies the condition, such as osteopenia, osteoporosis, and bone fractures.
