Abstract:
The present invention provides an in vitro method for obtaining a library of polynucleotides encoding antibodies, derivatives thereof or fragments thereof, comprising the step of performing random mutagenesis of a polynucleotide encoding the variable region of a heavy chain and/or the variable region of a light chain of a light chain, wherein random mutagenesis is performed on a library of polynucleotides comprising a sequence encoding the variable region of a heavy chain and/or the variable region of a light chain; and wherein the random mutagenesis process creates randomly distributed mutations along at least 70% of the sequence encoding the variable region.
Abstract:
A variant of a parent polypeptide including an Fc region, which variant exhibits increased binding to FcRn as compared to the parent polypeptide and includes at least one amino acid modification in the Fc region.
Abstract:
The invention relates to a gene expression inducing fusion protein comprising a) a ribonucleic acid linking peptide domain and a post-transcriptional gene expression activator domain and b) a domain enabling cytoplasmic membrane delocalization. The invention also relates to a modulatable permanent external method for controlling gene expression induction by modulating the state of post-translational modulation of the gene expression inducing fusion protein for the expression of said gene.
Abstract:
This invention relates to an expression cassette for expressing polypeptides in eukaryotic cells using alternative splicing. The expression cassette comprises in 5′ to 3′ downstream direction: a promoter; a sequence transcribed in a 5′ untranslated region (5′UTR); a donor splice site; an intron; a first acceptor splice site; a first cistron encoding a first polypeptide; a second acceptor splice site; a second cistron encoding a second polypeptide; an internal ribosome entry site (IRES) operably linked to a selection marker; and a sequence transcribed in a 3″ untranslated region (3′UTR) including a polyadenylation signal, wherein the polyadenylation signal is unique.
Abstract:
A method for producing a variant of a parent polypeptide including a Fc region, which variant exhibits reduced binding to the protein C1q and to at least one receptor Fcgγ R as compared to the parent polypeptide.
Abstract:
A variant of a parent polypeptide including an Fc region, which variant exhibits increased binding to FcRn as compared to the parent polypeptide and includes at least one amino acid modification in the Fc region.
