摘要： A modified igNAR peptide sequence derived from a wild-type igNAR peptide sequence is diversified by mutating the amino acid sequence at 50% or more of the amino acids in the CDR3 loop region and optionally at 50% or more of the amino acids in the CDR3 loop region. The modified igNAR peptide may have the sequence of SEQ ID NO: 8, 10 or 50 to 85. The modified igNAR peptides have binding activity against albumin protein sequences, such as human serum albumin. These modified igNAR peptides may have utility in extending the in vivo half-life of biological molecules e.g. therapeutic agents, and so may be used in medicine.

摘要： A method is provided for selecting membrane-translocating peptides (MTPs) from a peptide display library that are capable of crossing or penetrating a lipid membrane. A plurality of nucleic acid constructs that encode displayed peptides are expressed, resulting in the formation of a plurality of nucleic acid-peptide complexes, each complex comprising at least one displayed peptide associated with the corresponding nucleic acid construct encoding the displayed peptide; the complexes are exposed to a population of membrane-encapsulated compartments, allowing a translocating reaction to occur; complexes that remain unassociated with the membrane are removed; optionally complexes that are associated with the membrane are removed; and internalised nucleic acid-peptide complexes are recovered. The membrane-encapsulated compartments may be artificial vesicles such as liposomes, or populations of one or more cell types.

摘要： The invention provides a method for making in vitro peptide expression libraries, and for the isolation of nucleotide sequences encoding peptides of interest, wherein the peptides or proteins are specifically associated with the DNA encoding them through non-covalent protein:DNA binding. The method describes ways of making the library itself, DNA molecules encoding the library and uses of the expression library.

摘要： There is described a method of isolating nucleotide sequences encoding target peptides from DNA libraries using DNA binding proteins to link the peptide to the sequence which encodes it. DNA libraries are prepared from cells encoding the protein of interest, or from synthetic DNA, and inserted into, or adjacent to, a DNA binding protein in an expression vector to create a chimeric fusion protein. Incorporation of the vector DNA into a carrier package, during expression of the chimeric fusion protein, results in the production of a peptide display carrier package (PDCP) displaying the DNA-bound fusion protein on the external surface of the carrier package. Employment of affinity purification techniques results in the PDCP particles containing sequences encoding the desired peptide to be selected and the desired nucleotide sequences obtained therefrom.
