摘要:
The present invention relates to a use of a lipid vesicle having bound thereto a targeting polynucleotide and a protein, polypeptide or peptide, which targeting polynucleotide is complementary to a region of a scaffold polynucleotide, to spatially distribute the protein, polypeptide or peptide at a defined position relative to the scaffold polynucleotide.
摘要:
The present invention provides a method for producing a polynucleotide sequence encoding an antibody variable domain, the variable domain comprising complementarity-determining regions (CDRs) located within a selected framework (the 'master framework'), the method comprising the steps of (a) providing at least one nucleic acid molecule encoding one or more CDRs and associated framework regions (the 'original framework'), (b) amplifying at least one CDR-encoding portion of the nucleic acid molecule(s) of step (a) using one or more pairs of oligonucleotides as amplification primers and (c) assembling a polynucleotide sequence encoding an antibody variable domain by combining the amplified CDR-encoding nucleotide sequences produced in step (b) with nucleotide sequences encoding said master framework, wherein the oligonucleotide primers of step (b) comprise nucleotide sequences which differ from the corresponding nucleotide sequences encoding said master framework. The invention further provides an antibody library, such as a phage display library, and methods of making the same.
摘要:
An improved method for selecting a molecule such as an antibody, antigen, peptide, protein or fragment thereof and its encoding sequence, which molecule is expressed together with a phage coat protein on the phages surface. The improvement is achieved through a new mutant filamentous helper phage which has retained the gene III promoter, whereas the gene III encoding sequence is deleted. Amplification of phage titer of 10 times were achieved in M13-derived phages, when used for the selection of specific antibody.

摘要:
A method for the removal of, for in vitro immunisation, undesired cells from human lymphocyte containing cell populations. For the method, use is made of lysosomotropic agents which are caused to act in vitro on human lymphocyte containing cell populations. Also disclosed is a method in the in vitro immunisation of lymphocytes for use in the production of human monoclonal antibodies. In this method, lysosomotropic agents are caused to act in vitro on human lymphocyte containing cell populations for removing cell populations having a negative effect on the in vitro immunisation, whereupon the lymphocytes are in vitro immunised antigen-specifically and immortalised. Finally, a kit for in vitro immunisation of lymphocytes for use in the production of human monoclonal antibodies is disclosed. The kit comprises as active constituents a container containing lymphokines and a container containing lysosomotropic agents.
