摘要:
Provided is an approach for achieving the expansion of a human antibody repertoire in a human antibody-producing non-human animal. Provided is a mammalian artificial chromosome vector comprising a human immunoglobulin heavy chain locus in which a D-region of a human immunoglobulin heavy chain is modified, and a human immunoglobulin light chain locus, a mammalian cell or a non-human animal comprising this mammalian artificial chromosome vector, and a method for substituting a D-region of a human immunoglobulin heavy chain with a modified sequence thereof in the production of this artificial chromosome vector.

An anti-soluble CD14 subtype monoclonal antibody or an antigen-binding antibody fragment thereof specifically recognizes an epitope composed of the amino acid sequence of SEQ ID No. 84. A kit for detecting the soluble CD14 subtype, a method for detecting the soluble CD14 subtype and corresponding use.

[Problem] An object of the present invention is to provide a means that makes it possible to obtain an antibody that specifically binds to the conformational epitope of a protein antigen and to produce a variety of monoclonal antibodies with unique specificity even in the case of conducting a booster. [Solution] A non-human animal (animal for immunization) is immunized by intradermal administration of a protein antigen, antibody-producing cells are obtained from a regional lymph node corresponding to the administration site for the above antigen in the immunized animal, and a monoclonal antibody is made by hybridoma technology as described above.

The present invention provides mammalian cell lines that have been genetically engineered causing such cell lines to be resistant to viral entry and/or propagation, and provides methods of using said cell lines to reduce or prevent viral contamination of biologic production systems.
摘要:
Pork-specific PCR assay is performed for Halal authentication, by detecting porcine DNA in food products. DNA from raw meat samples is extracted. The extracted DNA is tested using primers that react by amplifying pork DNA but not beef and chicken DNA. The real-time PCR assay is sensitive with a low detection limit when using samples that can be obtained from food products. The methods described herein can have a sensitivity threshold as low as 0.001 ng pork DNA or lower, whereas convention techniques typically do not have a detection limit lower than 0.1 ng pork DNA.
