A method for cloning a full length coding sequence for a light chain of a rabbit monoclonal antibody is provided. In some embodiments, this method may involve: fusing a B cell from a rabbit having a B4 allotype with a 240E cell or a derivative thereof to produce a hybridoma, wherein the B cell and the hybridoma produce a monoclonal antibody; making cDNA from the hybridoma; amplifying from the cDNA a full length coding sequence for the light chain of a monoclonal antibody produced by the hybridoma using: a forward primer that hybridizes to a site in SEQ ID NO: 10, and a reverse primer having a 3′ end of sequence CTARCAGTCX (SEQ ID NO: 11), wherein R is A or G and X is A, AC, ACC or ACCC; and cloning the amplified sequence into an expression vector to produce a first plasmid.

Combinations of different chromatography modalities with particularly refined conditions significantly reduce acid charge variants in a preparation of monoclonal antibodies. The process for reducing acid charge variants utilizes a combination of anion exchange and hydrophobic interaction chromatography, followed by cation exchange chromatography polishing, whereby the levels of acidic or basic charge species of the monoclonal antibodies may be modulated to a desired level.

Antibodies and compositions against IGF-1R and uses thereof are provided herein.

Methods are disclosed for treating osteoarthritis in a human subject in need thereof, comprising administering to the subject a therapeutically effective amount of an anti-human NGF antibody, or antigen-binding fragment thereof, wherein at least one symptom associated with osteoarthritis is prevented, ameliorated or improved.

The present disclosure provides methods comprising administering to the individual an effective amount of an agent that decreases or inhibits TIGIT expression and/or activity and an anti-cancer agent and/or an anti-cancer therapy. Further provided are kits comprising an anti-cancer agent, an agent that decreases or inhibits TIGIT expression and/or activity, or both, as well as instructions for use thereof.

The present disclosure provides materials and methods for cloning antibodies from single cells in pooled sequence libraries by selective PCR. The compositions and methods relate to isolating, cloning, and/or expressing one or more antibody sequences from a single cell from a pool of cells.

The present invention relates to compositions and methods for the prevention or the treatment of lung cancer, wherein the compositions comprise an antibody binding to progastrin and the methods comprise the use of an antibody binding to progastrin.

The present disclosure generally relates to viral-based expression systems suitable for the production of molecule of interests in recombinant host cells. The disclosure particularly relates to nucleic acid constructs, such as expression vectors, containing a modified arterivirus genome or replicon RNA in which at least some of its original viral sequence has been deleted. Also included in the disclosure are viral-based expression vectors including one or more expression cassettes encoding heterologous polypeptides. In some embodiments, the expression cassettes are configured and positioned at defined locations on the viral genome so as to enable expression of the heterologous polypeptides in a tunable manner.

Antibodies and antibody fragments that inhibit the activity of vascular cell adhesion molecule 1 (VCAM1) and/or macrophage erythroblast attacher (MAEA) are provided, along with formulations and kits comprising these antibodies and antibody fragments and the use of the disclosed compositions, formulations, and kits to treat cancers, sickle cell disease, and Polycythemia Vera.

Disclosed is a method for improving affinity of an antibody for an antigen, comprising, in an unmodified antibody, improving affinity for an antigen as compared to the unmodified antibody, by changing 17th, 18th and 20th amino acid residues of a light chain defined by Kabat method to charged amino acid residues.
