A mixed mode affinity chromatography carrier includes a substrate, a hydrophilic polymer, an antibody-binding cyclic peptide, and a cation exchange group.

The invention encompasses formulations and methods for the production thereof that permit the delivery of concentrated protein solutions. The inventive methods can yield a lower viscosity liquid formulation or a higher concentration of therapeutic or nontherapeutic proteins in the liquid formulation, as compared to traditional protein solutions.

The present invention provides a chimeric antigen receptor and natural killer cells expressing the same, and particularly, a chimeric antigen receptor (CAR) which includes an intracellular signaling domain including the whole or a portion of an OX40 ligand (CD252), thereby having excellent effects of increasing anticancer activity of immune cells, and immune cells expressing the same.

The present invention relates to cell culture media comprising 5-Thio-L-fucose and the use of 5-Thio-L-fucose for modulating the glycosylation profile of antibodies or other Fc containing proteins and thereby modulating the binding affinity of said proteins.

This disclosure provides a novel label-free N-glycan analysis method to detect and quantify N-glycans and N-linked glycosylation profiles without using a label, such as a fluorescent label. This method allows for reduced sample preparation and chromatographic separation times, and can be used for product batch release.

Disclosed are a method and a device for constructing an antibody complementarity determining region (CDR) library. Also disclosed are a method, a device and a computer program product for determining the occurrence frequency of member sequences of an antibody CDR library, by means of which an antibody CDR library with a specific amino acid distribution at one or more positions can be obtained.

The present invention generally pertains to methods of quantitating therapeutic proteins co-administered to a subject using LC-MRM-MS. In particular, the present invention pertains to the use of dual enzymatic digestion to generate unique surrogate peptides allowing for the accurate quantitation of co-administered therapeutic proteins using LC-MRM-MS.

The present invention relates to immunoglobulins that bind FcγRIIb+ cells and coengage the antigen on the cell's surface and an FcγRIIb on the cell's surface, methods for their generation, and methods for using the immunoglobulins.
