Mutated immunoglobulin-binding polypeptides
An Fc-binding polypeptide of improved alkali stability, comprising a mutant of a parental Fc-binding domain of Staphylococcus Protein A (SpA), as defined by SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 22, SEQ ID NO: 51 or SEQ ID NO: 52, wherein at least the asparagine or serine residue at the position corresponding to position 11 in SEQ ID NO: 4-7 has been mutated to an amino acid selected from the group consisting of glutamic acid, lysine, tyrosine, threonine, phenylalanine, leucine, isoleucine, tryptophan, methionine, valine, alanine, histidine and arginine.
CHROMATOGRAPHY LIGAND COMPRISING DOMAIN C FROM STAPHYLOCOCCUS AUREUS PROTEIN A FOR ANTIBODY ISOLATION
The present invention relates to a chromatography ligand, which comprises Domain C from Staphylococcus protein A (SpA), or a functional fragment or variant thereof. The chromatography ligand presents an advantageous capability of withstanding harsh cleaning in place (CIP) conditions, and is capable of binding Fab fragments of antibodies. The ligand may be provided with a terminal coupling group, such as arginine or cysteine, to facilitate its coupling to an insoluble carrier such as beads or a membrane. The invention also relates process of using the ligand in isolation of antibodies, and to a purification protocol which may include washing steps and/or regeneration with alkali.

PEPTIDE-BASED METHODS FOR TREATING NEUROLOGICAL INJURY
Methods for treating and preventing neurodegenerative disease, neurological injury, including stroke, via administration of Transient receptor potential M2 (TRPM2)-inhibitors. The inhibitors may be administered in conjunction with another therapeutic agent or therapeutic regimen. The peptides may be administered to a human male. The peptides may be administered within eight hours of a neurological injury, such as a stroke.

COMPOSITIONS AND METHODS FOR ENTRAPPING PROTEIN ON A SURFACE
The present invention provides a formulation to link protein to a solid support that comprises one or more proteins, Oligo-dT and one or more non-volatile, water-soluble protein solvents, solutes or combination thereof in an aqueous solution. Further provided is a method of attaching a protein to a surface of a substrate. The formulations provided herein are contacted onto the substrate surface, printed thereon and air dried. The substrate surface is irradiated with UV light to induce thymidine photochemical crosslinking via the thymidine moieties of the Oligo-dT.
