  • Publication number: 20160206732
    Abstract: The present invention provides recombinant protein carrying an epitope. The recombinant protein has a skeleton structure from carrier protein, and a low immunogenic protein epitope is imported through splicing, replacement, and/or insertion to at least one molecular surface amino acid residue area of the carrier protein. The carrier protein has at least one T cell epitope, and the recombinant protein can effectively excite immunoreaction of an organism to the low immunogenic protein epitope.

  • Patent number: 8426150
    Abstract: Provided herein is an affinity media and the construction and use thereof. The affinity media may be used, for example, for the detection of differential proteins/peptides by depletion of proteins/peptides similar to those in a control sample from a test sample in the search for biologically and pathologically important proteins/peptides. The detected differential proteins/peptides provide vital information for biomarker discovery, drug target discovery, and personalized medicine and treatment.

  • Patent number: 8038840
    Abstract: A process for refining and producing cellulose, lignin and xylose from biomass material comprises the following steps: pulverizing and screening the biomass material; and then dipping the biomass material in organic acid with lower boiling point and decomposing it into xylose, xylo-oligosaccharide, cellulose and lignin to make the biomass material fluidify; cooling the fluidified biomass material after finishing the reaction, adding organic solvent, and mixing uniformly and standing; separating, washing and drying the precipitation to obtain amorphous cellulose after precipitating; distilling the mother solution of precipitation of cellulose and recovering the organic acid and the resulting volatile organic substance; standing the distilled mother solution after cooling, and then separating, washing and drying the precipitation to obtain xylose and xylo-oligosaccharide after precipitating; distilling and recovering the organic solvent in the mother solution of precipitation of xylose and xylo-oligosaccharide,

  • Publication number: 20090240033
    Abstract: The invention relates, at least in part, to an affinity matrix library and the construction and use thereof. The library may be used, for example, for the enrichment of low-abundance proteins and depletion of abundant proteins in the search for biologically important proteins. The present invention also relates to a synthetic affinity matrix library comprising one or more ligand compounds with groups selected from amino, sulfhydryl, hydroxyl, carbonyl, and/or active hydrogen. The ligand compound may be attached to a base matrix.

  • Patent number: 6117996
    Abstract: The present invention relates to novel affinity ligand-matrix conjugates comprising a ligand with the general formula (a) ##STR1## which ligand is attached to a support matrix in position (A), optionally through a spacer arm interposed between the matrix and ligand. The invention furthermore relates to these novel affinity ligand-matrix conjugates and the preparation and use thereof in the purification of proteinaceous materials such as e.g. immunoglobulins, insulins, Factor VII, or human Growth Hormone or analogues, derivatives and fragments thereof and precursors.
