摘要:
Purified DNA encoding .alpha.(1,3)fucosyltransferase and the recombinant proteins expressed from such DNA are disclosed. The recombinant fucosyltransferase polypeptides are used to fucosylate proteins to produce therapeutics useful for the treatment of disease, e.g., an adverse immune reaction such as septiciemia or septic shock.
摘要:
Disclosed is a method of isolating a protein from a sample, involving (i) providing a first molecule which is capable of forming an affinity complex with the protein; (ii) contacting the sample with the first molecule under conditions which allow affinity complex formation; (iii) isolating the complex; (iv) treating the complex with imidazole to disrupt the complex, causing the release of the protein from the complex; and (v) isolating the protein. According to one embodiment, imidazole is used as a very gentle elution reagent to disrupt a protein A-antibody fusion protein complex, a technique which has general application for the isolation of antibodies or recombinant antibody fusion proteins.
摘要:
Disclosed is a method of inhibiting the binding of a cell bearing a cell adhesion protein to a molecule or cell bearing a carbohydrate determinant specific for the cell adhesion molecule. The method involves contacting the cell adhesion protein-bearing cell with an inhibitor molecule bearing the carbohydrate determinant. Also disclosed is a method of inhibiting the binding of the first member of a specific binding pair to the second member of the specific binding pair, involving contacting the first member with an antibody which is specific for the first member and which is covalently bonded to a carbohydrate moiety which interferes with the antibody's ability to fix complement and bind an F.sub.c receptor. The methods of the invention may be used, for example, to reduce inflammation.
摘要:
The present invention relates, in general, to substantially pure polynucleotide molecules specifying chimpanzee or rhesus monkey CD4, and fragments thereof and Gp120 binding molecules related to human CD4. The present invention further relates to polynucleotide molecules specifying CD4 fusion proteins and host cells containing the polynucleotide molecules.
摘要:
Fusion proteins are obtained in high yields if a mixed oligonucleotide is constructed which codes for the ballast constituent of the fusion protein. The oligonucleotide mixture is introduced in a vector in such a manner that it is functionally linked to a regulatory region and to the structural gene for the desired protein. Appropriate host cells are transformed with the plasmid population obtained in this manner and the clones producing a high yield of coded fusion protein are selected.
摘要:
Provided are compounds having an inhibitory effect on sodium-dependent glucose cotransporter SGLT. The invention also provides pharmaceutical compositions, methods of preparing the compounds, synthetic intermediates, and methods of using the compounds, independently or in combination with other therapeutic agents, for treating diseases and conditions that are affected by SGLT inhibition.
摘要:
The invention features compositions based on thioredoxin-like fold protein domains described as engineered thioredoxin-like fold proteins (ETRXs). These proteins include one or more artificially diversified thioredoxin-like fold protein domains; each domain may be originated from the same or different thioredoxin-like fold protein domains. Features of the invention also include methods for identifying and preparing an enriched composition of target binding, loop-diversified ETRXs with additional sequence variations to improve affinity, stability, selectivity, or solubility. The invention also features compositions of ETRXs substituted with prosthetic groups, polymers, proteins, nucleic acids, carbohydrates, metals, natural or synthetic small molecules and toxins.
