AFFINITY PURIFICATION OF GLYCOSIDE-CLEAVING ENZYMES
The invention relates to an affinity resin functionalized with small molecule inhibitors of glycoside-cleaving enzymes, e.g., -galactosidase A (-Gal A), glucocerebrosidase (GCB), -galactosidase, and acid alpha-glucosidase (GAA), and a method for purifying glycoside-cleaving enzymes produced in a cell line using the small molecule inhibitor-functionalized affinity resin.
ANIONIC EXCHANGE-HYDROPHOBIC MIXED MODE CHROMATOGRAPHY RESINS
Chromatography resins having anionic exchange-hydrophobic mixed mode ligands and methods of using such resins are provided.
DESALINATION OF WATER USING A COMPLEXING AGENT ATTACHED TO A MAGNETIC NANOPARTICLE
There is disclosed, a desalination apparatus making use of a particles including covalently bonded functionalized magnetic nanoparticles coupled to a complexing agent. For example, the complexing agent may include a crown ether. The particles are optionally used for removing salt from water, for example sea water. The apparatus optionally includes a magnet for magnetic filtering, concentrating and/or removing the particles and/or contaminant (e.g., salt). In some embodiments, the salt is then separated back from the particles using UV light. The remaining unclarified water may be washed out with the contaminant and/or used for salt production and/or disposed of (e.g., dumped back to the sea). Optionally, the particles are regenerated. For example, the regenerated particulars may be reused for further desalination steps (e.g., further salt removal from the clarified water) to clarify new input water. Covalently bonded functionalized magnetic nanoparticles coupled to a complexing agent are also disclosed.
SURFACE FUNCTIONALISED MATERIALS FOR SAMPLING BIOLOGICAL MOLECULES
The invention relates to materials, methods and devices useful for sampling biological molecules, including biomarkers and/or metabolites. In particular, the invention relates to surface functionalised xerogels and surface functionalised poly(dimethyl) siloxane (PDMS), devices comprising those materials, and methods of using the materials and devices for sampling, analysing or detecting biological molecules.
Bifunctional Absorptive Material Capable of Absorbing Both Cations and Anions in Aqueous Phase
This present invention discloses a bifunctional adsorptive material capable of adsorbing both cations and anions in aqueous phase, obtainable by synthesizing aluminum ion doped SBA-15 molecular sieves from P123 triblock copolymers, tetraethoxysilane, and aluminum isopropoxide to obtain multiple cationic active adsorption sites, and by grafting large sterically hindered organic groups onto the surface of Al-SBA-15 to obtain multiple anionic active adsorption sites. This kind of adsorptive material has two types of adsorption sites for ions of opposite charges. The large sterically hindered organic groups prevent spontaneous recombination reaction between the two types of adsorption sites, enabling the adsorptive material to have excellent adsorption capacity for wastewater treatment involving both cations and anions.
SYNTHETIC RECEPTORS FOR IONOPHORIC COMPOUNDS
The present invention relates to synthetic receptors for ionophoric compounds, such as ionophoric toxins. Hence, the invention provides synthetic molecules capable of binding different ionophoric compounds, thereby being suitable for use in the detection, isolation and detoxification of such ionophoric compounds. The present invention further provides the use of such synthetic receptors in human and veterinary medicine, such as in the diagnosis, prevention and/or treatment of disorders caused by such ionophoric compounds. Finally, the invention provides methods of preparing such synthetic receptors for ionophoric compounds.
HYBRID LIGAND, HYBRID BIOMIMETIC CHROMEDIA AND PREPARING METHOD AND USE THEREOF
This invention relates to a hybrid ligand, a hybrid biomimetic chromedia and a preparing method and a use thereof, wherein the hybrid biomimetic chromedia takes hydrophilic porous microsphere as a substrate in chromatography, activated with allyl bromide and undergoing bromo-alcoholization with N-bromosuccinimide, then coupled with the hybrid ligands. The sequence of the hybrid ligand is phenylalanine-tyrosine-glutamine-5-aminobenzimidazole. The hybrid biomimetic chromedia has both of the two functional groups of phenylalanine-tyrosine-glutamine tripeptide and aminobenzimidazole, while maintaining the high antibody selectivity of polypeptide ligand, hydrophobic electric charge inductive ligand is introduced to achieve more moderate elution requirement, realizing effective antibody separation.
ANIONIC EXCHANGE-HYDROPHOBIC MIXED MODE CHROMATOGRAPHY RESIN
Chromatography resins having anionic exchange-hydrophobic mixed mode ligands, that are useful for purifying target biomolecules using anionic exchange (i.e., where the ligand is positively charged) and hydrophobic mixed mode chromatography. The chromatography resins allow for efficient purification of target biomolecules (e.g., recombinant proteins, antibodies, antibody-drug conjugates, or antibody derivatives including, but not limited to, antibody fragments and antibody fusions) from a sample, and have been found to be useful in purifying monomeric target biomolecules from aggregate target biomolecules. In an embodiment, the chromatography resins are useful for separating antibodies from one or more components (e.g., contaminants) in the sample.
INTEGRATION OF EX SITU FABRICATED POROUS POLYMER MONOLITHS INTO FLUIDIC CHIPS
Bare porous polymer monoliths, fluidic chips, methods of incorporating bare porous polymer monoliths into fluidic chips, and methods for functionalizing bare porous polymer monoliths are described. Bare porous polymer monoliths may be fabricated ex situ in a mold. The bare porous polymer monoliths may also be functionalized ex situ. Incorporating the bare preformed porous polymer monoliths into the fluidic chips may include inserting the monoliths into channels of channel substrates of the fluidic chips. Incorporating the bare preformed porous polymer monoliths into the fluidic chips may include bonding a capping layer to the channel substrate. The bare porous polymer monoliths may be mechanically anchored to channel walls and to the capping layer. The bare porous polymer monoliths may be functionalized by ex situ immobilization of capture probes on the monoliths. The monoliths may be functionalized by direct attachment of chitosan.
