Abstract:
Provided herein are aptamer-polymer conjugates which are responsive to environmental stimuli and are useful in selective purification of untagged target polypeptides.
Abstract:
A biosensing FET device, comprising a plurality of nanostructured SOI channels, that is adapted to operate in solutions having a high ionic strength and provides improves sensitivity and detection. Generally, the biosensing device comprises an underlying substrate layer, an insulator and a semiconductor layer and a plurality of channels in the semiconductor layer comprising a plurality of whole or partially formed nanopores in the channels.
Abstract:
A method for sterilizing a membrane comprising an oxidoreductase enzyme in an environment having a relative humidity, comprises: irradiating the membrane comprising an oxidoreductase enzyme with gamma radiation under vacuum at a relative humidity lower than the relative humidity of the environment. Associated biosensors are also described.
Abstract:
A cooling system is provided. The cooling system is associated with a dynamic nuclear polarization system and configured to cool a sample to a temperature suitable for dynamic nuclear polarization to be carried out on the sample while the sample is in the cooling system. The cooling system includes a cryogenic chamber that includes a cryogenic fluid. The cooling system also includes a removable sample sleeve insertable within a portion of the cryogenic chamber. The removable sample sleeve is configured to define a sample path for the sample within the cryogenic chamber that is isolated from other parts of the cooling system.
Abstract:
The present invention is directed to methods of acetate quantification and acetate complexes useful in the methods of acetate quantification. Such methods and complexes are useful for any application where acetate quantification is desired, including measuring of concentration of 13C hyperpolarized acetate for imaging agent quality control in MRI and NMR spectroscopy. The disclosed acetate complexes may be prepared from acetate, Fe3+, and sulfosalicylic acid and from acetate, Fe3+, and salicylic acid.
