Abstract: Disclosed are formulations for enhancing the in vivo colonization of probiotic microorganisms that include digestive enzymes and probiotic microorganisms, and polysorbate surfactants. The enzymes include lactogenic enzyme formulations that promote growth of Lactobacillus probiotics, bifidogenic enzyme formulations that promote growth of Bifidobacterium probiotics and combination formulations that benefit both types of probiotics. It has been discovered that certain polysorbate surfactants, including polysorbate-60 and polysorbate-80, further promote probiotic microorganism growth, when used with the enzyme formulations. The formulations are preferably compounded as dry powders, to avoid water reaction with the enzymes in blended formulations. Such formulations can be contained in capsules, tablets, packets or bottles and administered orally, either sequentially or in one combined formulation.

Abstract: Networks of single-walled carbon nanotubes (SWCNTs) decorated with Au-coated Pd (Au/Pd) nanocubes are employed as electrochemical biosensors that exhibit excellent sensitivity (2.6 mA mM?1 cm?2) and a low estimated detection limit (2.3 nM) at a signal-to-noise ratio of 3 (S/N=3) in the amperometric sensing of hydrogen peroxide. Biofunctionalization of the Au/Pd nanocube-SWCNT biosensor is demonstrated with the selective immobilization of fluorescently labeled streptavidin on the nanocube surfaces via thiol linking. Similarly, glucose oxidase (GOx) is linked to the surface of the nanocubes for amperometric glucose sensing. The exhibited glucose detection limit of 1.3_M (S/N=3) and linear range spanning from 10 ?M to 50 mM substantially surpass other CNT-based biosensors.

Abstract: The present disclosure provides an effective method for the refolding of denatured proteins in solution so that properly folded, biologically active protein in solution is recovered in high yield. The refolding takes place at pressures between about 0.25 kbar to about 3.5 kbar, advantageously at about 1.5 kbar to about 3 kbar. Typically a chaotropic agent is present at a concentration which is not effective for denaturing protein at atmospheric pressure, and optionally, oxidation-reduction reagents can be incorporated in the refolding solution so that native intramolecular disulfide bonds can be formed where that is desired. The method is applicable to substantially all proteins, especially after solubilization and/or denaturation of insoluble protein aggregates, inclusion bodies, or abnormal oligomeric (soluble) aggregates.

Abstract: Compositions and methods are provided for enhancing enzymatic ligation between nucleic acid fragments that relies on one or more small molecule enhancers having a size of less than 1000 daltons. For example, enhancement of ligation efficiencies are observed for double-stranded nucleic acid fragments that are blunt-ended, have a single nucleotide overhang at the ligation end, or have staggered ends compared to ligation under similar conditions in the absence of the one or more small molecule ligation enhancer. The use of small molecule enhancers for ligating nucleic acids results in an increased number of transformed host cells after transformation with the ligated molecules. This enhancement can be observed with chemically transformed host cells and with host cells transformed by electroporation.
