Abstract:
The invention is directed to an assay for acid β-galactosidase activity. The invention may include combining in oil a sample droplet with a 4-methylumbelliferyl-B-galactose to yield a reaction droplet; splitting the reaction droplet to yield a first daughter droplet and a second daughter droplet; combining the first daughter droplet with a stop buffer droplet to yield a first stopped reaction droplet; incubating the second daughter droplet; combining the second daughter droplet with a stop buffer droplet to yield a second stopped reaction droplet; and measuring 4-methylumbelliferone released in the first and second stopped reaction droplets.
Abstract:
Some aspects of this invention provide a non-human animal model of autism. Some aspects of this invention provide a non-human animal model for diseases or disorders associated with an overexpression or a copy number variance of a Ube3a gene. Transgenic mammals and transgenic mammalian cells comprising an exogenous copy or exogenous copies of a ube3a protein-encoding nucleic acid sequence are also provided. Some aspects of this invention further provide methods for using the animal models, cells, and transgenic animals for identifying agents or interventions that can alleviate a pathogenic characteristic observed in the animal model, cell, or transgenic animal.
Abstract:
The present invention refers to the gene cluster and genes comprised by the gene cluster which are involved in the biosynthesis of griselimycin and methylgriselimycin and to the use of the gene cluster, genes comprised thereby and proteins encoded thereby for the production of antibiotic agents.
Abstract:
The invention generally relates to methods for quantifying an amount of enzyme molecules. Systems and methods of the invention are provided for measuring an amount of target by forming a plurality of fluid partitions, a subset of which include the target, performing an enzyme-catalyzed reaction in the subset, and detecting the number of partitions in the subset. The amount of target can be determined based on the detected number.
Abstract:
Methods of identifying immune response modulators are disclosed. Some methods comprise identifying chemical candidates that modulate oligomerization of FOXP3 and/or fragments thereof comprising the Zinc-LeuZip domains. Some methods comprise identifying chemical candidates that modulate the hetero-oligomerization of FOXP1 with FOXP3 and/or fragments thereof comprising the Zinc-LeuZip domains. Some methods comprise identifying chemical candidates that modulate interaction of IL-2 promoter with FOXP3 and/or fragments thereof comprising the Zinc-LeuZip domains. Method of treating individuals who have or are suspected of having autoimmune disease, inflammatory disease, cell, tissue or organ transplantation, or coronary artery disease, and methods of treating individuals who have or are suspected of having infectious disease, cancer, or who are immunocompromised or undergoing vaccination are disclosed.
Abstract:
The present invention discloses a cell culturing formulation and a culturing and quantification method of CD140b+ cells thereof. The cell culturing formulation is applicable for inducing the growth of the CD140b+ cells in peripheral blood. The cell culturing formulation comprises a culturing medium, a serum, a mixed additive and a defined factor. Wherein, concentrations of the culturing medium, the serum, the mixed additive and the defined factor are 59˜98% (v/v), 0.1˜20% (v/v), 1˜10% (v/v) and 10−7˜10% (v/v) respectively.
Abstract:
A packet of an enzyme and/or enzyme producing bacteria is contained within the core of a roll of toilet tissue or similar paper product wound on a core. The packet has a cover that dissolves or disintegrates on contact with water and disperses its contents into the aqueous waste stream. The packet may contain a mixture of bacterial cultures that produce enzymes to attack the greasy or fatty components of the waste stream. An additional article such as a sample of a liquid or creme personal care product may also be contained within the tissue paper core.
Abstract:
Provided is a novel ubiquitin ligase which has linear polyubiquitination activity and can be efficiently expressed and purified. It was found out that a complex of (a) a protein having a part of HOIP and at least having a UBA region and a RING-IBR-RING region thereof, and (b) One or more kinds of proteins which individually form a complex with the above (a) is a novel ubiquitin ligase which has linear polyubiquitination activity and can be efficiently expressed and purified.
Abstract:
The present invention relates to compounds useful for measuring aromatase activity. The invention further provides methods for measuring aromatase activity and for screening test agents which modulate aromatase activity. A kit is also provided for use in such screening methods.
Abstract:
A particulate body having a hollow particle and a surface polymer disposed on the outside of the hollow particle and suitable for use in solid phase synthesis, especially production of peptides and oligonucleotides. The particulate body may be used as a chromatography stationary phase column and the buoyancy of the body allows the column to be packed efficiently from the bottom reducing the risk of damage to the stationary phase. The buoyancy of the particulate body may also allow species for example a catalyst to be suspended in a liquid phase to allow reactions, for example hydrolysis of vegetable oil and esterification to produce biodiesel to be carried out with a reduced risk of catalyst loss from a reaction zone.
