Abstract:
Disclosed herein is a method of designing small peptides for interacting with, binding to, or modulating the activity of, known protein or peptides. Further disclosed herein are methods for selecting sequences likely to have high binding activity against known protein sequences as well as peptides derived from the disclosed methods.
Abstract:
A method for determining the molecular binding between a target molecule library and a binder molecule library is provided including contacting the target molecule library comprising a plurality of mRNA-protein conjugates with the binder molecule library comprising a plurality of mRNA-protein conjugates under conditions where one or more proteins in the target library bind to one or more proteins in the binder library, and determining the molecular binding of the target and binder protein pairs by determining the sequences of the mRNAs conjugated to the target and binder protein pairs.
Abstract:
The present invention provides a regenerated cellulose membrane (RCM) that is useful in analysis of a sample for the presence of or the amount of a target molecule present in the sample. The invention also provides a method for producing and using the same. The RCM of the invention has a plurality of RCM functional groups on its surface in which a linker is covalently attached. The linker has a distal end and a proximal end, where the proximal end comprises at least one RCM linking functional group such that the RCM linking functional group is attached to the RCM functional group. The distal end of the linker comprises a receptor linking functional group that is used to covalently attach a receptor molecule. The receptor molecule is adapted for binding to a target molecule of interest when the target molecule is present in the sample. The RCM of the invention can be used for quantitative and/or qualitative analysis of a target molecule within the sample. The present invention also provides a method for producing and using the linker.
Abstract:
The present invention relates to methods for high multiplex protein or cellular constituent analysis in single cells or single isolated aggregations of cellular constituents. The methods provide for embedding cells or isolated aggregations of cellular constituents in a hydrogel mesh and labeling of cellular constituents with labeling ligands linked to a nucleic acid tag. Cellular constituents can be determined using sequencing methods.
Abstract:
Antibody-based methods of detecting of molecules interacting with a target molecule, such as a nuclear or cytoplasmic protein, in a fixed and, optionally, permeabilized cell or tissue sample. In one example, the target molecule is bound by a primary antibody, and a secondary, peroxidase-conjugated antibody, then binds to the primary antibody. The peroxidase may also be conjugated the primary antibody. Biotin tyramide is added to the sample, and the peroxidase generates short-lived intermediates resulting in biotinylation of molecules adjacent to the peroxidase. Biotinylated molecules can be isolated from the sample by affinity interaction with avidin- or streptavidin, resulting in a fraction containing biotinylated molecules that are located in the sample in proximity to the target molecule. The fraction can be analyzed by mass-spectroscopy, Western blotting, sequencing and other techniques.
Abstract:
Aspects of the present disclosure provide a platform that triggers potent and effective immunotherapy against tumors from within tumors themselves, thus overcoming limitations of existing cancer immunotherapies and tumor-detecting gene circuits.
Abstract:
It has been demonstrated that certain compounds bind to TNF and stabilise a conformation of trimeric TNF that binds to the TNF receptor. Antibodies which selectively bind to complexes of such compounds with TNF superfamily members are disclosed. These antibodies may be used to detect further compounds with the same activity, and as target engagement biomarker.
Abstract:
It has been demonstrated that certain compounds bind to TNF and stabilise a conformation of trimeric TNF that binds to the TNF receptor. Accordingly, these compounds can be used as modulators of TNF. Anew assay for identifying compounds with this mechanism of action is also disclosed.
Abstract:
Methods and apparatus are provided for screening libraries of polypeptides linked to coding sequences for a biological activity. Libraries of nucleic acid molecules encoding candidate polypeptides, such as antibodies, can be amplified, expressed, and linked to beads. The library allows for efficient high-throughput screening to identify polypeptides having a desired biological activity. In some aspects, amplification, expression, and/or screening is performed in a high-density pico-, nano-, or micro-well plate format. Methods and compositions for efficient expression and screening of antibodies are likewise provided.
