MULTIVALENT GLYCAN MICROARRAY PLATFORM
The present invention includes a multivalent glycan microarray for detection of glycan-binding proteins. The multivalent glycan microarray allows a multivalent presentation of glycan on a microarray substrate, which can enhance binding of the glycan binding protein to the glycan microarray. The multivalent microarray includes a solid substrate having one or more branched polymers bonded to it via one or more silane-based linker reagents. The branched polymer in turn is bonded to a glycan, via one or more bifunctional linkers to form the multivalent glycan microarray. Nonspecific binding of glycan binding proteins to the multivalent glycan microarray can be reduced by using a blocking reagent coated on to the microarray substrate, which includes a polyethylene glycol surfactant attached to the solid substrate via a self-crosslinking azido-functionalized silane. Methods for making multivalent glycan microarrays and methods for using same to detect glycan-binding proteins are also disclosed.
METHODS OF ASSAYING PROTEINS
Methods and systems for identifying a protein within a sample are provided herein. A panel of antibodies are acquired, none of which are specific for a single protein or family of proteins. Additionally, the binding properties of the antibodies in the panel are determined. Further, the protein is iteratively exposed to a panel of antibodies. Additionally, a set of antibodies which bind the protein are determined. The identity of the protein is determined using one or more deconvolution methods based on the known binding properties of the antibodies to match the set of antibodies to a sequence of a protein.
INTRA-DROPLET SURFACE ENGINEERING TO CAPTURE A MOLECULAR TARGET
The present invention relates to a method for capturing a molecular target present in the aqueous phase of a water-in-oil emulsion, said method being based on the use of a binding system comprising (a) a surfactant bearing a functional moiety on its hydrophilic head group and (b) a chemoprobe that acts as a molecular staple between the functionalized surfactant and the molecular target and comprises at least two distinct domains namely (i) at least one capture moiety which is able to specifically bind the molecular target and (ii) at least one binding domain which is able to interact with the functional group of the surfactant through covalent or non-covalent interactions, directly or through a binding intermediary.

CANCER-RELATED ACTIVITY SENSORS
An activity sensor sensitive to enzymes indicative of the presence of cancer is used to provide non-invasive reporting of tumor development and response to anticancer therapies useful in determining suitability and effectiveness of various treatments including immuno-oncological therapies. Localized reporters are used in patient stratification in clinical trials, monitoring of drug response or disease progression, and differentiating between anti-tumor immune response, tumor progression, and off-target immune response. Activity sensors may include tuning domains to modulate tissue localization and residency. Periodic measurements of activity sensor reporters may be analyzed to determine a velocity value indicative of disease prognosis.
