Abstract: ELISA-type assays, lateral flow test strips, methods, and systems are provided for detecting APOL1 G0 in bodily samples including blood, serum, or plasma to provide a rapid rule-in test for the ApoL1 G0 genotype. The assays exploit the differential affinity of serum resistance-associated protein (SRA) for wild-type APOL1 (designated ‘G0’) over the other variants G1 and G2 to specifically detect APOL1 G0. Results with human plasma samples (N=130) from all six genotypes (G0/G0, G0/G1, G0/G2, G1/G2, G2/G2, G1/G1) show the assay can detect APOL1 G0 from plasma with 100% concordance with genotyping. The assay fulfills an unmet need for a rapid test (i.e., within about an hour) for determining APOL1 variant status in deceased kidney donors which represent 72% of donated kidneys.

Abstract: Compositions and methods for tissue repair are provided including cell binding peptides and growth factor binding peptides. The cell binding peptides bind to one or more of stem cells, fibroblasts, or endothelial cells. The growth factor binding peptides include platelet derived growth factor (PDGF) binding peptides and growth differentiation factor (GDF) binding peptides. The tissue for repair includes tendon, muscle, connective tissue, ligament, cardiac tissue, vascular tissue, or dermis. Implantable devices for tissue repair are provided to which the cell and growth factor binding peptides are attached, such as acellular extracellular matrix having attached binding peptide.

Abstract: Compositions and methods are provided for capturing cells. Cell binding peptides are provided that bind to one or more of stem cells, fibroblasts, or endothelial cells. In the methods, a sample containing cells is contacted with a cell binding peptide attached to a substrate, and the cells present in the sample are captured onto the substrate through binding to the cell binding peptide.

Abstract: Compositions and methods are provided for promoting bone growth. An implantable bone graft material is provided comprising a resorbable ceramic and a resorbable polymer, wherein the polymer comprises a covalently attached stem cell binding peptide. The implantable bone graft materials are useful for promoting bone growth in a subject.

Abstract: The presently disclosed subject matter relates to peptides having binding affinity for glycopeptide antibiotics and methods and compositions for delivering glycopeptide antibiotic to the surface of medical devices. The peptide compositions can comprise a peptide having binding affinity for a surface material of a medical device that is coupled to the peptide having binding affinity for glycopeptide antibiotic. Also provided are methods of applying the peptide compositions to a medical device by contacting the peptide compositions with a surface of the medical device. In addition, kits are provided comprising the peptide compositions.
