The metabolites of polychlorinated biphenyls (PCBs), such as hydroxylated PCBs (OH-PCBs), have been identified as environmental contaminants. Various studies have shown that some OH-PCBs can potentially contribute to health problems. Detection of these compounds in environmental and biological samples could provide useful information about their levels and(More)
Nanoparticle-based therapeutics are poised to play a critical role in treating disease. These complex multifunctional drug delivery vehicles provide for the passive and active targeted delivery of numerous small molecule, peptide and protein-derived pharmaceuticals. This article will first discuss some of the current state of the art nanoparticle classes(More)
Single-domain antibodies (sdAbs), derived from the heavy chain only antibodies found in camelids such as llamas have the potential to provide rugged detection reagents with high affinities, and the ability to refold after denaturation. We have isolated and characterized sdAbs specific to staphylococcal enterotoxin B (SEB) which bind to two distinct epitopes(More)
An increasing interest in applying synthetic biology techniques to program outer membrane vesicles (OMV) are leading to some very interesting and unique applications for OMV where traditional nanoparticles are proving too difficult to synthesize. To date, all Gram-negative bacteria have been shown to produce OMV demonstrating packaging of a variety of cargo(More)
BACKGROUND Single domain antibodies derived from the variable region of the unique heavy chain antibodies found in camelids yield high affinity and regenerable recognition elements. Adding an additional disulfide bond that bridges framework regions is a proven method to increase their melting temperature, however often at the expense of protein production.(More)
All bacteria shed outer membrane vesicles (OMVs) loaded with a diverse array of small molecules, proteins, and genetic cargo. In this study we sought to hijack the bacterial cell export pathway to simultaneously produce, package, and release an active enzyme, phosphotriesterase (PTE). To accomplish this goal the SpyCatcher/SpyTag (SC/ST) bioconjugation(More)
We constructed a genetic fusion of a single domain antibody (sdAb) with the thermal stable maltose binding protein from the thermophile Pyrococcus furiosus (PfuMBP). Produced in the Escherichia coli cytoplasm with high yield, it proved to be a rugged and effective immunoreagent. The sdAb-A5 binds BclA, a Bacillus anthracis spore protein, with high affinity(More)
Single-domain antibodies (sdAbs) derived from heavy-chain only antibodies produced in camelids are attractive immunoreagents due to their small size, high affinity, and ability to refold and retain binding activity after denaturation. It has been observed that some sdAbs, however, exhibit undesirable properties including reduced solubility when subjected to(More)
Single-domain antibodies (sdAbs), the recombinantly expressed binding domains derived from the heavy-chain-only antibodies found in camelids and sharks, are valued for their ability to refold after heat denaturation. However, some sdAbs are prone to aggregation on extended heating at high concentration. Additionally, sdAbs prepared cytoplasmically often(More)
Single domain antibodies, recombinant variable heavy domains derived from the unique heavy-chain only antibodies found in camelids and sharks, are exceptionally rugged due to their ability to refold following heat or chemical denaturation. In addition, a number of single domain antibodies have been found to possess high melting points which provide an even(More)
