We have developed a universal ovarian cancer cell targeting vehicle that can deliver biotinylated therapeutic drugs. A single-chain antibody variable domain (scFv) that recognizes the CA125 antigen of ovarian cancer cells was fused with a core-streptavidin domain (core-streptavidin-VL-VH and VL-VH-core-streptavidin orientations) using recombinant DNA(More)
PURPOSE The purpose of this study is to develop a simple and inexpensive method for detection of viral load or antigens present in the body fluids as for diagnosis or monitoring of infectious diseases. For example, in case of viral infection, nucleic acid based quantitative PCR/RTPCR are sensitive in measuring viral load to follow the course of therapy or(More)
We have developed a universal DC targeting vehicle that could be a convenient method to deliver any type of antigen to DC. P125, a quadroma (hybrid-hybridoma) secreting bispecific monoclonal antibodies (bsmAb), with one paratope specific for mouse DC DEC-205 and another paratope specific for biotin, was developed by PEG-fusion of the two parental hybridomas(More)
A sandwich ELISA technique was examined to detect Escherichia coli O157:H7 using chicken anti-E. coli O157:H7 IgY as the capture-antibody and an anti-E. coli O157 mouse mAb conjugated with biotin as the detection antibody. The anti-E. coli O157:H7 IgY was harvested from eggs laid by hens (23 weeks of age, Single Comb White Leghorn) immunized with(More)
We have developed an efficient versatile in vivo dendritic cell (DC) targeting vector for delivering different classes of antigens such as proteins, peptide, glycolipids and naked DNA for vaccine applications. A single chain antibody (scFv) that recognizes DEC-205 receptor of DC was fused with a core-streptavidin domain and expressed in Escherichia coli(More)
We have successfully cloned and expressed core-streptavidin in Escherichia coli. Core-streptavidin was expressed in shaker flask culture as a soluble protein, isolated by periplasmic extraction, purified by immobilized metal affinity chromatography column, and analyzed for its size, thermal stability, and biotin-binding activity. In Western blots using(More)
