Diagnosis of Epstein-Barr virus infection in clinical serum samples by an SPR biosensor assay.

Label-free affinity biosensors offer a promising platform for the development of a new generation of medical diagnostic technologies. Nevertheless, when such sensors are used in complex biological media, adsorption of non-targeted medium components prevents the specific detection of the analyte. In this work, we introduce for the first time a biosensor assay based on surface plasmon resonance (SPR) capable of diagnosing different stages of Epstein-Barr virus (EBV) infections in clinical serum samples.

Influence of immunization with non-genotoxic PAH-KLH conjugates on the resistance of organisms exposed to benzo(a)pyrene.

Polycyclic aromatic hydrocarbons (PAH) are recognized as common environmental pollutants released into the environment from many natural as well as man-made sources, and some have been classified as potent carcinogens. The main representative of the carcinogenic PAH is benzo(a)pyrene (B(a)P) which is known to induce genotoxic effects in vitro and in vivo, detected as PAH-DNA adducts. Long-term PAH exposure may be accompanied by an immunological response with the formation of antibodies against PAH as well as against PAH-DNA adducts.

Isolation and properties of gene-modified mouse bcr-abl-transformed cells expressing various immunostimulatory factors.

Unlabelled: B210 cells are murine (BALB/c) cells transformed by bcr-abl fusion gene. After intravenous administration they are capable of inducing leukaemia-like disease in syngeneic mice. From these cells a thymidine-kinase less subline was derived.

The Bloodgen Project of the European Union, 2003-2009.

The Bloodgen project was funded by the European Commission between 2003 and 2006, and involved academic blood centres, universities, and Progenika Biopharma S.A., a commercial supplier of genotyping platforms that incorporate glass arrays.

Live cell vaccines expressing B7.1, monocyte chemoattractant protein 1 and granulocyte-macrophage colony stimulation factor derived from mouse HPV16-transformed cells.

One of the gene therapy strategies in oncology is immunization with cancer cells that express various cytokines. We used a thymidine-kinase deficient (cTK-) cell line designated 123IA, which had been derived from HPV16-transformed mouse (C57BL/6) cells MK16/I/III/ABC (MK16). To obtain genetically modified cells, 123IA cells were transfected with bicistronic plasmid vectors carrying the herpes simplex type 1 thymidine kinase (HSV TK) gene and either the gene for the mouse B7.
