small standard deviations of 0.11 and 0.39 pg/ml, respectively. Additional studies demonstrated that the recovery of 0.13, 0.35, 0.62, 2.7, 24, and 260 pg/ml VEGF in 10% pooled mouse EDTA plasma was 100– 120%; the average recoveries of 2, 5, and 20 pg/ml VEGF in 10% individual human serum (n 5 4, with 98–130 pg/ml endogenous VEGF) were 83, 94, and 96%, respectively. This immuno-PCR therefore ca...

Accumulating experimental evidence indicates that overexpression of the oncogenic receptor tyrosine kinase, Axl, plays a key role in the tumorigenesis and metastasis of various types of cancer. The objective of this study is to design a novel imaging probe based on the monoclonal antibody, h173, for microPET imaging of Axl expression in human lung cancer. A bifunctional chelator, DOTA, was conj...

We performed an immunoassay evaluation for various analytes on a fully automated random-access analyzer, the Technicon Immuno 1 system from Bayer Corp. This system involves latex agglutination, magnetic separation sandwich, and magnetic separation competitive immunoassay configurations. The evaluated analytes were thyrotropin (TSH), triiodothyronine, thyroxine, free thyroxine, follitropin, lutr...

Poisoning with cardiac glycoside-containing plants is collectively the most important plant-associated poisoning of livestock in southern Africa. As a diagnosis of this significant poisoning is currently based on circumstantial evidence, a practical chemical procedure indicating the presence of cardiac glycosides in plants and animal specimens would be of considerable benefit. The fluorescence ...

Circulating tumor cells (CTCs) are associated with poor survival in metastatic cancer. Their identification, phenotyping, and genotyping could lead to a better understanding of tumor heterogeneity and thus facilitate the selection of patients for personalized treatment. However, this is hampered because of the rarity of CTCs. We present an innovative approach for sampling a high volume of the p...

Multiplex protein quantification has been constrained by issues of assay specificity, sensitivity and throughput. This research presents a novel approach that overcomes these limitations using antibody-oligonucleotide conjugates for immuno-polymerase chain reaction (immuno-PCR) or proximity ligation, coupled with competitive PCR and MALDI-TOF mass spectrometry. Employing these combinations of t...

background : the ifa test is one of the most usual methods for detecting anti- toxoplasma antibod­ies, although it has not any unique standardization. it seems that the microscopic judg­ment of results is an important confounder in ifa test. therefore, we conducted the present study to clarify the role of microscopic observer, and other confounders on the test. methods: eighty sera were collect...

The base excision repair (BER) pathway plays a key role in protecting the genome from endogenous DNA damage. Current methods to measure BER activities are indirect and cumbersome. Here, we introduce a direct method to assay DNA excision repair that is suitable for automation and industrial use, based on the fluorescence quenching mechanism of molecular beacons. We designed a single-stranded DNA...

Aims: Breast and ovarian cancers are frequently associated with mutations in genes involved DNA double-strand break (DSB) repair by homologous recombination (HR). Risk factors for breast cancer often linked to estrogen-related pathways. Here, we studied the crosslink between estrogen HR pathway. Methods: We analyzed, using online annotation tolls, enrichment of candidate estrogen-upregulated am...
