Effective treatment of ovarian cancer depends upon the early detection of the malignancy. Here, we report on the development of a new nanostructured immunosensor for early detection of cancer antigen 125 (CA-125). A gold electrode was modified with mercaptopropionic acid (MPA), and then consecutively conjugated with silica coated gold nanoparticles (AuNP@SiO2), CdSe quantum dots (QDs) and anti-...

OBJECTIVE To evaluate the correlation between Cancer Antigen-25 (CA-125) levels with the amount of ascites in patients with liver cirrhosis. STUDY DESIGN Observational, analytical study. PLACE AND DURATION OF STUDY Shifa International Hospital, Islamabad, from March 2012 to February 2013. METHODOLOGY A total of 130 patients with liver cirrhosis (with and without ascites) had serum CA-125 ...

The monoclonal antibody RB-8 heavily labels axons from the ventrolateral olfactory epithelium and their terminals in the glomeruli of the ventrolateral olfactory bulb, but leaves the axons from the dorsomedial epithelium unstained or lightly stained. RB-8 reacts with a 125 kDa membrane protein in both olfactory nerve and other parts of the CNS (Schwob and Gottlieb, 1986). Here we report further...

Radioautographic study of the binding of GAT-(125)I to spleen cells of genetic responder and nonresponder mice demonstrates that among mice not injected with antigen all strains have approximately the same number of antigen-binding cells; after injection with antigen the number of antigen-binding cells increases in responders but not in nonresponders. Nonresponders are shown to make antibody af...

Radioimmunoassays for detecting cell-associated or released virus are described using either (125)I- or [(3)H]acetate-labeled antibodies. In the first assay system, antigen-antibody complexes were separated from free antibody by centrifugation. Sensitivities of 0.1 mug of iridescent virus could be achieved with either (125)I- or [(3)H]acetate-labeled antibody. In the second assay, the antigen w...

Herpesvirus (GPHV) antigen is either present in very small amounts, or absent in leukemic lymphoblasts taken directly from strain 2 guinea pigs. However, after maintenance in tissue culture for 72 hr, almost 100% of these lymphoblasts contained GPHV antigen. The expression of GPHV antigen could be demonstrated by indirect immunofluorescent technique as well as by the direct (125)I labeled antib...
