BACKGROUND We report the first-in-human safety and immunogenicity assessment of a prototype Ad26 vector-based human immunodeficiency virus (HIV) vaccine in humans. METHODS Sixty Ad26-seronegative, healthy, HIV-uninfected subjects were enrolled in a randomized, double-blinded, placebo-controlled, dose-escalation phase 1 study. Five groups of 12 subjects received 10(9)-10(11) vp of the Ad26-Env...

Lipoprotein(a) [Lp(a)] has been measured in numerous clinical and epidemiological studies by a variety of immunochemical methods. However, little, if any, consideration has been given to the confounding effect of the size heterogeneity of apolipoprotein(a) [apo(a)] on the measurement of Lp(a). We developed three direct-binding enzyme-linked immunosorbent assays (ELISAs) with detecting antibodie...

An enzyme-linked immunosorbent assay (ELISA) was developed for detecting antibodies against Trypanosoma cruzi. Two synthetic T. cruzi peptides, TcD and PEP2, were used. The specificity and sensitivity of the peptide ELISA were determined with 260 serum samples from individuals living in an area in which Chagas' disease is endemic. ELISAs were performed with the peptides singly or in combination...

The Merck pneumococcal (Pn) enzyme-linked immunosorbent assays (ELISAs) for measuring antibodies to 12 serotypes (serotypes 1, 3, 4, 6B, 7F, 8, 9V, 12F, 14, 18C, 19F, and 23F) were validated in 1999. Merck Laboratories developed the Pn assays using 10 microg/ml C polysaccharide, 100 microg/ml Pn polysaccharide (PnPs) 25, and 100 microg/ml PnPs 72 for preadsorption of samples, standards, and con...
