Rapid CE microbial assays for consumer products that contain active bacteria

Rapid electrochemiluminescence assays of polymerase chain reaction products.

We demonstrate the first use of an electrochemiluminescent (ECL) label, [4-(N-succimidyloxycarbonylpropyl)-4'-methyl-2,2'- bipyridine]ruthenium(II) dihexafluorophosphate (Origen label; IGEN Inc.), in DNA probe assays. This label allows rapid (less than 25 min) quantification and detection of polymerase chain reaction (PCR)-amplified products from oncogenes, viruses, and cloned genes. For the PC...

Introducing new products that affect consumer privacy: A mediation model

Many innovative products can only fully deploy their value if they rely on consumers’ personal information. This issue challenges the confidence consumers have in new innovations, and revolutionizes marketing practices. Malhotra, Kim, and Agarwal’s (2004) framework provides the theoretical basis for hypotheses on the consequences of privacy concerns. An empirical study in the context of four pe...

Common Commercial and Consumer Products Contain Activators of the Aryl Hydrocarbon (Dioxin) Receptor

Activation of the Ah receptor (AhR) by halogenated aromatic hydrocarbons (HAHs), such as 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD, dioxin), can produce a wide variety of toxic and biological effects. While recent studies have shown that the AhR can bind and be activated by structurally diverse chemicals, how widespread of these AhR agonists are in environmental, biological and synthetic materi...

Improved electrochemiluminescent label for DNA probe assays: rapid quantitative assays of HIV-1 polymerase chain reaction products.

We describe the characterization and utility of a new electrochemiluminescent (ECL) label for oligonucleotides, utilizing phosphoramidite chemistry. This phosphoramidite of the tris(2,2-bipyridine)ruthenium(II) complex, bis(2,2-bipyridine)(4-[4-(2-cyanoethoxy-N,N-diisopropyl-amino) phosphinoxybutyl]4'-methyl)2,2-bipyridine ruthenium(II) dihexafluorophosphate or Origen phosphoramidite, enables t...
