Extrapancreatic autoantibody profiles in type I diabetes.

Type I diabetes (T1D) is an autoimmune disease characterized by destruction of insulin-producing β-cells in the pancreas. Although several islet cell autoantigens are known, the breadth and spectrum of autoantibody targets has not been fully explored. Here the luciferase immunoprecipitation systems (LIPS) antibody profiling technology was used to study islet and other organ-specific autoantibody responses in parallel.

Antibody profiling of Borrelia burgdorferi infection in horses.

Infection with Borrelia burgdorferi is common in horses and ponies from the New England and mid-Atlantic regions of the United States. Here, we evaluated luciferase immunoprecipitation systems (LIPS) for profiling antibody responses against three different antigenic targets for the diagnosis of equine B. burgdorferi infection.

Searching for biomarkers: humoral response profiling with luciferase immunoprecipitation systems.

B-cell-mediated humoral responses are triggered in many human diseases, including autoimmune diseases, cancer, and neurologic and infectious diseases. However, the full exploitation of the information contained within a patient's antibody repertoire for diagnosis, monitoring and even disease prediction has been limited due to the poor diagnostic performance of many immunoassay formats. We have developed luciferase immunoprecipitation systems (LIPS) that harnesses light-emitting proteins to generate high-definition antibody profiles that are optimal for both diagnostics and biomarker discovery.

Emerging tactical strategies for fighting the war on cancer based on the genetic landscape.

Although it is well-established that cancer is driven by genetic mutations resulting in the acquisition of onco-genes and the loss of tumor suppressors, until recently many of the genomic details remained obscure. As a result of recent high-throughput DNA sequencing, basic insights into the spectrum of protein coding mutations in many cancers are now known. These findings provide an unprecedented framework of understanding and present new avenues for diagnosis, treatment, and prevention of cancer.

LIPS arrays for simultaneous detection of antibodies against partial and whole proteomes of HCV, HIV and EBV.

For many infectious agents, the detection of antibodies is critical for diagnosing, monitoring and understanding vaccine responses. To facilitate the highly quantitative and simultaneous analysis of antibodies against multiple proteins from infectious agents, we have developed Luciferase Immunoprecipitation Systems (LIPS) arrays. By configuring microtiter plates with multiple antigens and testing control and infected serum samples at one time in solution, LIPS arrays provided highly reproducible antibody titers to panels of antigens with a wide dynamic range of detection.
