Peter Horvath discusses image correction and machine learning methods for phenotypic discovery.

Development of a high-throughput screen utilizing a microfluidic device and a linearly growing yeast strain to simultaneously test the influence of various drugs on the replicative lifespan of yeast.

We developed FRET sensors that can detect 125 fluorophores simultaneously. From experimental analyses of over 1200 time-resolved fluorescence signatures on 300 prototypical sensors, we show that the optical responses are highly repeatable and minor variations between FRET networks can be discriminated resulting in a total of 10^375 unique responses in theory.

Settings for each cell type and virus can be saved and re-used to assure objective results. Additional information such as cell health, cell cycle status can be determined from the same plates using Nexcelom designed applications. Time course studies can be carried out by scanning plates over several days/weeks allowing for additional information than may be generated by carrying out end-point assays alone.

Development of valuable new tools for the immunologist, to resolve multiple antigens simultaneously with fluorescence microscopy: Brilliant Violet 421™, Alexa Fluor® 488, Alexa Fluor® 594 and Alexa Fluor® 647 conjugated monoclonal antibodies.

Sagittal, coronal and horizontal, one micron thick plastic (semithin) sections of adult zebrafish (Danio rerio) brain were photographed in 40X. The sections were then photomontaged together using in Adobe Photoshop CS5 Extended Version 12.0 to make the photographic atlas.

Molecular translocation of transcription factors from the cytoplasm to the nucleus is a pivotal event in many processes critical to cellular activation, diff erentiation and host defense. Existing methods used to measure nuclear translocation have significant limitations.
