DeePlexing – Extending Imaging Multiplexity Using Machine Learning

Spatial proteomics and transcriptomics are fast-emerging fields with the potential to revolutionize various branches of biology. In the last five years, various multiplex immunofluorescence and immunohistochemistry imaging methods have been developed to stain 5-60 different protein markers in a given tissue. Nonetheless, most of these techniques are iterative and can image a maximum of 3-8 markers in a single cycle, resulting in processing time of several hours to days.

Fluorescence Scanning System for Improvement of Analytical Ultracentrifugation

This technology includes improvements in the fluorescence scanner to increase efficiency. This method works by eliminating the need to radially slide the optical assembly during scanning, instead using a galvanometric mirror deflecting a laser beam to different positions in the sample. This allows the scanner to be incorporated into existing commercial analytical ultracentrifugation (AUC) systems with minimal modifications.

Apparatus for Cryogenic-Electron Microscopy Sample Preparation

Cryo-Electron Microscopy (cryo-EM) is used to obtain high-resolution structural images of macromolecular structures. Samples must be purified and loaded onto cryo-EM grids before imaging. The ideal cryo-EM grid consists of particles that are evenly and richly distributed in a broad distribution of orientations throughout the holes of the support film. Current techniques to prepare cryo-EM grids are performed manually and require trial and error, resulting in a bottleneck in cryo-EM workflows.

Methods for near real-time aerosol chemical analysis for environmental and occupational monitoring

­Exposures to hazardous airborne particles can pose a significant health risk to those routinely exposed in ambient air and industrial work environments. Measuring chemical composition and concentration of aerosol particles is important to preventing worker exposures and protecting health.

High-Throughput Assay for Detection and Monitoring of Endocrine Disrupting Chemicals in Water Sources

There is growing awareness that a wide variety of synthetic and natural compounds that may be present in water sources, such as streams, wells, and ground water, may lead to adverse health effects, including increased cancer risk. Even low concentrations of these compounds are of concern, as they may have biological effects at concentrations of parts per billion or less.

Humanized Mouse Model to Study Mesothelin (MSLN) -targeted Cancer Therapeutics: Bl6/TPO Mice

Mesothelin (MSLN) is an antigen highly expressed in several human cancers including mesotheliomas, ovarian cancers and pancreatic cancers. As such, human MSLN (hMSLN) is a target for many anti-cancer drugs. Most therapeutics targeting hMSLN do not recognize the mouse isoform of MSLN (mMSLN) and therefore cannot be tested in mouse cancer models. 

Software for Modeling Delivery and Penetration of Antibody Conjugates

The National Cancer Institute (NCI) seeks parties to license software for modeling the targeted delivery of anti-cancer agents in solid tumors.

The software models the permeability and concentration of intravenously administered antibody anti-cancer agent conjugates in solid tumors.  The models can be used to determine optimal dosing regimen of a therapeutic in a particular cancer type.  Thirty factors that affect delivery rates and efficiencies are analyzed as variables in generating the models.

Tni-FNL: An Improved Trichoplusia Ni Cell Line for Protein Expression

Researchers at the National Cancer Institute (NCI) have developed an improved insect cell line, Tni-FNL, derived from the cabbage looper, Trichoplusia ni.  The Tni-FNL cell line is capable of high level expression of heterologous proteins using baculovirus-based expression systems.  When compared to commercially available cell lines used for the same purpose, the Tni-FNL cell line often outperforms those for protein expression.  These cells have a high growth rate and are capable of growth at a lower temperature.

New Insect Sf9-ET Cell Line for Determining Baculovirus Titers

The baculovirus-based protein expression system has gained increased prominence as a method for expressing recombinant proteins that are used in a wide range of biomedical applications. An important step in the use of this system is the ability to determine the virus infectious titer, i.e., the number of active baculovirus particles produced during an infection of the insect host cell.
