Lentiviral Vectors with Dual Fluorescence/Luminescence Reporters

Abstract: The National Cancer Institute’s Protein Expression Laboratory seeks parties to co-develop dual luminescent/fluorescent cancer biomarkers. In research settings, visualization of tumors or tumor cells is often done using either bioluminescence or fluorescence. However, both of these methods have shortcomings: bioluminescence is not sensitive...

Enhanced Tissue Clearing Solution, Clearing-Enhanced 3D (Ce3D), Compatible with Advanced Fluorescence Microscopy Imaging

NIH immunologists have created a solution, Clearing-enhanced 3D (Ce3D), that can be used to make entire organs extremely transparent (top right panel). This allows the tissue to be imaged using advanced fluorescence microscopy techniques (bottom panel). Unlike current tissue clearing solutions, the Ce3D tissue clearing solution is robustly compatible...

Microscopy System for Distinguishing Stimulated Emissions as a Means of Increasing Signal

The invention pertains to a system and method for distinguishing stimulated emissions as a means of enhancing signal strength of fluorescent markers in fluorescence microscopy applications. The system is arranged such that an excitation beam (e.g., laser beam) illuminates a sample along some axis exciting the fluorescent markers used in the sample....

Simple, Field-Usable Fluorescence-Based Isothermal LAMP Assay for the On-Site Diagnosis of Malaria

CDC researchers have developed improved Loop-Mediated Isothermal Amplification (LAMP) assays for the nucleic acid-based diagnosis of malaria in field settings. The approach employs Plasmodium genus-specific LAMP primers and a portable tube scanner to run the LAMP reaction and measure fluorescence signal (e.g., SYBR green) as a measure of DNA amplification...

Total Emission Detection System for Multi-Photon Microscopy

Available for licensing and commercial development is a novel two-photon microscope system, which would allow improved fluorescent light collection, the use of less excitation power and deeper penetration of tissue and isolated cells. Multi-photon fluorescence microscopy (MPFM) is an imaging technique that can investigate biological processes to sub-cellular...

Fluorescent Nanodiamonds as Fiducial Markers for Microscopy

The invention relates to fluorescent nanodiamonds (FNDs) and their uses as fiducial markers for microscopy. FNDs are bright fluorescent probes that do not blink or bleach and have broad fluorescence excitation and emission peaks. The fluorescence intensity can be readily controlled by the size of the FND, the number of fluorescent centers produced...
