Targeted Metabolomics on Rare Primary Cells

Here, we present a protocol to accurately and reliably measure metabolites in rare cell types. Technical improvements, including a modified sheath fluid for cell sorting and the generation of relevant blank samples, enable a comprehensive quantification of metabolites with an input of only 5000 cells per sample.

Quantitative Measurement of Relative Retinoic Acid Levels in E8.5 Embryos and Neurosphere Cultures Using the F9 RARE-Lacz Cell-based Reporter Assay09:49

Quantitative Measurement of Relative Retinoic Acid Levels in E8.5 Embryos and Neurosphere Cultures Using the F9 RARE-Lacz Cell-based Reporter Assay

Methods to accurately measure retinoic acid (RA) levels in small amounts of tissue do not exist. This protocol describes the easy, quantitative measurement of relative RA levels in E8.5 embryos and neurospheres using an RA reporter cell line.

Coculture System with an Organotypic Brain Slice and 3D Spheroid of Carcinoma Cells

The organotypic brain slice coculture with carcinoma cells enables visualizing morphological changes by fluorescence as well as bright field (video) microscopy during the process of carcinoma cell invasion of brain tissue. This model system also allows for cell exchange and replenishment approaches and offers a wide variety of manipulations and...

Enrich and Expand Rare Antigen-specific T Cells with Magnetic Nanoparticles09:28

Enrich and Expand Rare Antigen-specific T Cells with Magnetic Nanoparticles

Antigen-specific T cells are difficult to characterize or utilize in therapies due to their extremely low frequency. Herein, we provide a protocol to develop a magnetic particle which can bind to antigen-specific T cells to enrich these cells and then to expand them several hundred-fold for both characterization and therapy.
