Cell Imaging > Cell Migration

Cell migration, the movement of cells from one location to another, is a critical component of both normal and abnormal biological processes. The migration of fluorescently labeled cells from one area of a microplate well to another can be monitored using a cellular imaging system. Automated analysis software calculates the amount of cell migration in each well.

Cell Imaging > Cell Cycle Analysis

Transition of a cell through the cell cycle can be monitored using fluorescently labeled cell cycle proteins that are cyclically expressed and degraded. FUCCI technology is based on the overexpression the cell cycle-dependent proteins geminin and Cdt1, respectively fused to a green fluorophore and a red fluorophore. Cdt1 levels peak in G1 phase, so cells in G1 appear green; geminin levels rise in late S, G2 and M phase, so cells in these phases appear red.

Kinase/Phosphatase Assays

Kinases are one of the most critical targets in drug discovery today. These enzymes are key components in cellular signaling pathways, and disruption to their function causes a variety of diseases, such as metabolic diseases, certain cancers, and cardiac disease. The functionally related phosphatases and phosphodiesterases are also important screening targets.

Nanoparticles

Nanomaterials are typically less than 100 nm in diameter, small enough to penetrate mammalian cells. They can be synthesized in many shapes, such as rods, tubes, and particles, as well as in different materials. Targeting or therapeutic molecules can be readily attached to nanoparticles, and when these are delivered systemically, the targeting molecules enable detection of certain cell populations, such as tumor cells, while attached therapeutic compounds can act on the targeted cells.

AlphaScreen

AlphaScreen® Technology is a homogeneous, high-throughput method for detecting intramolecular binding. Donor and acceptor beads are attached to biomolecules, and when the beads are brought into proximity (via binding), a cascade of chemical reactions occurs, amplifying a signal that is detected on the SpectraMax® i3x and Paradigm® Multi-Mode Microplate Readers.
