The 0.5 μm TetraSpeck™ microspheres are stained throughout with four different fluorescent dyes, yielding beads that each display four well-separated excitation/emission peaks - 360/430 nm (blue), 505/515 nm (green), 560/580 nm (orange) and 660/680 nm (dark red). These microspheres can greatly facilitate the calibration of conventional fluorescence microscopes, confocal laser scanning microscopes, and associated image-processing equipment for both scientific and commercial imaging, especially for multicolor applications.

Abstract
The cohesion protein ORD is required for homologue bias during meiotic recombination.
Journal:J Cell Biol
PubMed ID:15007062
'During meiosis, sister chromatid cohesion is required for normal levels of homologous recombination, although how cohesion regulates exchange is not understood. Null mutations in orientation disruptor (ord) ablate arm and centromeric cohesion during Drosophila meiosis and severely reduce homologous crossovers in mutant oocytes. We show that ORD protein localizes along
Exocytosis of IgG as mediated by the receptor, FcRn: an analysis at the single-molecule level.
Journal:Proc Natl Acad Sci U S A
PubMed ID:15258288
'IgG transport within and across cells is essential for effective humoral immunity. Through a combination of biochemical and in vivo analyses, the MHC class I-related neonatal Fc receptor (FcRn) is known to play a central role in delivering IgGs within and across cells. However, little is known about the molecular
Practical confocal microscopy and the evaluation of system performance.
Journal:Methods
PubMed ID:10491274
'The laser scanning confocal microscope has enormous potential in many fields of biology. Currently there is a subjective nature in the assessment of a confocal microscope''s performance by primarily evaluating the system with a specific test slide provided by the user''s laboratory. To achieve better performance from the equipment, it
Mast cell degranulation requires N-ethylmaleimide-sensitive factor-mediated SNARE disassembly.
Journal:J Immunol
PubMed ID:14607937
'Mast cells possess specialized granules that, upon stimulation of surface FcR with IgE, fuse with the plasma membrane, thereby releasing inflammatory mediators. A family of membrane fusion proteins called SNAREs, which are present on both the granule and the plasma membrane, plays a role in the fusion of these granules
Visualizing spatiotemporal dynamics of multicellular cell-cycle progression.
Journal:Cell
PubMed ID:18267078
The cell-cycle transition from G1 to S phase has been difficult to visualize. We have harnessed antiphase oscillating proteins that mark cell-cycle transitions in order to develop genetically encoded fluorescent probes for this purpose. These probes effectively label individual G1 phase nuclei red and those in S/G2/M phases green. We
