The TetraSpeck™ Fluorescent Microspheres Sampler Kit contains samples of the 0.1 μm, 0.5 μm, and 4.0 μm TetraSpeck™ beads. TetraSpeck™ beads 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.
Store in refrigerator 2°C to 8°C and protect from light.
Frequently asked questions (FAQs)
What are the excitation/emission peaks for TetraSpeck Microspheres?
The TetraSpeck Microspheres (Cat. Nos. T7279, T7280, T7281, T7283, T7284, T14792) are stained throughout with four different fluorescent dyes, yielding beads that each display four well-separated excitation/emission peaks at 360/430 nm (blue), 505/515 nm (green), 560/580 nm (orange) and 660/680 nm (dark red).

The cohesion protein ORD is required for homologue bias during meiotic recombination.
Authors:Webber HA, Howard L, Bickel SE
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 ... More
Exocytosis of IgG as mediated by the receptor, FcRn: an analysis at the single-molecule level.
Authors:Ober RJ, Martinez C, Lai X, Zhou J, Ward ES
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 ... More
Practical confocal microscopy and the evaluation of system performance.
Authors:Zucker RM, Price OT
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 ... More
Authors:Puri N, Kruhlak MJ, Whiteheart SW, Roche PA
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 ... More
Cytogenetic evidence for asexual evolution of bdelloid rotifers.
Authors:Mark Welch JL, Mark Welch DB, Meselson M
Journal:Proc Natl Acad Sci U S A
PubMed ID:14747655
DNA sequencing has shown individual bdelloid rotifer genomes to contain two or more diverged copies of every gene examined and has revealed no closely similar copies. These and other findings are consistent with long-term asexual evolution of bdelloids. It is not entirely ruled out, however, that bdelloid genomes consist of ... More
