Cell Culture Chambers

The new lumox x-well cell culture chambers are available with a 50 µm ultrathin, gas-permeable film base that combines excellent imaging with superior cell growth. Compared to plastic or glass bases, the gas-permeable lumox film provides more effective gas exchange and homogeneous cell growth. Lumox film shows virtually no autofluorescence and higher light transmission for consistently high assay sensitivity and excellent microscopy and fluorescence-based imaging. Lumox film is chemically resistant to a multitude of fixatives and stains and can be easily cut for cell isolation or storage after fixation and staining. Lumox x-well cell culture chambers are available in 1-, 2-, 4-, and 8-well configurations with a standard adherent cell culture surface. Chambers can be detached from the slide frames easily without tools or adhesive residues. The culture chamber slides are conveniently sold per sterile tray of six.

Chiral Column

The Amylose-1 chiral stationary phase has been added to the high-efficiency Lux polysaccharide chiral column line. The affordable Amylose-1 adds valuable enantioselectivity to the Lux column family with the chiral selector amylose tris (3,5-dimethylphenylcarbamate) and is a guaranteed alternative to other phases with the same chiral selector. Offered in 5-µm particles, the new media is available in analytical columns and Phenomenex-patented Axia preparative column hardware, both of which are stable in normal phase, reversed phase, polar organic, and supercritical fluid (SFC) conditions. The Phenomenex Axia preparative format delivers longer column lifetime, higher efficiencies, improved performance, and high reproducibility, compared with conventionally packed columns for lab-scale preparative high-performance liquid chromatography (HPLC) and SFC chromatography. The expanded Phenomenex Lux chiral column line of six amylose and cellulose chiral selectors comprises an affordable and complementary kit for chiral separations, featuring high efficiency, excellent loading capacity, and pressure stability up to 300 bar in a wide range of conditions.

PCR Kits

My PCR Kits contain all the necessary components for polymerase chain reaction (PCR) and are designed for convenient use. The kits come in three packs with different combinations of reagents. My PCR Kit 1 contains 2X Taq master mix with Taq DNA polymerase, deoxynucleotide triphosphates (dNTPs), MgCl2, 50mM MgCl2,  6X loading dye, nuclease-free water, and buffer. My PCR Kit 2 offers Chromo Taq DNA polymerase, 2mM dNTPs mix, 50mM MgCl2, and buffers. Finally, My PCR Kit 3 is a standard pack offering great value and convenience with Taq DNA polymerase, 2mM dNTPs mix, 6X loading dye, 50mM MgCl2, and buffers. All Vivantis products derive from in-house research to provide integrated solutions to life science researchers worldwide.

Neuron Cryopreservation Kit

The NeuroFreeze kit utilizes a unique, straightforward, and effective method for cryopreserving primary neurons from mice and rats. Neurons frozen in this cutting-edge media can be stored for 12 months and will retain up to 90% viability upon thawing. NeuroFreeze has an easy-to-follow freezing procedure that does not require multiple stepwise reductions in temperature. Thawed neurons show all the expected characteristics of primary neurons, including appropriate morphology and expression of neuronal and synaptic markers. The NeuroFreeze kit is advantageous for researchers using rodent models of disease or genetically engineered strains. The availability of this media will enable investigators to freeze primary neurons and thaw them as necessary, without having to harvest neuronal cells for each investigation. Researchers with the means to conduct studies on neurons from the same cellular source and origin will have more consistent results and decrease the need for repeated experiments.

Mounting System

McPherson introduces a new line of mechanical positioning systems with high load capacity and stiffness. This strut-based mounting system minimizes vibration and allows easy and precise position adjustment of a wide variety of hardware. It can even work inside high vacuum or ultrahigh vacuum (UHV) systems. The six struts provide very solid (seismically adequate) support. When submillimeter alignment is required, the six-strut system is a proven way of rigidly supporting instruments and fixtures with precise adjustability. Even the smallest designs support 200 lbs. The strut mechanical positioner has up to six degrees of freedom—translational: X, Y, Z; and angular: pitch, roll, and yaw. It consists of a support system made up of adjustable struts and provides support without adding stress or distortion. The struts have ball joint ends and an orthogonal arrangement to simplify position adjustments. The result is a strong, rigid system that allows easy positioning of even heavy equipment in all six degrees of freedom.
