by Mark Terry Researchers identified a relationship between the inverse expression of pRb2/p130 and vascular endothelial growth factor (VEGF) and tumor aggressiveness. Together, they may act as a biomarker for hepatocarcinoma (HCC) or liver cancer.
The Corning® 500 cm 2 Square DW Spillguard Cell Culture Dish is offered for culturing large numbers of anchorage dependent cells. Spillguard multilayer film protects against media spills and contamination during handling and transport to the incubator.
FiberCell® Systems Duet hollow fiber modules are offered for cell culture scale-up for antibody and recombinant protein production.
by Elizabeth Tolchin With so much genetic expression data being produced by microarrays in the study of cancer, knowing the extent to which these studies agree can provide valuable insight. That is just what researchers from Johns Hopkins University, Baltimore, set out to find.
Rapid Fractionation Of Complex Protein Extracts With Centrifugal MembraneAdsorber Units Improves Detection Of Proteins In 2d PageMay 19, 2004 10:51 am | Articles | Comments
Two-dimensional gel electrophoresis followed by mass spectrometry for protein identification is a reliable and reproducible means of sample analysis. A key element in this process is reducing sample complexity, as samples often consist of tens of thousands of proteins in a magnitude of different concentrations.
by Elizabeth Tolchin In a notice issued this week, the US Food and Drug Administration (FDA) announced a new guidance to encourage the development of fixed dose combinations (FDC) and copackaged products for the treatment of HIV infection and AIDS.
The fully automated TekBench liquid handling system for cell-based assays includes ELISA, ADME/TOX, Plasmid Prep, and RNA/DNA Isolation.
The high-capacity, variable-speed Rotating Mixer mixes 50 0.5-mL and 48 1.5-mL centrifuge tubes with snap-on or screw-down caps in an end-over-end motion at speeds varying from 4 to 40 rpm.
The 323 pump provides high-precision pumping in pharmaceutical and biotechnological processes. It is ideal for lab and benchtop applications such as metering or dosing of pharmaceutical products, live cell cultures, nutrients, or bioreactor constituents.
DRYFAST ULTRA® chemical duty diaphragm pumps (models 2021 and 2031) are ideal for tight spaces and budgets. PTFE (fluorinated plastics) is featured on all wetted surfaces to handle acids, bases, and other aggressive vapors. High-flow (22 to 32 Lpm) and deep vacuum (29.
MiniVap 96-well microplate sample evaporator units take just minutes to dry down a plate, replacing traditional techniques that typically take hours for solvent removal. Installation requires connection to a gas supply and standard mains socket.
The Universal 32/32R benchtop centrifuge utilizes one of the widest arrays of rotor selections and processes a variety of tubes from microliter tubes to 100-mL bottles to microtiter plates.
The CryogenicShipper-DG model safely transports diagnostic specimens, while the CryogenicShipper-DS model ships infectious substances. The cryogenic shippers store and transport specimens and dangerous goods at or below ?°150 C for up to 16 days, depending on conditions.
The TurboMix attachment mixers permanently mounts to most existing Vortex-Genie® 2/2T mixers to provide vigorous mixing of up to twelve 1.5- or 2.0-mL microtubes through a combination of vortexing and impact collision.
To authenticate QM efficiency and effectiveness in laboratory environments, the XP precision balance meets lab needs for high-resolution performance. With built in, comprehensive applications, the balance controls calibration, testing, and optimization.
