Contractexpress combines scientific expertise with a gene-to-protein suite of automation and sample management products, which perform and track molecular biology and protein expression processes.
SeraFILE 10 is a subfractionation methodology for differential proteome analysis. Electrophoretic profiles of serum subfractions demonstrate good resolution and quantification. Carryover from the three highest abundance serum proteins, albumin, IgG and transferrin, is minimal.
Introduced in living E. coli cells, the SPP (Single Protein Production) System exploits the properties of MazF, a bacterial toxin that is an ssRNA- and ACA-specific endoribonuclease. Expression of this nuclease along with an engineered ACA-less target protein enables high signal to noise ratios.
Proteus protein analyzer system is based on Fourier transform infrared (FT-IR) technology and uses a Nicolet series FT-IR spectrometer to non-destructively scan protein samples for structural defect and impurity analysis, as well as process quality monitoring.
The 9800 Fast PCR System provides results in a standard 96-well plate in approximately 25 min.
ProAct Membrane Stain, for the detection of proteins on nitrocellulose or PVDF membranes, is as sensitive as Ponceau S and provides fast results. The ready-to-use stain confirms transfer prior to Western blotting.
Applied Biosystems has launched Power SYBR Green PCR Master Mix, a line of reagents for real-time PCR gene expression applications. SYBR Green dye binds to any double stranded DNA molecule, offering a flexible and easy to use labeling method for real-time PCR.
HiTrap Butyl-S FF (1 ml and 5 ml) prepacked columns (GE Healthcare) enable purification or removal of highly hydrophobic proteins.
The Genome Sequencer 20 System can produce more than 20 million raw bases per 5.5-hour run on a single instrument. The software included with the system enables mapping or de novo assembly for whole genome shotgun sequencing of genomes up to 50 megabases.
NeuroCult kits provide long-term expansion and efficient differentiation of human neural stem and progenitor cells.
HotStart-IT Taq DNA Polymerase uses a hot start method called primer-sequestration. Taq DNA Polymerase is combined with a recombinant protein that binds and sequesters primers at low temperatures, making them unavailable for use by Taq DNA Polymerase.
Waters Corporation ha announced three detectors specifically designed for use with their ACQUITY Ultra Performance LC (UPLC) System.
The FN1 microscope exhibits virtually no electrical noise and vibration-free operation, and provides maximum open space for working around a specimen or whole animal with easy access to manipulators, stimulators and flow chambers.
IOTest Anti-IRp60-PE monoclonal antibody is offered for the identification of an inhibitory protein present on NK and dendritic cells.
SureFIRE Conjugation Kits, comprised of preactivated enzymes and linkers, offer a reliable approach to labeling proteins or antibodies. The kits provide all necessary reagents for labeling proteins with either alkaline phosphatase (AP) or horseradish peroxidase (HRP).
