pSilencer 4.1-CMV: Versatile Vectors for Expression of siRNA, miRNA, and mRNA

4.1-CMV plasmid vectors are designed for long-term gene silencing experiments in a broad range of cell lines. The vectors carry an RNA polymerase II-type CMV promoter (human cytomegalovirus immediate-early promoter) and an optimized SV40...

The measurement of DNA condensation and mitochondrial changes during apoptosis and necrosis in cell based assays

Apoptosis represents a gene-directed, morphologically and biochemically distinct form of programmed cell death. Inappropriate control of apoptosis is associated with a variety of disease states such as cancer, AIDS, neurode...

Self-Drying Vacuum Pumps... the solution for applications producing condensation

Where gases with high moisture content must be evacuated during vacuum drying operations, condensate may collect in the vacuum pump head. Consequently, the pump may not perform properly and may take more time to evacuate the designated volume. New, self-drying pumps...

Immunoassay of Theophylline by fluorescence polarisation

Fluorescence immunoassay is applied to the detection of theophylline, a drug used for myocardial stimulation. Interference from other sample components is limited by use of polarization measurements, which discriminate between bound and unbound fluorophores. The detection system includes a T-format sampling module mounting two emissio...

ANALYSIS OF AMINO ACIDS BY REVERSED PHASE CHROMATOGRAPHY WITH PRECOLUMN DERIVATISATION AND UV/VISIBLE DETECTION

Amino Acids, RP-HPLC, Precolumn derivatisation, o-Phthalaldehyde (OPA), 2-Mercaptopropionic acid, Ultraviolet detection. Introduction: Underivatised amino acids do not significantly absorb light in the UV/visible spectrum. In order to increase sensitivity, their analysis normally includes a derivatisation step in whic...

Scaling-Up from Spinners, T-Flasks & Shakers: A versatile bioreactor for mammalian and microbial cells

Scaling up from spinners, T-flasks or shakers to a bioreactor system enables the researcher to reap the benefits of saving time.As an example of the typical savings one could expect, a single 5-L bioreactor has been shown to produce the equivalentamount of hybrid...

Cell-phone satisfaction stays low, says Consumer Reports

Less than half of cell-phone users really like the service they are getting, a Consumer Reports survey shows. The survey asked 50,000 people to recount experiences with static, "dead" zones, dropped calls and more, and ended up finding that cell-phone service is one of the lowest-ranked services nationwide in consumer's minds. And to top it off, almost a third of cell-phone users are ser...
