Qiagen, Amersham

Premium

Qiagen this week released its EasyXpress Protein Synthesis System, which produces a recombinant protein from a gene in one day. Scientists can generate expression templates using the EasyXpress Linear Template Kit, and then produce high protein yields in E coli using EasyXpress Protein Synthesis kits. Proteins with affinity tags can be recovered using Ni-NTA or Strep-Tactin matrices.


Amersham Biosciences recently launched three new products. The first, released last week, was its LabMate PD-10 Buffer Reservoir, a reservoir for its PD-10 disposable desalting columns. The reservoir allows for easier equilibration of the column.
The second product, released early this week, was its Deep Purple Protein Stain, a fluorescent stain which allows scientists to detect and quantify proteins in 1D and 2D gels more accurately and at greater quantities. According to a statement from Amersham, the stain offers up to eight times more sensitivity in protein detection and eliminates the problem of background “speckling.” The stain is compatible with Amersham’s Typhoon imager as well as other industry standard fluorescent scanners. According to Amersham, the stain is “the most sensitive in-gel fluorescent total protein stain commercially available,” and is sold for 30 percent less cost “than the other products on the market.”
The last product was ImageQuant TL software for image analysis of 1D gels, 2D gels, dot blots, slot blots, microplates, TLC, macroarray and plaque assays. ImageQuant can be used either alone or with the Amersham imager Typhoon scanner. ImageQuant was developed as part of a deal with Nonlinear Dynamics (see PM 7-25-03).
