Ludesi this week launched Redfin Solo, its new 2D gel image-analysis software with a payment model that allows users to pay only for analyses they believe is of value to them.

According to the company, after analysis of a project, the software asks a user to review the results and pay only for those they want. The cost is $30 per gel.

In a statement, Ludesi CEO Ola Forsstrom-Olsson said that budgets are tight and research grants are limited for many researchers. Meanwhile, the need for powerful analytical tools is increasing. "We have succeeded in creating a tool that completely sidesteps this potential conflict," he said.


Thermo Fisher Scientific this week launched the Subcellular Protein Fractionation Kit for the separation and preparation of cytoplasmic, membrane, nuclear soluble, chromatin-bound, and cytoskeletal protein extracts from mammalian cultured cells or tissue for protein localization studies or enrichment of specific cellular compartments.

The kit includes four extraction buffers, a stabilized nuclease, and the Thermo Scientific Halt Protease Inhibitor Cocktail. According to the firm, the simple protocol is completed in less than three hours and requires no ultracentrifugation over gradients during any of the steps. The subcellular extracts obtained are compatible with a variety of downstream applications, including protein assays, Western blotting, electrophoretic mobility assays, and enzyme activity assays, the company said.
