Sigma-Aldrich announced this week the launch of its Panorama Human p53 Protein Functional Microarray. Developed by Procognia and distributed exclusively by Sigma-Aldrich, the p53 protein microarray contains wild type human p53 and 49 of its variants. Each variant contains a mutation or single nucleotide polymorphism that results in an amino acid change or a truncation. The array is based on a novel and proprietary technology that ensures the protein is correctly folded and confers full functionality, the company said.


Elchrom Scientific introduced this week its Blot-EX — a new non-acrylmaide, not-toxic, high resolution electrophoresis precast hydrogel that was designed to increase protein transfer efficiency during Western blotting.

According to the Cham, Switzerland-based company, Blot-EX offers overall recovery efficiency of up to 90 percent, which can be obtained in less than 10 minutes — a significantly reduced transfer time when compared to industry standard polyacrylamide pre-cast gels.
