Vivascience has released the Vivapure Anti-Has Kit for human albumin depletion. The kit is based on anti-HAS antibody fragments coupled to cross-linked agarose for removal of 95 percent of albumin from a human sample without binding other proteins, according to the company. The kit can also remove 50 to 80 percent of rat and mouse albumin. The kit includes affinity-resin, centrifugal columns that can be filled with the amount of resin desired, micro-centrifuge tubes, and binding buffer for processing 12 serum samples.


BD Biosciences Clontech has released the BD Universal His Tag Western Blot Kit for detection of any histidine-tagged protein without antibodies. The detection reagent is derived from the BD Talon resin technology. The kit allows the user to detect as little as 1 ng of purified protein, according to the company.


FFE Weber of Planegg, Germany has announced the development of its ProMetheus Free Flow Electrophoresis system.
