EMD Biosciences, NUNC

Premium
EMD Biosciences has launched the ProteoPlex Human Angiogenesis Arrays. The ProteoPlex Arrays have spots of antibodies that detect eight to 12 different cytokines, the company said, and kits include standard concentrations of the cytokines.
 
EMD said customers need only 25 to 50 microliters of sample to measure the cytokines in about four hours. The antibody spots on the arrays are in quadruplicate allowing a researcher to do statistical analysis on the data, EMD said.

NUNC launched its ProPur protein purification kit. ProPur provides “protein purification from initial fractionation to final polishing steps in yields typically associated with a gravity drip column but with the speed of a spin column,” the company said.
 
The kits employ Protein G, Protein A or metal chelate resin chemistries and employ affinity chromatography.
