Sigma-Aldrich last week launched the PhosDecor Fluorescent Phosphoprotein In-Gel Detection Kit for identifying phosphorylated proteins. The kit includes a phosphate specific PhosDecor Stain, specially formulated buffers, and a positive control to validate system performance.
 

 
Olink Bioscience this week released the Duolink reagent kit for the detection of single molecule events such as protein interactions in unmodified cells and tissue sections. Duolink is based on the company’s proprietary in situ Proximity Ligation Assay technology. The kits are available for use with any combination of two primary antibodies raised in mouse, rabbit, or goat.
 

 
Invitrogen launched the Dynabeads M-270 Immunoassay this week. The beads are used to immobilize antigens such as proteins and peptides for in vitro diagnostic magnetic bead-based immunoassay applications. The hydrophilic surface of the beads “ensures low non-specific binding of serum proteins that would otherwise interfere with the assay,” the company said in a statement, adding they disperse well, are easily handled in a variety of buffers, and do not inhibit enzymatic activity.
 

 
AnaSpec this week released a new line of SensoLyte Anti-MOG ELISA kits, which the company said is the industry’s first anti-MOG ELISA kits. AnaSpec also added 72 antibodies to its collection of catalog antibodies. They include Anti-Chromogranin A; Anti-p19INK4d, and Anti-Protein Kinase C.
