      DescriptionB18R, Human Recombinant Carrier-Free
      Background InformationB18R is a virally-encoded protein that acts as a decoy receptor for Type 1 Interferons. B18R enables increased cell viability during RNA transfection protocols designed to convert human somatic donor cells into iPSCs via direct delivery of synthetic mRNA's. As a type I IFN receptor, B18R has a broad species specificity. It has high affinity for human IFN-alpha and also binds rabbit, bovine, rat, pig, and mouse IFN-alpha and IFN-beta.
      Product Information
      PresentationSterile liquid;10 mM phosphate, 0.5 M NaCl, pH 7.5 buffer and is filtered with a 0.2µm filter before vialing.
      Quality LevelMQ100
      ApplicationB18R protein can be used with the Simplicon® RNA Reprogramming Technology (Catalog No. SCR550) to create “foot-print” free human iPS cells at the highest efficiency without unwanted RNA degradation caused by cellular IFN responses.
