General description

B18R 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 Source: Insect cells infected with baculovirus: amino acids His20-Glu 351 with a His-tag attached of Vaccinia Virus B18R.
