Analysis Note

The DTT-reduced protein migrates as a 48 kDa polypeptide on SDS-PAGE due to glycosylation. The non-reduced protein migrates as a 46 kDa polypeptide on SDS-PAGE due to internal cystines.

Application

B18R, Human RecombinantCarrier-Free has been used as a decoy receptor to study the intrinsic antiviralactivity of recombinant soluble IFNα/β cell surface receptor 2 (sIFNAR2). Ithas also been used in the generation and maintenance of induced pluripotentstem cells (iPSCs) and human IPSCs.

Disclaimer

Unless otherwise stated in our catalog or other company documentation accompanying the product(s), our products are intended for research use only and are not to be used for any other purpose, which includes but is not limited to, unauthorized commercial uses, in vitro diagnostic uses, ex vivo or in vivo therapeutic uses or any type of consumption or application to humans or animals.

General description

Product Source: Insect cells infected with baculovirus: amino acids His20-Glu 351 with a His-tag attached of Vaccinia Virus B18R.
Research area: Immuno and CKS 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.

Physical form

Sterile liquid;10 mM phosphate, 0.5 M NaCl, pH 7.5 buffer and is filtered with a 0.2µm filter before vialing.

Preparation Note

For best recovery, quick-spin vial prior to opening. Thaw on ice. While on ice, aliquot B18R protein into sterile, nuclease-free, low protein-binding eppendorf tubes and store at -80°C. Limit repeated freeze and thaw cycle. Use in a sterile environment.
Further dilutions should be made into appropriate buffer or medium.
