说明

一般說明

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.

應用

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.

外觀

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

儲存和穩定性

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.

分析報告

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.
