TNFRSF1A-1908H
Optional Service: Optional requirements on this protein
Product Overview :
Recombinant Human Tumor Necrosis Factor Receptor Inhibitor produced inNSOis a disulfide linked homodimer, glycosylated, polypeptide chain. rHusTNFRI/Fc chimera (sTNFRI/Fc chimera) was fused to carboxy-terminal 6X his-tagged Fc part of human IgG1, via a linker peptide.
Description :
Tumor necrosis factor receptor superfamily, member 1A, (TNFRI) also known as TNFRSF1A or CD120A is the principal receptor through which many of the pro-inflammatory activities of TNF-alpha are mediated. TNFRI contains a death domain through which it interacts with other death-domain proteins to promote cellular responses. It regulates immune and inflammatory responses.
Source :
Mammalian cells
Amino Acid Sequence :
The sequence of the first five N-terminal amino acids was determined and was found to be Met-Glu-Glu-Val-Ser.
Molecular Weight :
The predicted molecular weight of Recombinant Human TNF sRI is Mr 48 kDa. However, the actual molecular weight as observed by migration on SDS Page is Mr 55-60 kDa.
Form :
Purified.
Purity :
Greater than 95.0% as determined by: (a) Analysis by RP-HPLC. (b) Anion-exchange FPLC. (c) Analysis by reducing and non-reducing SDS-PAGE Silver-Stained gel.
Dimers & Aggregates :
Less than 1% as determined by silver-stained SDS-PAGE gel analysis.
Endotoxin :
Less than 0.1 ng/µg (IEU/µg) of rHusTNFRI.
Protein Content :
Protein quantitation was carried out by two independent methods: 1) UV spectroscopy at 280 nm. 2) Analysis by RP-HPLC, using a standard solution of rHusTNFRI as a Reference Standard.
Biological Activity :
rHusTNFRI is fully biologically active when compared to standards.The activity was measured by its ability to neutralize apoptosis of mouse L929 cells treated with 0.25 ng/mL rhTNF-a. The ED50 for this effect is typically 0.4-1 ng/mL.
Storage :
-20°C (aliquot), avoid repeated freeze and thaw cycles.
