Category: Receptors$151.00 – $506.00
Description
Accession
NP_004624
Source
DNA sequence encoding Human IL-1R2/IL-1 RII/CD121b including a C-hFc tag was expressed in HEK293 Cells.
Molecular weight
Recombinant Human IL-1R2/IL-1 RII/CD121b is a protein consisting of amino acid residues [Phe14-Glu343] ,The protein has a predicted MW of 64.4 kDa. Due to glycosylation, the protein migrates to 70-80 kDa based on Tris-Bis PAGE result..
Purity
>95%, as determined by SDS-PAGE and HPLC
Biological Activity
see methods section
Endotoxin
Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).
