IL1R2 Protein (C-Term, Extracellular Domain)

Catalog No. ABIN1684616

Product Details

Target: IL1R2 (Interleukin 1 Receptor, Type II (IL1R2))

Protein Type: Recombinant

Biological Activity: Active

Protein Characteristics: C-Term, Extracellular Domain

Origin: Human

Source: HEK-293T Cells

Specificity: Optimized DNA sequence encoding Human extracellular domain of human IL-1 receptor type II including a C-terminal His tag was expressed in HEK293 cells.

Characteristics: Recombinant IL-R2 (CD121b) is a protein consisting of 342 amino acid residue subunits, due to glycosylation migrates as an approximately 50-60 kDa protein on SDS-PAGE.

Purity: > 97 %, as determined by SDS-PAGE and HPLC

Sterility: 0.2 μm filtered

Endotoxin Level: Endotoxin content was assayed using a LAL gel clot method. Endotoxin level was found to be less than 0.1 ng/µg(1EU/µg).

Application Details

Comment:

Recombinant Human IL-1 receptor type activity was measured by its ability to inhibit IL-1b dependent proliferation in mouse helper T cells. The ED50 for this effect is typically 5 µg/mL in the presence of 40 pg/mL of human IL-1b.

Restrictions: For Research Use only

Handling

Format: Lyophilized

Background: IL-6 is produced by many different cell types. The main sources in vivo are stimulated monocytes, fibroblasts, and endothelial cells. Macrophages, T-cells and B-lymphocytes, granulocytes, smooth muscle cells, eosinophils, chondrocytes, osteoblasts, mast cells, glial cells, and keratinocytes also produce IL6 after stimulation. IL6 is a member of a family of cytokines, which also includes LIF, CNTF, Oncostatin M, IL11, and CT-1. All known members of the IL6 cytokine family induce hepatic expression of acute phase proteins. The IL6 receptor is expressed on T-cells, mitogen-activated B-cells, peripheral monocytes and some macrophage- and B-cell derived tumor cell types. It is not expressed in resting B-cells but in resting T-cells. The IL6 receptor is a strongly glycosylated protein of 80 kDa and a length of 449 amino acids. It has been designated CD126.
