商品介绍
Species: Mouse
Host Species: E. coli
MW: 18 kDa
Genbank #: P01582
a.a: 115–270
Background:
Monocytes are the main source of secreted IL-1. They express predominantly IL-1beta while human keratinocytes express large amounts of IL-1alpha. Murine macrophages display a transition from IL-1beta to IL-1alpha production during maturation of monocytes into inflammatory macrophages.There are two functionally almost equivalent forms of IL-1, IL-1alpha and IL-1beta that are encoded by two different genes. IL1-beta is the predominant form in humans while it is IL-1alpha in mice. Both forms of IL-1 bind to the same receptor and therefore also show similar if not identical biological activities. The IL-1beta but not the IL-1alpha precursor must be processed before it can bind to the receptor. Both forms of IL-1 bind to the same receptor and therefore also show similar if not identical biological activities. The receptor isolated from T-cells is expressed predominantly on T-cells and cells of mesenchymal origin. It binds both types of IL-1 with equal affinity. This type is called also Type 1 receptor. It has been designated CD121a. The Type 2 receptor has been designated CD121b. It is isolated from B-cells, granulocytes, and macrophages. It is expressed predominantly on B-cells and cells of the myelomonocytic lineage and is encoded by a separate gene.
Description:
Recombinant IL-1a is a disulfide-linked monomer protein consisting of 157 amino acid residues and migrates as an approximately 18 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding murine Interleukin-1 alpha mature chain was expressed in E. coli.
UniProt
P01582
Synonym(s):
IL-1A, IL-1alpha, Interleukin-1 alpha, Hematopoietin-1
Purity:
≥95% by SDS-PAGE and HPLC
Endotoxin Level:
<0.1 ng/µg (1 EU/µg), using the LAL gel clot method.
Biological Activity:
The ED50 was determined by a cell proliferation assay using the murine helper T cell line, D10.G4. to be 10.0 pg/ml.
Formulation:
Lyophilized from 0.2 µm filtered PBS.
Format:
lyophilized protein
Reconstitution:
Reconstitute at 0.1-1.0 mg/ml in distilled water. This solution can then be diluted into other buffers. To maximize product collection from vial surface, vortex briefly and then spin down to recollect the liquid.
Storage / Stability:
The lyophilized protein is stable for at least 2 years from date of receipt when stored at -20°C. Upon reconstitution, store in working aliquots at +4°C for up to one month, or at -20°C for up to six months, in the presence of a carrier protein. Avoid repeated freeze/thaw cycles.
