Descrizione

Descrizione generale

The IL-2 receptor system consists of three non-covalently linked subunits termed IL-2Rα, IL-2Rβ, and IL-2Rγ. The IL-2Ra is a type I transmembrane protein consisting of a 219 amino acid extracellular domain, a 19 amino acid transmembrane domain and a 13 amino acid intracellular domain, which is not involved in the transduction of IL-2 signals. Proteolytic processing of IL-2Ra releases the entire extracellular domain of IL-2Ra thereby generating a 219 amino acid soluble protein called soluble IL-2Ra (sIL-2Ra). The homodimeric form binds IL-2 (KD=10 mM) and facilitates IL-2 signaling. The secreted sIL-2Ra is expressed on leukemia cells, lymphoma cells, newly activated T and B cells, as well as on approximately 10% of NK cells. Recombinant human sIL-2R alpha is a 24.8 kDa protein containing 219 amino acid residues consisting of only the extracellular domain of IL-2R alpha. Due to glycosylation, IL-2R alpha has an approximate molecular weight of 31 kDa based on SDS-PAGE gel and Mass Spectrometry.

Stato fisico

Lyophilized from 1x PBS.

Ricostituzione

Centrifuge the vial prior to opening. Reconstitute in 1x PBS pH 7.2 to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
