Recombinant Mouse Il2ra Protein, His-tagged, Alexa Fluor 647 conjugated

• Cat.No.: Il2ra-4021MAF647
• Product Overview: Alexa Fluor 647 conjugated recombinant Mouse Il2ra (Glu22-Lys236) protein was fused to His-tag at C-terminus and expressed in human 293 cells (HEK293).

Specification

• Species: Mouse
• Source: HEK293
• Tag: His
• Protein Length: Glu22-Lys236
• Description: Interleukin-2 receptor subunit alpha (IL2RA) is also known as IL-2R subunit alpha, IL-2-RA, IL2-RA, TAC antigen, p55, CD antigen CD25, is a type I transmembrane glycoprotein. IL2RA is expressed on activated T cells and regulatory T cells, and is capable of binding IL2 with low affinity by itself. However, a ligand-induced high affinity heterotrimeric receptor complex is produced when IL2RA is associated non-covelently with the IL2 receptor beta and gamma chain, and subsequently initiates the intacellular signal pathways such as MAPK or JAK/STAT. On dendritic cells (DC), CD25 has been previously regarded as an activation marker, while both murine and human DC can express CD25, they do not express the beta-chain of the IL-2 receptor, which is indispensable for the execution of IL-2 signaling.
