Interleukin-2 receptor subunit beta/Il2rb CSB-EP011650MO1 is a recombinant partial-length protein containing the extracellular domain (24-240aa) of mouse Il2rb. This protein was fused with a 6xHis-tag at the N-terminus and expressed in E.coli. Its identity was validated by LC-MS/MS analysis. Its purity is greater than 90% determined by SDS-PAGE. A molecular weight band of about 30kDa was visualized on gel under reducing conditions. The recombinant Il2rb protein may find applications in specific antibody production and signal transduction associated with IL2rb.
IL2rb, also called CD122, is the IL-2R β-chain, which is shared with IL-15R. Upon T-cell activation, IL-2Rα (CD25) is rapidly induced and help IL2rb and IL-2Rγc (CD132) come closer, constituting an intermediate affinity receptor that is sufficient to elicit the IL2 signaling pathways. signaling through IL2rb is indispensable for the differentiation and function of cells and NK cells. Xiaomei Yuan etc. demonstrated that IL2rb blockade preferentially affected major populations of islet-associated pathogenic cells by reducing their abundance and suppressing their differentiation into diabetogenic cells. The blockade of IL2rb restores immune tolerance, inhibits insulitis, and diabetes in nonobese diabetic (NOD) mice.

|Target Protein Sequence
Note: The complete sequence including tag
sequence, target protein sequence and linker sequence could be provided upon request.
Liquid or Lyophilized powder
Note: We will preferentially ship the format that
we have in stock, however, if you have any special requirement for the format, please remark your
requirement when placing the order, we will prepare according to your demand.
|| If the delivery form is liquid, the default storage buffer is Tris/PBS-based buffer, 5%-50% glycerol.
Note: If you have any special requirement for the
glycerol content, please remark when you place the order.
If the delivery form is lyophilized powder, the buffer before lyophilization is Tris/PBS-based buffer,
6% Trehalose, pH 8.0.
||We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Please reconstitute protein in deionized sterile water to a concentration of 0.1-1.0 mg/mL.We recommend to add 5-50% of glycerol (final concentration) and aliquot for long-term storage at -20°C/-80°C. Our default final concentration of glycerol is 50%. Customers could use it as reference.
||Store at -20°C/-80°C upon receipt, aliquoting is necessary for mutiple use. Avoid repeated freeze-thaw
||The shelf life is related to many factors, storage state, buffer ingredients, storage temperature
and the stability of the protein itself.
Generally, the shelf life of liquid form is 6 months at -20°C/-80°C. The shelf life of lyophilized
form is 12 months at -20°C/-80°C.
||3-7 business days
||Repeated freezing and thawing is not recommended. Store working aliquots at 4°C for up to one week.
