IL-2R gamma/CD132 Protein, Mouse (HEK293, His)

IL-2R gamma (CD132), a type I cytokine receptor expressed on leucocyte subsets, is a receptor for IL-2. IL-2R gamma forms heterodimer with IL-2R beta, and increases the affinity of IL-2R beta for IL-2. IL-2R gamma takes part in inflammatory response and mediates activation of the cells ^[1][2]. IL-2R gamma plays an important role in the development, activation, proliferation, differentiation and regulation of lymphocytes and other cell types^[3]. IL-2R gamma/CD132 Protein, Mouse (HEK293, His) is a recombinant mice extracellular region of IL-2R gamma with a C-Terminal 6*His tag, which is produced in HEK293 cells.

IL-2R gamma (CD132), a receptor for IL-2, is a member of the type I cytokine receptor family and type 5 subfamily. IL-2R gamma is expressed in spleen and thymus^[1].
The sequence of amino acids in IL-2R beta differs in different species. Mice IL-2R gamma shares 80.70% aa sequence identity with rats. Mice IL-2R gamma shares <75% aa sequence identity with human.
IL-2R gamma has low-affinity for IL-2, but has intermediate affinity for IL-2 when forming heterodimer with IL-2R beta. IL-2R beta/gama heterodimer complex transduces a signal when IL-2 concentrations are relatively high^[2]. IL-2R gamma can be utilized by the IL-2, IL-4, IL-7, IL-9, and IL-15 receptor, and takes part in the development, activation, proliferation, differentiation and regulation of lymphocytes and other cell types^[3]. IL-2R gamma maintains mainstream B- and T-cell generation and function, and is also important for NK-cell development^[4]. Mutations of L-2R gamma causes severe impairment in innate and adaptive immunity in mice^[5].
IL-2R gamma is involved in inflammatory response, and mediates activation of the cells^[1].

IL-2R gamma binds to IL-2 in recombinant IL-2R gamma plasmid (pGEX-4T-1-IL-2Rγ)-transfected 293T cells^[6].

≥ 95%, as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of 20 mM Tris-HCl, 150 mM NaCl, pH 8.5.
Note: For SPR assay, please replace the buffer. Primary amine components (e.g., Tris, imidazole) can affect protein-coupled chips.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O. For long term storage it is recommended to add a carrier protein (0.1% BSA, 5% HSA, 10% FBS or 5% Trehalose).

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US;may vary elsewhere.
