NKG2-D type II integral membrane protein (NKG2D) is a type II transmembrane glycoprotein which belongs to the CD94/NKG2 family. NKG2D is expressed on natural killer (NK) cells, CD8+ alpha-beta and gamma-delta T-cells. As an activating and costimulatory receptor, it involved in immunosurveillance upon binding to various cellular stress-inducible ligands displayed at the surface of autologous tumor cells and virus-infected cells. It provides both stimulatory and costimulatory innate immune responses on activated killer (NK) cells, leading to cytotoxic activity. It stimulates perforin-mediated elimination of ligand-expressing tumor cells. Signaling involves calcium influx, culminating in the expression of TNF-alpha. NKG2D participates in NK cell-mediated bone marrow graft rejection and survival of NK cells. It Binds to ligands belonging to various subfamilies of MHC class I-related glycoproteins including MICA, MICB, RAET1E, RAET1G, ULBP1, ULBP2, ULBP3 (ULBP2>ULBP1>ULBP3) and ULBP4.
Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.
复溶
Always centrifuge tubes before opening.Do not mix by vortex or pipetting.
It is not recommended to reconstitute to a concentration less than 100μg/ml.
Dissolve the lyophilized protein in distilled water.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.如要长期保存，建议使用含载体蛋白(如 0.1%BSA、10%FBS、5%HSA)的溶液进一步稀释，如果是做无血清培养或者动物体内实验时，细胞因子中不能含有BSA、FBS 和 HAS，可以使用海藻糖作为载体，然后分装冻存于-20℃至-80℃。注:分装保存时建议使用低吸附的管子，并避免反复冻融；稀释分装浓度不低于 10μg/mL，分装体积不低于10μL。
分装后的蛋白在≤-20°C 下可稳定保存 3 个月。
