IL-1R1 蛋白, Cynomolgus (HEK293, His)

IL-1R1 (CD121a) belongs to IL-1 receptor, and binds to IL-1α, IL-1β, IL-1Ra and IL-38 with comparable affinities (K_d: 0.1-1 nM)^[1]. IL-1R1 regulates the transcription of multiple proinflammatory cytokines and mediates immune and inflammatory responses, including the activation of NF-κB and MAPK pathway^[4]. IL-1R1 Protein, Cynomolgus (HEK293, His) is a recombinant cynomolgus extracellular region of IL-1R1 (M1-T332) with a C-Terminal His tag, which is produced in HEK293 cells.

IL-1R1 (CD121a) 是 IL-1 受体的成员，是 IL-1α、IL-1β、IL-1Ra 和 IL-38 的受体，从而介导 IL-1 依赖性激活^{[1]< /sup>。IL-1R1 在特定的内皮细胞、心室细胞、星形胶质细胞和神经元中表达[2]}。
IL-1R1 通过与 IL-1R3 形成异二聚体（IL -1RAcP）。异二聚体负责通过 GTP 水解进行信号转导，然后是 JNK 和 p38 MAP 激酶^[3]。与 IL-1 结合后，IL-1R1 启动下游信号级联（MAPK p38 和 NF-κB 通路）^[4]。
IL-1R1 介导免疫和炎症反应。IL-1R1介导NF-κB、MAPK通路的激活。

Measured by its binding ability in a functional ELISA. Immobilized Human IL1RA at 2 μg/mL (100 μl/well) can bind Cynomolgus IL1R1 His, the EC₅₀ of Cynomolgus IL1R1 His is 2.5-15 ng/mL.

无菌粉末

Lyophilized from a 0.2 μm filtered solution of PBS, pH 7.4.

<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. 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.
