Animal-Free MCP-1/CCL2 蛋白, Pig (His)

MCP-1/CCL2 protein acts as a ligand for CCR2, inducing chemotactic responses and calcium mobilization. It attracts monocytes and basophils but not neutrophils or eosinophils. Animal-Free MCP-1/CCL2 Protein, Pig (His) is the recombinant pig-derived animal-Free MCP-1/CCL2 protein, expressed by E. coli , with N-His labeled tag.

CCL2 蛋白作为 CC 趋化因子受体 CCR2 的配体，通过结合和激活 CCR2 启动有效的趋化反应和细胞内钙动员。它对单核细胞和嗜碱性粒细胞表现出趋化活性，同时对中性粒细胞或嗜酸性粒细胞保持非活性。CCL2 在介导周围神经损伤引起的神经性疼痛中发挥着至关重要的作用，还可以增强含有多巴胺 D1 和 D2 受体的神经元中 NMDA 介导的突触传递，可能涉及 GRIN2B/NMDAR2B 的 MAPK/ERK 依赖性磷酸化。它以平衡状态下的单体或同型二聚体存在，通过蛋白聚糖的糖胺聚糖 (GAG) 侧链与内皮细胞相连，并通过其 Link 结构域与 TNFAIP6 相互作用。

Approximately 9.42 kDa

Greater than 95% as determined by reducing SDS-PAGE.

无菌粉末

Lyophilized from a 0.2 μm filtered solution of 1X PBS, pH 7.4.

<0.1 EU per 1 μg of the protein by the 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.
