CD45 蛋白, Mouse (HEK293, Fc)

The CD45 protein is a multifunctional member of the protein tyrosine phosphatase family with heparan sulfate proteoglycan and heparin binding activity as well as protein tyrosine phosphatase activity. It plays a crucial role in lymphocyte differentiation, macromolecular metabolic processes, and signal transduction regulation. CD45 Protein, Mouse (HEK293, Fc) is the recombinant mouse-derived CD45 protein, expressed by HEK293 , with C-hFc labeled tag.

CD45蛋白是蛋白酪氨酸磷酸酶家族的成员，具有多种功能，包括硫酸乙酰肝素蛋白聚糖结合活性、肝素结合活性和蛋白酪氨酸磷酸酶活性。它错综复杂地参与淋巴细胞分化、大分子代谢过程的正向调节、信号转导的调节等关键过程。CD45 在淋巴细胞相关途径的上游发挥作用，包括分化和激活，同时显着位于质膜、粘着斑和膜筏的外侧。CD45 广泛表达于第三鳃弓、消化系统、心血管系统、血淋巴系统和胎盘等多种结构中，其重要性因其与系统性红斑狼疮等疾病的相关性而得到强调。该基因的人类直系同源物 PTPRC（C 型蛋白酪氨酸磷酸酶受体）与丙型肝炎、多发性硬化症和严重联合免疫缺陷有关，凸显了其在免疫相关疾病中的关键作用。

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

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.
