Melanotransferrin/CD228 蛋白, Human (HEK293, His)

Melanotransferrin, or CD228, is vital for cellular iron uptake, binding a single iron atom per subunit. The protein is involved in internalization and recycling to the cell membrane, with additional potential versatility in zinc binding. Melanotransferrin/CD228 Protein, Human (HEK293, His) is the recombinant human-derived Melanotransferrin/CD228 protein, expressed by HEK293 , with C-His labeled tag. The total length of Melanotransferrin/CD228 Protein, Human (HEK293, His) is 690 a.a., with molecular weight of 78-88 kDa.

黑转铁蛋白，也称为 CD228，通过每个亚基结合一个铁原子，在细胞铁吸收中发挥着至关重要的作用。该蛋白质参与内化和随后再循环回细胞膜。值得注意的是，黑转铁蛋白表现出结合锌的能力，表明金属离子相互作用的潜在多功能性。

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

无菌粉末.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4. Normally 8% trehalose is added as protectant before lyophilization.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

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.
