常见问题解答

问重组蛋白产品该如何保存？

答1) 存储条件:重组蛋白产品收到后，如不立即使用，应当保存在 -20℃ 至 -80℃ 的条件下。冻干粉可稳定保存 12 个月以上，液体类产品在 -80℃ 条件下可保存 6-12 个月。已复溶的重组蛋白样品需尽快用完，如果不能在一周内用完，需在 -20℃ 至 -80℃ 保存，可保存 3 个月以上\n2) 避免反复融冻:重组蛋白产品应注意避免反复冻融，建议将重组蛋白产品分装成多份。分装冻存时，建议选择含有一定浓度载体蛋白的溶液或培养基复溶产品。产品浓度不低于 100 ug/mL，且每管的体积不小于 20 uL。

问如何将冻干的重组蛋白配置为储备液？

答在打开盖⼦之前，先使用 10000-12000 rpm 的转速进行离心，20-30 秒，将附着在管盖或管壁上的冻⼲粉收集到管底，以避免损失。大多数蛋白可通过加入无菌蒸馏水来重新溶解。如果需要除水以外的其他稀释剂，产品 COA 中会对其进行说明。一般储备液浓度建议不要低于 100 μg/mL，分装储存避免反复冻融。

问重组蛋白产品是如何运输的？

答大部分重组蛋白产品为冻⼲粉，对温度不敏感，在室温下稳定，一般室温或蓝冰运输。对于液体类蛋白，一般采用⼲冰运输。如果您收到产品时发现冰盒已经融化，无需担心，蛋白可以正常使用，短时间内不会影响产品质量。如果特定蛋白在室温下不稳定，我们会提供相应的低温运输方式，以确保产品质量不受影响。

问为什么重组蛋白的体积和质量与预期不符？

答蛋白冻干粉由蛋白原液冻干而来，冻干粉质量不等同于蛋白质量。由于冻⼲产品的体积大⼩受多种因素影响，包括冻⼲前缓冲液的组分、盐离⼦浓度以及产品本身的浓度等。冻⼲粉可能看上去很多，也可能肉眼不易观察到，这些都是正常现象，请您放心使用。在收到产品后，照常复溶、使用或分装储存即可。

问重组蛋白有吗？

答您需要什么种属的蛋白呢，对表达系统和标签有要求吗，用于什么实验？

复溶方法	A Certificate of Analysis (CoA) containing reconstitution instructions is included with the products. Please refer to the CoA for detailed information.
存储	It is recommended to store recombinant proteins at -20°C to -80°C for future use. Lyophilized powders can be stably stored for over 12 months, while liquid products can be stored for 6-12 months at -80°C. For reconstituted protein solutions, the solution can be stored at -20°C to -80°C for at least 3 months. Please avoid multiple freeze-thaw cycles and store products in aliquots.
运输方式	In general, Lyophilized powders are shipping with blue ice.
研究背景	CD47 contains 1 Ig-like V-type (immunoglobulin-like) domain and is a receptor for the C-terminal cell binding domain of thrombospondin. It may play a role in membrane transport and signal transduction. CD47 is also a membrane protein, which is involved in the increase in intracellular calcium concentration that occurs upon cell adhesion to extracellular matrix. It is very broadly distributed on normal adult tissues, as well as ovarian tumors, being especially abundant in some epithelia and the brain. CD47 may play a role in membrane transport and/or integrin dependent signal transduction. It may prevent premature elimination of red blood cells. It also may be involved in membrane permeability changes induced following virus infection. By acting as an adhesion receptor for THBS1 on platelets, CD47 plays a role in both cell adhesion and in the modulation of integrins. It also plays an important role in memory formation and synaptic plasticity in the hippocampus.Cancer ImmunotherapyCo-inhibitory Immune Checkpoint TargetsImmune CheckpointImmune Checkpoint Detection: AntibodiesImmune Checkpoint Detection: ELISA AntibodiesImmune Checkpoint Detection: WB AntibodiesImmune Checkpoint TargetsImmunotherapyTargeted Therapy
