常见问题解答

问超声一般需要多久？

答超声时长和溶解的量和浓度都有关，一般建议半个小时左右，如果浓度接近最大溶解度，或者需溶解的粉末较多，建议延长超声时间，并辅以加热。

问购买多次产品，发现颜色不同，怎么办？

答首先请您确认批次，如果是同一个批次产品，请联系技术同事核查产品颜色。如果是不同批次，请您放心，颜色不同可能是生产工艺不同而造成的，生产过程中的操作、温度、时间等因素可能会影响产品的颜色。如果您对该批次有疑虑，可在官网下载相应的质检报告，我们是对产品质量负责的。

问准备进行动物实验，收到大包装粉末后，如何分装溶解？

答根据配制出来的溶液是不是澄清的确定一次性能配多少：如果配制出来是澄清溶液，可以一次性多配制一些，储存于4度冰箱，大概一周配一次，放久了可能会失效；如果配制出来是混悬液，建议每次使用的时候都现配现用。

问抑制剂能否用于细胞实验？

答可以的，我们的抑制剂都可以用于细胞/体外实验。但有些化合物还没有用于细胞实验的文献，这种情况下，建议您先做预实验，确保研究的可行性。

问收到粉状试剂粘壁严重，如何处理？

答建议您用离心机 3000 rpm下离心一会儿,将粉末收集到管底。

缓冲液	Lyophilized from a solution filtered through a 0.22 μm filter, containing PBS, pH 7.4. Typically, a mixture containing 5% to 8% trehalose, mannitol, and 0.01% Tween 80 is incorporated as a protective agent before lyophilization.
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	Myeloid cell surface antigen CD33 also known as Sialic acid binding Ig-like lectin 3, CD33 antigen or Siglec-3, is a member of the immunoglobulin superfamily and SIGLEC (sialic acid binding Ig-like lectin) family. This Single-pass type I membrane protein contains 1 Ig-like C2-type (immunoglobulin-like) domain and 1 Ig-like V-type (immunoglobulin-like) domain. CD33 /Siglec-3 is a putative adhesion molecule of myelomonocytic-derived cells that mediates sialic-acid dependent binding to cells. CD33 /Siglec-3 preferentially binds to alpha-2,6-linked sialic acid. The sialic acid recognition site may be masked by cis interactions with sialic acids on the same cell surface. In the immune response, may act as an inhibitory receptor upon ligand induced tyrosine phosphorylation by recruiting cytoplasmic phosphatase(s) via their SH2 domain(s) that block signal transduction through dephosphorylation of signaling molecules. CD33/Siglec-3 induces apoptosis in acute myeloid leukemia (in vitro). CD33/Siglec-3 can function as a sialic acid-dependent cell adhesion molecule and that binding can be modulated by endogenous sialoglycoconjugates when CD33 is expressed in a plasma membrane.Cancer ImmunotherapyImmune CheckpointImmunotherapyTargeted Therapy
