B7-1 Protein, Cynomolgus, Recombinant (hFc)

产品编号 TMPJ-00630

Cynomologous Cluster of Differentiation 80, also called B7-1, is a member of cell surface immunoglobulin superfamily.It is expressed on the surface of antigen-presenting cells including activated B cells, macrophages and dendritic cells.CD80 plays key, yet distinct roles in the activation of T cells. B7-1/CD80 and B7-2/CD86, together with their receptors CD28 and CTLA4, constitute one of the dominant co-stimulatory pathways that regulate T- and B- cell responses. CD80 is mostly expressed on the surface of antigen-presenting cells including activated B cells, macrophages and dendritic cells. Although both CTLA-4 and CD28 can bind to the same ligands, CTLA-4 binds to B7-1 and B7-2 with a 20-100 fold higher affinity than CD28 and is involved in the down-regulation of the immune response. CD80 is thus regarded as promising therapeutic targets for autoimmune diseases and various carcinomas.

实验操作小课堂

常见问题解答

问PEG300 可以用 PEG400 替代吗？

答PEG300 具有适度的粘稠度，有利于药物的溶解和给药过程，同时也能够提供良好的耐受性，不会对动物造成不良影响。PEG400 可以替代 PEG300。 PEG600 不是很建议，因为熔点接近常温。

问产品溶解需要超声吗？如果没有超声仪怎么办？

答超声可以加快粉末的溶解速度，如果您的化合物溶解不了，建议您尝试超声。如果您没有超声仪，建议您选择较低母液浓度，或者较少粉末量，尝试溶解。

问抑制剂能否用于动物实验？

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

问动物实验常用溶解方法？

答首先，您需要确认给药剂量、给药方式。对于具体的产品，优先找引用我们产品的文献里的使用方法，再找其他文献里的配方。如果没有相关的文献，且该化合物的 DMSO 溶解度比较好，我们推荐通用配方: 10% DMSO+40% PEG300+5% Tween-80+45% Saline/PBS/ddH2O。溶剂依次加入，尽量溶解后再加入下一个溶剂。正常鼠建议 DMSO 浓度在 10% 以下，裸鼠体弱鼠等配方的 DMSO 浓度建议在 2% 以下，根据溶液是否澄清，助溶剂 PEG300、Tween-80 的比例可以适当调整。如果有其他助溶剂也可以使用。以上配方仅供参考，体内配方并不是绝对的，需要根据不同情况进行调整。建议先取少量化合物测试配方，再进行大量配制。配完也可以再使用超声、加热等方式助溶，看看能不能澄清一点。腹腔注射对粉末的溶解度要求比较高，建议购买盐形式化合物。如果给药剂量比较大，也有报道使用混悬液进行腹腔给药的。对于灌胃给药，且剂量比较大的情况下，建议用 0.5% CMC-Na 配置成均匀混悬液进行给药。

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。
