- SynonymCCL19,MIP-3 beta,MIP-3-beta,ELC,MIP3B,SCYA19,EBI1 ligand chemokine
- SourceActiveMax® Human CCL19 / MIP-3 beta, Tag Free (CC9-H5215) is expressed from human 293 cells (HEK293). It contains AA Gly 22 - Ser 98 (Accession # Q99731-1).Predicted N-terminus: Gly 22Request for sequence
- Molecular Characterization

This protein carries no "tag".
The protein has a calculated MW of 8.8 kDa. The protein migrates as 12 kDa under reducing (R) condition (SDS-PAGE) due to glycosylation.
- EndotoxinLess than 1.0 EU per μg by the LAL method.
- Purity
>90% as determined by SDS-PAGE.
- Formulation
Lyophilized from 0.22 μm filtered solution in PBS, pH7.4. Normally trehalose is added as protectant before lyophilization.
Contact us for customized product form or formulation.
- Reconstitution
Please see Certificate of Analysis for specific instructions.
For best performance, we strongly recommend you to follow the reconstitution protocol provided in the CoA.
- Storage
For long term storage, the product should be stored at lyophilized state at -20°C or lower.
Please avoid repeated freeze-thaw cycles.
This product is stable after storage at:
- -20°C to -70°C for 12 months in lyophilized state;
- -70°C for 3 months under sterile conditions after reconstitution.

ActiveMax® Human CCL19 / MIP-3 beta, Tag Free on SDS-PAGE under reducing (R) condition. The gel was stained overnight with Coomassie Blue. The purity of the protein is greater than 90%.
- BackgroundC-C motif chemokine 19(CCL19) is as known as CK beta-11, ELC, MIP3B and SCYA19. May play a role not only in inflammatory and immunological responses but also in normal lymphocyte recirculation and homing. May play an important role in trafficking of T-cells in thymus, and T-cell and B-cell migration to secondary lymphoid organs. Binds to chemokine receptor CCR7. Recombinant CCL19 shows potent chemotactic activity for T-cells and B-cells but not for granulocytes and monocytes. Binds to atypical chemokine receptor ACKR4 and mediates the recruitment of beta-arrestin (ARRB1/2) to ACKR4.

用于酵母繁殖和筛选的培养基
SD是含有盐类、微量元素、维生素、氮源(不含氨基酸的酵母氮碱)和葡萄糖的合成基本培养基。
注意:氮源(不含氨基酸的酵母氮碱)是这种培养基用于筛选的关键,LB,YPD这种复合培养基因为用到了酵母提取物,蛋白胨,基本是氮源全营养的,肯定是不能用来做氮源筛选的
HT培养基添加剂(HT Supplement)为粉剂,经照射灭菌。每个包装可配制成10ml浓缩液(50X),用于杂交瘤细胞的筛选。
要培养293A细胞,请教各位大神,配制好的完全培养基4度能放置多久?
各位大神你们好:
我们是医疗器械工厂,只需配制环境监测和水检测的培养基,但是根据2015版药典规定,1105,141页有一句
而在9203,289页
“商品化的成品培养基除了应附有处方和使用说明外,还应注明有效期、贮藏条件、适用性检查试验的质控菌和用途”。
是否可以理解为只要供应商提供以上信息,使用厂家就可以不用做培养基适用性试验了?
如果购买的商品化的成品培养基不做培养基适用性试验,那么医疗器械的微生物检验将大大减少工作量了。
