Introduction
趋化因子配体 21 是属于 CC 趋化因子家族的小细胞因子。 这种趋化因子也称为 6Ckine、exodus-2 和次级淋巴组织趋化因子。 CCL21 主要在淋巴结中表达,与其他 CC 趋化因子相比,它对淋巴细胞具有趋化性。 CCL21 的基因位于人类第 9 号染色体上。CCL21 通过与称为 CCR7 的细胞表面趋化因子受体结合来引发其作用。
Description
Exodus-2 Mouse Recombinant produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 110 amino acids and having a molecular mass of 12kDa.
The CCL21 is purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered White lyophilized powder.
Formulation
Lyophilized from a concentrated solution in water containing 20mM Phosphate buffer and 0.15M NaCl pH-7.4.
Solubility
It is recommended to reconstitute the lyophilized Exodus2 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions
Stability
Lyophilized Exodus-2 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CCL21 should be stored at 4°C between 2-7 days and for future use below -18°C. For long term storage it is recommended to add a carrier protein . Please prevent freeze-thaw cycles.
Purity
Greater than 97.0% as determined by -PAGE & RP-HPLC.
