簡單介紹：

重組人嗜酸性粒細胞趨化因子-3 / CCL26蛋白與其它公司提供的重組蛋白不同，rHuEotaxin-3/CCL26蛋白產品為采用CFS的無細胞麥胚蛋白合成系統表達出來的重組蛋白，可表達出對細胞有毒性、易被蛋白酶降解的蛋白；并獲得具有良好的可溶性，并有翻譯后修飾、從而部分具有功能的蛋白.同時獨有的全自動蛋白純化技術則簡便高效，將蛋白純化過程中對蛋白的損傷降低到*小程度.重組人嗜酸性粒細胞趨化因子-3 / CCL26蛋白（全長序列）產品可用于Western Blot驗證、抗體制備、蛋白檢測、ELISA等試驗中.

詳情介紹：

重組人嗜酸性粒細胞趨化因子-3 / CCL26蛋白

Synonyms CC chemokine IMAC, MIP-4-alpha, TSC-1

Species Human

Accession Q9Y258

GeneID 10344

Source 重組人嗜酸性粒細胞趨化因子-3 / CCL26蛋白Escherichia coli.

Molecular Weight Approximately 8.4 kDa, a single non-glycosylated polypeptide chain containing 71 amino acid residues.

Quantity 5μg/20μg/1000μg

AA Sequence TRGSDISKTC CFQYSHKPLP WTWVRSYEFT SNSCSQRAVI FTTKRGKKVC THPRKKWVQK YISLLKTPKQ L

Purity > 97 % by SDS-PAGE and HPLC analyses.

Biological Activity 重組人嗜酸性粒細胞趨化因子-3 / CCL26蛋白Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human CCR3 transfected HEK293 cells is in a concentration range of 0.5-2.0 μg/ml.

Physical Appearance Sterile Filtered White lyophilized (freeze-dried) powder.

Formulation Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4.

Endotoxin Less than 1 EU/μg of rHuEotaxin-3/CCL26 as determined by LAL method.

Reconstitution 重組人嗜酸性粒細胞趨化因子-3 / CCL26蛋白We recommend that this vial be briefly centrifuged prior to opening to bring the contents to the bottom. Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 °C. Further dilutions should be made in appropriate buffered solutions.

Storage This lyophilized preparation is stable at 2-8 °C, but should be kept at -20 °C for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 °C. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 °C to -70 °C. Avoid repeated freeze/thaw cycles.

Background CCL26 is novel CC family chemokine, also known as TARC (thymus and activation regulated chemokine). It is encoded by CCL26 gene, which is located on Chr.7 in humans, and ubiquitously expressed at low levels in various tissues including heart and ovary. CCL26 elicits its effects activity by binding to the cell surface chemokine receptor CCR3, and chemotactic for eosinophils and basophils.
