簡單介紹：

重組人Exodus-2 / CCL21蛋白與其它公司提供的重組蛋白不同，rHuExodus-2/CCL21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Exodus-2 / CCL21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Exodus-2 / CCL21蛋白

Synonyms 6Ckine, Beta-chemokine Exodus-2, SLC

Species Human

Accession O00585

GeneID 6366

Source 重組人Exodus-2 / CCL21蛋白Escherichia coli.

Molecular Weight Approximately 12.2 kDa, a single, non-glycosylated polypeptide chain containing 111 amino acids.

Quantity 5μg/20μg/1000μg

AA Sequence SDGGAQDCCL KYSQRKIPAK VVRSYRKQEP SLGCSIPAIL FLPRKRSQAE LCADPKELWV QQLMQHLDKT PSPQKPAQGC RKDRGASKTG KKGKGSKGCK RTERSQTPKG P

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

Biological Activity 重組人Exodus-2 / CCL21蛋白Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human lymphocytes is in a concentration range of 10-100 ng/ml.

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

Formulation Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 150 mM NaCl.

Endotoxin Less than 1 EU/μg of rHuExodus-2/CCL21 as determined by LAL method.

Reconstitution 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 重組人Exodus-2 / CCL21蛋白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 CCL21 is encoded by CCL21 gene that is located in Chr. 9 and shows 21-33 % identity to other CC chemokines. This chemokine contains the four conserved cysteines characteristic of β chemokines plus two additional cysteines in its unusually long carboxylterminal domain. CCL21 is highly expressed in lymph nodes of certain endothelial cells, and in the spleen and appendix. It elicits effects by binding with CCR7, having functions of T and B lymphocytes chemotaxis and inhibiting hematopoiesis.
