簡單介紹：

重組大鼠粘膜相關上皮趨化因子/ CCL28蛋白與其它公司提供的重組蛋白不同，rRtMEC/CCL28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.重組大鼠粘膜相關上皮趨化因子/ CCL28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：

重組大鼠粘膜相關上皮趨化因子/ CCL28蛋白

Synonyms CCK1

Species Rat

Source Escherichia coli.

Molecular Weight 重組大鼠粘膜相關上皮趨化因子/ CCL28蛋白Approximately 13.1 kDa, a single non-glycosylated polypeptide chain containing 116 amino acids.

Quantity 5μg/20μg/1000μg

AA Sequence SEAILPIASS CCTEVSHHIP RRLLERVNSC SIQRADGDCD LAAVILHVKR RRICVSPHNP TLKRWMSASE MKNGKENLCP RKKQDSGKDR KGHTPRKHGK HGTRRIHGTH DHEAPR

Purity > 96 % by SDS-PAGE and HPLC analyses.

Biological Activity 重組大鼠粘膜相關上皮趨化因子/ CCL28蛋白Fully biologically active when compared to standard. The biologically active determined by a chemotaxis bioassay using human lymphocytes is in a concentration range of 5.0-50 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, 200 mM NaCl.

Endotoxin 重組大鼠粘膜相關上皮趨化因子/ CCL28蛋白Less than 1 EU/μg of rRtMEC/CCL28 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 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 CCL28 belongs to CC family chemokine, also named mucosae-associated epithelial chemokine (MEC). The CCL28 mRNA is highly expressed by epithelial cells of diverse tissues including normal and pathological colon, salivary gland, mammary gland, trachea and rectum. The protein signals through CCR3 and CCR10, and chemotactic for resting CD4, CD8 T-cells and eosinophils. CCL28 shares the most homology with CCL27/CTACK.
