產(chǎn)品詳情
簡單介紹：
重組鼠胸腺和激活調(diào)節(jié)趨化因子/ CCL17蛋白與其它公司提供的重組蛋白不同，rMuTARC/CCL17蛋白產(chǎn)品為采用CFS的無細胞麥胚蛋白合成系統(tǒng)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(shù)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.重組鼠胸腺和激活調(diào)節(jié)趨化因子/ CCL17蛋白（全長序列）產(chǎn)品可用于Western Blot驗證、抗體制備、蛋白檢測、ELISA等試驗中.

| Purity | > 97 % by SDS-PAGE and HPLC analyses. |
| Biological Activity | Fully biologically active when compared to standard. The biologically active determined by a chemotaxis bioassay using human T-lymphocytes is in a concentration range of 1.0-10 ng/ml. |
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | 重組鼠胸腺和激活調(diào)節(jié)趨化因子/ CCL17蛋白Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4. |
| Endotoxin | Less than 1 EU/μg of rMuTARC/CCL17 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 | 重組鼠胸腺和激活調(diào)節(jié)趨化因子/ CCL17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 | Murine CCL17 also known as TARC, Small-inducible cytokine A17, Thymus and activation-regulated chemokine and SCYA17, is encoded by the CCL17 gene located on the chromosome 8. Among CC chemokine family members, CCL17 has approximately 24 – 29 % amino acid sequence identity with RANTES, MIP-1α, MIP-1β, MCP-1, MCP-2, MCP-3 and I-309. CCL17 is a secreted protein and expressed by thymus cells constitutively and phytohemagglutinin-stimulated peripheral blood mononuclear cells transiently. It signals through the chemokine receptors CCR4 and CCR8 and displays chemotactic activity for T lymphocytes and some other leukocytes. CCL17 play an important role in skin diseases such as atopic dermatitis, bullous pemphigoid and mycosis fungoides. Recombinant CCL17 has been shown to be chemotactic for T cell lines but not monocytes or neutrophils. |
