產(chǎn)品詳情
簡(jiǎn)單介紹：
重組人類單核細(xì)胞趨化蛋白-2 / CCL8蛋白與其它公司提供的重組蛋白不同，rHuMCP-2/CCL8蛋白產(chǎn)品為采用CFS的無(wú)細(xì)胞麥胚蛋白合成系統(tǒng)表達(dá)出來(lái)的重組蛋白，可表達(dá)出對(duì)細(xì)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(shí)獨(dú)有的全自動(dòng)蛋白純化技術(shù)則簡(jiǎn)便高效，將蛋白純化過(guò)程中對(duì)蛋白的損傷降低到*小程度.重組人類單核細(xì)胞趨化蛋白-2 / CCL8蛋白（全長(zhǎng)序列）產(chǎn)品可用于Western Blot驗(yàn)證、抗體制備、蛋白檢測(cè)、ELISA等試驗(yàn)中.

| Accession | P80075 |
| GeneID | 6355 |
| Source | Escherichia coli. |
| Molecular Weight | 重組人類單核細(xì)胞趨化蛋白-2 / CCL8蛋白Approximately 8.9 kDa, a single non-glycosylated polypeptide chain containing 76 amino acids. |
| Quantity | 2μg/10μg/1000μg |
| AA Sequence | QPDSVSIPIT CCFNVINRKI PIQRLESYTR ITNIQCPKEA VIFKTKRGKE VCADPKERWV RDSMKHLDQI FQNLKP |
| Purity | > 96 % by SDS-PAGE and HPLC analyses. |
| Biological Activity | Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using human peripheral blood monocytes is in a concentration range of 10-100 ng/ml. |
| Physical Appearance | 重組人類單核細(xì)胞趨化蛋白-2 / CCL8蛋白Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB, pH 7.4, 100 mM NaCl. |
| Endotoxin | Less than 1 EU/μg of rHuMCP-2/CCL8 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 | 重組人類單核細(xì)胞趨化蛋白-2 / CCL8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 | Human CCL8, also known as monocyte chemotactic protein 2 (MCP-2), is belonging to the CC chemokine family. It is encoded by the gene CCL8. MCP-2 has two homogeneous MCP-1 (CCL2) and MCP-3 (CCL7). These three MCPs were found by IL-1-beta triggered human MG-63 osteosarcoma cells. CCL8 shares 62 % amino acid sequence identity with MCP-1, and shares 58 % amino acid sequence identity with MCP-2. CCL8 has chemotactic function for monocytes, eosinophils and neutrophils. In addition, it can also chemoattract activated NK cells. |
