產(chǎn)品詳情
簡單介紹：
重組人Neuregulin 1αEGF域蛋白與其它公司提供的重組蛋白不同，rHuNRG1-α蛋白產(chǎn)品為采用CFS的無細(xì)胞麥胚蛋白合成系統(tǒng)表達(dá)出來的重組蛋白，可表達(dá)出對細(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.重組人Neuregulin 1αEGF域蛋白（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.
詳情介紹：
重組人Neuregulin 1αEGF域蛋白
| Species | Human |
| Accession | Q02297 |
| GeneID | 3084 |
| Source | Escherichia coli. |
| Molecular Weight | 重組人Neuregulin 1αEGF域蛋白Approximately 7.4 kDa, a single non-glycosylated polypeptide chain containing 65 amino acids. |
| Quantity | 10μg/50μg/1000μg |
| AA Sequence | SHLVKCAEKE KTFCVNGGEC FMVKDLSNPS RYLCKCQPGF TGARCTENVP MKVQNQEKAE ELYQK |
| Purity | > 97 % by SDS-PAGE and HPLC analyses. |
| Biological Activity | 重組人Neuregulin 1αEGF域蛋白Fully biologically active when compared to standard. The ED50 as determined by a cell proliferation assay using serum free human MCF-7 cells is less than 40 ng/ml, corresponding to a specific activity of ＞ 2.5 × 104 IU/mg. |
| Physical Appearance | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation | Lyophilized from a 0.2 μm filtered solution in 20 mM PB, pH 6.0, 150 mM NaCl. |
| Endotoxin | Less than 0.1 EU/μg of rHuNRG1-α as determined by LAL method. |
| Reconstitution | 重組人Neuregulin 1αEGF域蛋白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. |
