| 概述 | |
|---|---|
| 種屬 | Canine |
| 形態(tài) | Lyophilized from a 0.2 µm filtered concentrated solution in 25 mM Sodium Succinate, pH 5.0, 60 mM NaCl, with 0.1 % Tween-80. |
| 來源 | Escherichia coli. |

| 內(nèi)毒素水平 | Less than 0.1 EU/µg of rCaIFN-γ as determined by LAL method. |
| 活性 | Fully biologically active when compared to standard. The ED50 as determined by an anti-viral assay using A-72 canine fibroma cells infected with vesicular stomatitis virus (VSV) is less than 2.0 ng/ml, corresponding to a specific activity of > 5.0 × 105 IU/mg. |
| Accession # | P42161 |
| 預(yù)期分子量 | Approximay 16.9 kDa, a single non-glycosylated polypeptide chain containing 143 amino acids. |

| 溶解方法 | 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. |
| 保存方法 | 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. |
| 純度 | > 97 % by SDS-PAGE and HPLC analyses. |
| Gene IDs | 403801 |
