Accession: <a href="http://www.uniprot.org/uniprot/Q9HBE4" target="_blank">Q9HBE4</a> Gene IDs: <a href="http://www.ncbi.nlm.nih.gov/gene/59067" target="_blank">59067</a> 种属: Human 纯度: > 97 % by SDS-PAGE and HPLC analyses. 来源: Escherichia coli. 内毒素水平: Less than 1 EU/μg of Recombinant HumanIL-21 as determined by LAL method. 活性: Fully biologically active when compared to standard. The ED<sub>50</sub> as determined by a cell proliferation assay using human N1186 T cells is less than 20 ng/ml, corresponding to a specific activity of > 5.0 × 10<sup>4</sup> IU/mg. 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. 形态: Lyophilized from a 0.2 μm filtered concentrated solution in PBS, pH 7.4. 储存/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. 产品信息订购:
