中文别名: SDF-1α蛋白; CXCL12α蛋白

Gene IDs: <a href="http://www.ncbi.nlm.nih.gov/gene/6387" target="_blank">6387</a>

种属: Human

来源: Escherichia coli.

纯度: > 97 % by SDS-PAGE and HPLC analyses.

内毒素水平: Less than 1 EU/μg of Recombinant HumanSDF-1α/CXCL12α as determined by LAL method.

活性: Fully biologically active when compared to standard. The biological activity determined by a chemotaxis bioassay using PHA and Recombinant HumanIL-2 activated human peripheral blood T-lymphocytes is in a concentration range of 20-80 ng/ml.

形态: Lyophilized from a 0.2 μm filtered concentrated solution in 20 mM PB pH 7.0, 130 mM NaCl.

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.

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.
