纯度: > 96 % by SDS-PAGE and HPLC analyses.

来源: Escherichia coli.

内毒素水平: Less than 1 EU/μg of Recombinant HumanNRG1-β2 as determined by LAL method.

活性: 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 50 ng/ml, corresponding to a specific activity of > 2.0 × 10⁴ 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 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.
