Accession: <a href="http://www.uniprot.org/uniprot/Q29056" target="_blank">Q29056</a>

Gene IDs: <a href="http://www.ncbi.nlm.nih.gov/gene/397499" target="_blank">397499</a>

种属: Porcine

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

来源: Escherichia coli.

内毒素水平: Less than 0.1 EU/μg of rPoIL-1RA as determined by LAL method.

活性: Fully biologically active when compared to standard. The ED₅₀ as determined by inhibiting IL-1α-dependent proliferation of murine D10S cells is less than 50 ng/ml, corresponding to a specific activity of > 2.0 × 10⁴ IU/mg in the presence of 75 pg/ml rPoIL-1α.

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 1 × PBS, pH 7.4, 1 mM DTT.

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.
