概述 种属 Human 形态 Lyophilized from a 0.2 µm filtered solution in PBS, pH 7.4, containing 3 % Mannitol, 5 % Trehalose, 0.05 % Tween-80. 来源 Escherichia coli. 氨基酸序列 MCDLPETHSL DNRRTLMLLA QMSRISPSSC LMDRHDFGFP QEEFDGNQFQ KAPAISVLHE LIIFNLFT TKDSSAAWDE DLLDKFC YLNDLEAC VMQEERVGET PLMNADSILA VKKYFRRITL YLTEKKYSPC AWEVVRAEIM RSLSLSTNLQ ERLRRKE 内毒素水平 Less than 0.1 EU/µg of Recombinant HumanIFN-α1a as determined by LAL method. 活性 Fully biologically active when compared to standard. The specific activity determined by an anti-viral assay is no less than 1.0 × 108 IU/mg. Accession # P01562 预期分子量 Approximay 19.5 kDa, a single non-glycosylated polypeptide chain containing 167 amino acids. 性能 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. 纯度 > 97 % by SDS-PAGE and HPLC analyses. Gene IDs 3439
