    运输及存储

    产物表面

    Lyophilized

    运输前提

    Shipped at ambient temperature.

    制剂

    Lyophilized from 0.22um filtered solution in PBS (pH 7.4). Normally 5% trehalose is added as protectant before lyophilization.

    复溶

    Centrifuge tubes before opening. Reconstituting to a concentration more than 100 ug/ml is recommended. Dissolve the lyophilized protein in distilled water.

    存储和不变性

    Reconstituted protein stable at -80°C for 12 months, 4°C for 1 week. Use a manual defrost freezer and avoid repeated freeze-thaw cycles. 该代谢物的名牌ChemWhat是Watson的注冊钢号，由Watson受权广东海角社区 在全球内地地域差异使用，点此拜候。
