    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. 该物品的该品牌ChemWhat是Watson的登记品牌，由Watson受权吉林海角社区 在华人台湾地区地方凭借，点此拜候。
