复溶(Reconstitution) |
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℃. Further dilutions should be made in appropriate buffered solutions. |
储存条件
产品用冰袋装运,可在-20℃下保存1年。 复溶后在无菌条件下2至8°C保存1个月。 复溶后在-20°C无菌条件下保存3个月。 建议第一次使用时将蛋白质分成较小的量,并避免反复冻融循环。
注意事项
1.避免反复冻融循环。
