微波法制备琼脂糖
1. 准备烧杯,容积是溶液体积的2-4倍。
2. 加入常温 1X 或 0.5X电泳缓冲液。放搅拌棒。
3. 一边快速搅拌溶液,一边慢慢撒入琼脂糖粉。
4. 拿掉搅拌棒,if not Teflon® coated.
5. 加热前称量烧杯溶液总重。
6. 塑料盖好烧杯。
7. 塑料盖上穿小孔用来透气。
8. 微波高功率加热烧杯直到气泡出现。
9. 拿出烧杯。
注意:任何微波加热过的溶液都会过热,导致搅动时会起泡。
10. 小心轻晃烧杯以重悬未溶解粉末和凝胶碎片。
11. 高功率重新加热烧杯,直到沸腾。
12. 在沸点维持1分钟,或是等到颗粒全部溶解。
13. 拿出烧杯。
14. 小心轻晃烧杯以*混匀琼脂糖溶液。
15. 溶解后,补充足量热的蒸馏水,恢复起始称重。
16. *混匀。
17. 冷却到 50°C。

Microwave lnstructions for Agarose Preparation
1. Choose a beaker that is 2-4 times the volume of the solution.
2. Add room temperature 1X or 0.5X electrophoresis buffer and a stir bar to the beaker.
3. Slowly sprinkle in the agarose powder while the solution is rapidly stirred.
4. Remove the stir bar if not Teflon® coated.
5. Weigh the beaker and solution before heating.
6. Cover the beaker with plastic wrap.
7. Pierce a small hole in the plastic wrap for ventilation.
8. Heat the beaker in the microwave oven on High
power until bubbles appear.
9. Remove the beaker from the microwave oven.
Caution: Any microwaved solution may become superheated and foam over when agitated.
10. GENTLY swirl the beaker to resuspend any settled powder and gel pieces.
11. Reheat the beaker on HIGH power until the solution comes to a boil.
12. Hold at boiling point for 1 minute or until all of the particles are dissolved.
13. Remove the beaker from the microwave oven.
14. GENTLY swirl the beaker to thoroughly mix the agarose solution.
15. After dissolution, add sufficient hot distilled water to obtain the initial weight.
16. Mix thoroughly.
17. Cool the solution to 50°C-50°C prior to casting.
Hot Plate Instructions for Agarose Preparation

3. Slowly sprinkle the agarose powder while the solution is rapidly stirred.
4. Weigh the beaker and solution before heating.
5. Cover the beaker with plastic wrap.
6. Pierce a small hole in the plastic wrap for ventilation.
7. Bring the solution to a boil while stirring.
8. Maintain gentle boiling until all the agarose is dissolved (approximay 10 minutes).
9. Add sufficient hot distilled water to obtain the initial weight.
10. Mix thoroughly.
11. Cool the solution to 50°C-60°C prior to casting.
LONZA SeaKem® Gold Agarose金琼脂糖粉,超长DNA凝胶电泳
产品英文名 SeaKem® Gold Agarose
产品中文名 SeaKem®金琼脂糖粉
适用:长片段及超长片段DNA跑胶
SeaKem® Gold Agarose是一种高凝胶强度,低EEO(电渗),标准凝胶温度的琼脂糖。这种遗传学技术级别(Genetic Technology Grade™ Agarose)的琼脂糖zui适于在脉冲场凝胶电泳法(pulsed field gel electrophoresis-PFGE)实验中快速分辨巨大碱基对DNA:长片段及超长片段DNA。由于SeaKem®Gold Agarose金胶琼脂糖的低EEO特性,在SeaKem®Gold琼脂糖凝胶电泳实验中,DNA电泳迁移率远远超过传统的琼脂糖凝胶电泳。PFGE的跑胶时间依使用的缓冲液和琼脂糖浓度的不同可减少至原电泳时间的50%。因其高凝胶强度,即使是使用低浓度(0.5%的SeaKem Gold琼脂糖凝胶),操作处理依然很方便,从而允许在常规电泳中分离更大的DNA fragment并减少PFGE中的DNA分离的耗时。为了更好的在PFGE电泳后对大片段DNA fragment回收,推荐使用 SeaPlaque™ GTG™ Agarose和ß-Agarase。
