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金瓊脂糖粉,超長DNA凝膠電泳
產(chǎn)品英文名 SeaKem® Gold Agarose
產(chǎn)品中文名 SeaKem®金瓊脂糖粉
適用:長片段及超長片段DNA跑膠
SeaKem® Gold Agarose是一種高凝膠強(qiáng)度,低EEO(電滲),標(biāo)準(zhǔn)凝膠溫度的瓊脂糖。這種遺傳學(xué)技術(shù)級別(Genetic Technology Grade™ Agarose)的瓊脂糖zui適于在脈沖場凝膠電泳法(pulsed field gel electrophoresis-PFGE)實(shí)驗(yàn)中快速分辨巨大堿基對DNA:長片段及超長片段DNA。由于SeaKem®Gold Agarose金膠瓊脂糖的低EEO特性,在SeaKem®Gold瓊脂糖凝膠電泳實(shí)驗(yàn)中,DNA電泳遷移率遠(yuǎn)遠(yuǎn)超過傳統(tǒng)的瓊脂糖凝膠電泳。PFGE的跑膠時(shí)間依使用的緩沖液和瓊脂糖濃度的不同可減少至原電泳時(shí)間的50%。因其高凝膠強(qiáng)度,即使是使用低濃度(0.5%的SeaKem Gold瓊脂糖凝膠),操作處理依然很方便,從而允許在常規(guī)電泳中分離更大的DNA fragment并減少PFGE中的DNA分離的耗時(shí)。為了更好的在PFGE電泳后對大片段DNA fragment回收,推薦使用 SeaPlaque™ GTG™ Agarose和ß-Agarase。
