本试剂是用Tris-HCl(pH8.0)饱和过的DNA提取酚试剂,为浅黄色透明液体,有刺激性气味,上层为Tris盐酸缓冲液,pH>7.8,下层为酚相,内加有抗氧化的8-羟基喹啉。本品适用于分离DNA。
该试剂仅用于科研领域,不适用于临床诊断或其他用途。
自备材料
操作步骤(仅供参考)
取适量组织裂解液,按以下步骤进行DNA提取:
1. 调节pH:确保裂解液pH值在8.0左右(可加入0.1倍体积的1 mol/L Tris-HCl,pH 8.0进行调节)。
2. 有机抽提:依次加入以下试剂:
0.5倍体积的DNA提取酚试剂(注:使用时静置,取下层有机相;上层为Tris-HCl溶液,用于防止下层有机相氧化)
0.5倍体积的氯仿:异戊醇(24∶1)
振荡10秒充分混匀,随后冰浴15分钟。
3. 离心分离:离心后,小心吸取上层水相至新离心管中。
4. 沉淀DNA:加入等体积异丙醇,混匀后沉淀DNA。
5. 洗涤与溶解:沉淀经75%乙醇漂洗1次,微干燥后溶于适量TE缓冲液中,备用。
注意事项
1. DNA提取酚试剂有较强的腐蚀性,应尽量避免皮肤接触或吸入体内。如发现变为红色或棕色,表明已发生氧化,不能继续使用。
2. 为了您的安全和健康,请穿实验服并戴一次性手套操作。
3. 试剂开封后请尽快使用,以防影响后续实验效果。
This reagent is a DNA extraction phenol reagent saturated with Tris-HCl (pH 8.0). It appears as a light yellow, clear liquid with a pungent odor. The upper layer consists of Tris-HCl buffer with pH > 7.8, while the lower layer is the phenolic phase, which contains 8-hydroxyquinoline as an antioxidant. This product is suitable for DNA isolation.
This reagent is for research use only and is not intended for clinical diagnosis or other purposes.
Materials to Prepare
Tissue Lysis Buffer
Tris-HCl (1M, pH 8.0)
Chloroform
Isoamyl alcohol
Isopropanol
75% Ethanol
TE Buffer
Procedure (For Reference Only)
Take an appropriate amount of Tissue Lysis Buffer and follow the steps below for DNA extraction:
1. Adjust pH: Ensure the pH of the lysis buffer is around 8.0 (add 0.1 volume of 1 mol/L Tris-HCl, pH 8.0 for adjustment if necessary).
2. Organic Extraction: Sequentially add the following reagents:
Vortex for 10 seconds to mix thoroughly, then incubate on ice for 15 minutes.
3. Centrifugation and Separation: After centrifugation, carefully transfer the upper aqueous phase to a new centrifuge tube.
4. DNA Precipitation: Add an equal volume of isopropanol, mix well, and precipitate the DNA.
5. Washing and Dissolution: Wash the precipitate once with 75% ethanol, air-dry briefly, and dissolve in an appropriate volume of TE buffer for subsequent use.
Precautions
1. DNA Phenol Reagent is highly corrosive. Avoid skin contact or inhalation. If the reagent turns red or brown, it indicates oxidation and should not be used.
2. For your safety and health, please wear a lab coat and disposable gloves during operation.
3. Use the reagent as soon as possible after opening to prevent affecting subsequent experimental results.
