本试剂是用柠檬酸饱和过的RNA提取酚试剂,为无色透明的液体,有刺激性气味,上层为柠檬酸溶液层,pH<5.5,下层为有机溶剂。本品不含8-羟基喹啉,通常与异硫氰酸胍一起使用,用于RNA的提取。
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,依次加入以下试剂进行RNA提取:
1. 加入0.1倍体积的2 mol/L醋酸钠(pH 4.0),维持溶液酸性环境。
2. 加入1倍体积的RNA提取酚试剂(注:使用时静置,取下层有机相;上层为柠檬酸溶液,用于防止下层有机相氧化)。
3. 加入0.2倍体积的氯仿:异戊醇(49∶1),振荡10秒充分混匀,随后冰浴15分钟。
离心后,小心吸取上层水相,加入等体积异丙醇沉淀RNA。沉淀经75%乙醇漂洗1次,微干燥后溶于10 μL DEPC处理水中,备用。
1. RNA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 an RNA extraction phenol reagent saturated with citric acid. It appears as a colorless, clear liquid with a pungent odor. The upper layer consists of a citric acid solution with pH < 5.5, while the lower layer is the organic solvent. This product does not contain 8-hydroxyquinoline and is typically used in conjunction with guanidine isothiocyanate for RNA extraction.
This reagent is for research use only and is not intended for clinical diagnosis or other purposes.
Materials to Prepare
Tissue Lysis Buffer
Sodium Acetate Buffer (2M, pH 4.0)
Chloroform
Isoamyl alcohol
Isopropanol
75% Ethanol
TE Buffer
Procedure (For Reference Only)
Take an appropriate amount of Tissue Lysis Buffer and sequentially add the following reagents for RNA extraction:
Add 0.1 volume of 2 mol/L Sodium Acetate (pH 4.0) to maintain an acidic environment.
Add 1 volume of RNA Phenol Reagent (Note: Allow the reagent to stand before use; use the lower organic phase. The upper layer is the citric acid solution, which prevents oxidation of the lower organic phase).
Add 0.2 volume of Chloroform:Isoamyl alcohol (49:1) , vortex for 10 seconds to mix thoroughly, then incubate on ice for 15 minutes.
After centrifugation, carefully transfer the upper aqueous phase to a new tube. Add an equal volume of isopropanol to precipitate the RNA. Wash the precipitate once with 75% ethanol, air-dry briefly, and dissolve in 10 μL of DEPC-treated water for subsequent use.
Precautions
RNA 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.
For your safety and health, please wear a lab coat and disposable gloves during operation.
Use the reagent as soon as possible after opening to prevent affecting subsequent experimental results.
