Methylamp DNA Modification Kit

背景資料 Methylamp DNA修飾試劑盒是一套完整實驗組件,它使用Epigentek所*的簡化流線型亞硫酸氫鹽法,來執行DNA甲基化分析。整個實驗需要1小時55分鐘,其結果遠勝于其競爭對手。本試劑盒能適應于MS-PCR,實時定量MS-PCR,甲基化測序和焦磷酸測序,等同于甲基化的微陣列。
產品描述 Methylamp DNA修飾試劑盒包含DNA樣本亞硫酸氫鹽轉換修飾所需要的全部試劑。DNA與亞硫酸氫鹽試劑反應,能特異性的使DNA化學變性,產生單鏈DNA,從而使胞嘧啶脫氨基形成尿嘧啶。修飾液中含有的*的DNA保護劑,能在亞硫酸氫鹽處理后阻止化學性或者嗜熱性降解DNA。無毒性的修飾DNA捕獲液能使DNA緊密的綁定在圓柱過濾器,因此DNA的清洗能有效地去除殘余的亞硫酸氫鈉或者鹽。然后修飾的DNA洗提,儲存在-20度可以保持2個月。
產品特點 1、目前市場zui快的操作流程,*的反應條件完成實驗僅需要1小時55分鐘;2、*轉換未甲基化的胞嘧啶為尿嘧啶,被修飾的DNA> 99·98%;3、修飾過程中具備zui低的DNA降解,能阻止超過90%的DNA損失;4、啟動DNA修飾zui低要求:僅需要50pg或者20個細胞;5、非常簡單,可信賴的實驗結果和穩定的修飾條件。
保存建議 在接收到Epigentek試劑盒后請按照說明書建議,使用不同的保存條件或溫度來保存試劑盒內組分。

Product Overview



The Methylamp™ DNA Modification Kit is a complete set of essential components which enables the experimenter to perform DNA methylation analysis using Epigentek's uniquely simplified and streamlined bisulfite method. The entire procedure can be completed within a mere 1 hour and 55 minutes and produces far superior results than any competitor kits. The Methylamp™ DNA Modification Kit is suitable for MS-PCR, real time MS-PCR, methylation sequencing, and pyrosequencing, as well as methylation microarray.

WHY CHOOSE THE METHYLAMP™ DNA MODIFICATION KIT?
 

  • The fastest procedure available on the market, which can be completed within 1 hour and 55 minutes with consistent reaction conditions.
  • Compley converts unmethylated cytosine into uracil: modified DNA > 99.98%.
  • The lowest degradation of DNA in the modification process: more than 90% of DNA loss can be prevented.
  • The lowest requirement of starting DNA for modification: only 50 pg or 20 cells.
  • Extremely simple, reliable, and consistent modification conditions.
Principle & Procedure


The Methylamp™ DNA Modification Kit contains all reagents required for bisulfite conversion on a DNA sample. DNA is chemically denatured to allow bisulfite reagent to react specifically with single-stranded DNA, thereby deaminating cytosine and creating a uracil residue. The unique DNA protection reagents contained in the modification buffer can prevent the chemical and thermophilic degradation of DNA in the bisulfite treatment. The non-toxic modified DNA capture buffer enables DNA to bind tightly to the column filter, thus clean DNA can be carried out on the column to effectively remove residual sodium bisulfite and salts. Modified DNA can then be eluted and stably stored at –20°C for up to 2 months.

High throughput version also available. [Cat. # P-1008]
Fast DNA Modification version using heating process also available. [Cat. # P-1010]


 

SCHEMATIC PROCEDURE: COMPARATIVE OVERVIEW:




The different amounts of DNA isolated from a serum sample were chemically modified using the Methylamp™ DNA Modification Kit. Real time PCR was performed by using a pair of primers and a probe designed to amplify both methylated and unmethylated alleles of β-actin.

Frequently Asked Q's

1. What is difference between one-step DNA modification and two-step DNA modification?
In the one-step DNA modification, DNA is denatured by heating, which allows DNA denaturation and bisulfite modification to be carried out simultaneously. One-step DNA modification is suitable for the labs which are equipped with thermal cycler and requires simple and fast procedures for DNA modification. In the two-step DNA modification, DNA is denatured chemically followed by bisulfite treatment. It is suitable for general DNA modification using DNA isloated from various sources. Because one-step DNA modification may increase DNA degradation, a higher starting DNA amount may be required for one-step DNA modification than for two-step DNA modifcation.

2. How much starting DNA is required for DNA modification with this kit?
The starting DNA required for DNA modification can be as low as 50 pg. The signal of the modified DNA can be detected with real-time PCR.

3. Why are only 90 minutes required for the actual DNA modification?
With our unique modification composition, 90 minutes is sufficient for more than 99% C-T conversion while DNA degradation is greatly prevented. We have observed that increase in modification time did not significantly increase C-T conversion, while yield of modified DNA was significantly reduced most likely due to increased DNA degradation.

4. Can the modified DNA with this kit be stored for a long time?
The modified DNA generated with this kit can be stored for 2 months at -20°C. The modified DNA could be stored for as long as 6 months at -80°C.

5. Can the kit be used for modifying DNA from formalin-fixed and paraffin-embedded (FFPE) samples?
DNA extracted from FFPE samples is often fragmented. The kit can be used for FFPE samples as the modification solution included in the kit contains DNA stabilizing reagents that avoid a further fragmentation of DNA caused in modification process.
