M2201 Klenow I Promega試劑? 產(chǎn)品描述：
其它組分：
DNA Polymerase 10X Buffer【子貨號(hào)：M195A，包裝：1 x 1ml，，運(yùn)保溫度：-20℃】
DNA Polymerase I Large (Klenow) Fragment【子貨號(hào)：M220A，包裝：1 x 150u，，運(yùn)保溫度：-20℃】
描述：
說明 |
| DNA Polymerase I Large (Klenow) Fragment (DNA 聚合酶I 大(Klenow) 片段) 是DNA 依賴的DNA 聚合酶，它沒有完整的E. coli DNA Polymerase I 所具有的 5` → 3` 外切酶活性，但保留了5` → 3` 聚合酶、3` → 5` 外切酶及鏈置換活性。該酶是DNA 聚合酶I 的C- 末端片段，68kDa。Klenow 片段5` → 3` 聚合酶活性經(jīng)常被用于以非標(biāo)記的或標(biāo)記的dNTPs 補(bǔ)平5`- 突出端、單鏈或雙鏈DNA 模板測(cè)序、合成寡核苷酸進(jìn)行體外突變、cDNA第二鏈合成以及制備單鏈DNA探針。3` → 5` 外切酶活性可用于從3`- 突出端產(chǎn)生平末端。

特點(diǎn) |
| • 靈活性：DNA Polymerase I Large (Klenow) Fragment 可用于多種分子實(shí)驗(yàn)。在多種Promega 1× 內(nèi)切酶緩沖液中它都能保持活性。 |
原廠資料：
DNA Polymerase I Large (Klenow) Fragment is a DNA-dependent DNA polymerase that lacks the 5´→3´ exonuclease activity of intact E. coli DNA Polymerase I but retains its 5´→3´ polymerase, 3´→5´ exonuclease and strand displacement activities. The enzyme is a 68kDa C-terminal fragment of DNA Polymerase I. The 5´→3´ polymerase activity of Klenow Fragment can be used to fill in 5´-protruding ends with unlabeled or labeled dNTPs, to sequence single- or double-stranded DNA templates, for in vitro mutagenesis using synthetic oligonucleotides, for cDNA second-strand synthesis and to generate single-stranded DNA probes. The 3´→5´ exonuclease activity can be used to generate blunt ends from a 3´-overhang.
Features - Benefits
Flexible: DNA Polymerase I Large (Klenow) Fragment may be used in a variety of molecular applications. It is also active in many Promega 1X restriction enzyme buffers.
May Be Heat-Inactivated: DNA Polymerase I Large (Klenow) Fragment is inactivated by heating at 75°C for 10 minutes.
Provided with 10X Reaction Buffer: 500mM Tris-HCl (pH 7.2 at 25°C), 100mM MgSO4, 1mM DTT.
