N2511 Recombinant RNasin Promega試劑? 產(chǎn)品描述：
其它組分：
Recombinant RNasin® Ribonuclease Inhibitor【子貨號：N251A，包裝：1 x 2,500u，，運保溫度：–20°C】
描述：
說明 |
| 天然的和重組的RNasin® 核酸酶抑制劑具有廣譜的抑制RNase 活性的性質(zhì)，包括抑制中性型(neutral type) 真核RNase。該抑制劑的分子量為50kDa，按1:1 的比例與RNase 非共價結(jié)合發(fā)揮抑制作用。RNasin® Ribonuclease Inhibitor 與RNase( 如RNase A) 結(jié)合的Ki 值大約是10-14M。Promega 提供兩種不同的抑制劑：天然的RNasin® Ribonuclease Inhibitor 和重組的RNasin® Ribonuclease Inhibitor。兩種產(chǎn)品均通過離子交換和親和層析相結(jié)合的純化方法純化得到。
|
特點 |
| • 抑制常見的真核RNase：RNasin® Ribonuclease Inhibitor 具有廣譜RNase 抑制特性，包括 RNase A、 RNase B、 RNase C 和人類胎盤RNase，不抑制RNase T1、 S1 核酸酶、曲霉(Aspergillus ) 中的 RNase 以及RNase H、RNase ONE® Ribonuclease。 |
原廠資料：
RNases are ubiquitous, cause RNA degradation and can compromise RNA integrity. Recombinant RNasin® Inhibitor is a 50kDa protein that inhibits RNase A family and human placental RNases by noncovalently binding to RNases in a 1:1 ratio. Recombinant RNasin® Inhibitor does not inhibit RNase T1, S1 nuclease, RNase from Aspergillus, RNase H, RNase ONE™ Ribonuclease and enzymes for downstream applications such as GoScript™ Reverse Transcriptase, AMV/M-MLV reverse transcriptases, SP6, T7/T3 RNA polymerase, and Taq DNA polymerases.

Features - Benefits
Broad-Spectrum RNase Inhibition: Inhibits common eukaryotic RNases.
Compatible: Does not inhibit SP6, T7 or T3 RNA Polymerase; GoScript™ Reverse Transcriptase, AMV or M-MLV Reverse Transcriptase; or Taq DNA polymerase.
Flexible: Functional across wide pH range (pH 5–8) enabling use in many downstream assays.
Recombinant: Made in bacteria, minimizing the chances of human nucleic acid contamination.
Applications
RT-PCR and RT-qPCR.
Useful in any applications where eukaryotic RNase contamination is a potential problem.
Protection of mRNA in cDNA synthesis reactions.
In vitro transcription/translation.
Increase yield and activity of polysomes.
Improvement of in vitro virus replication.
Improvement of RNA translation in homologous systems.
Performing RNase-free antibody staining.
Enhancement of RNA yields from Riboprobe® System RNA synthesis reactions.

Unit Definition
One unit is defined as the amount of RNasin® Ribonuclease Inhibitor required to inhibit the activity of 5ng of ribonuclease A by 50%. Activity is measured by the inhibition of hydrolysis of cytidine 2,3´-cyclic monophosphate by ribonuclease A.
