Description
Product Highlights
- Fast – single-tube protocol that eliminates wash steps, giving high-yield, PCR-ready DNA in just 15 minutes
- Simple – few protocol steps greatly reduce the risk of sample loss and contamination and minimizes manual effort
- Sensitive – incorporates MyTaq HS DNA Polymerase that exhibits increased affinity for DNA, thereby improving yield of even the most challenging targets
- Specific - MyTaq HS DNA Polymerase is an antibody-mediated hot-start enzyme that remains completely inactive during PCR set-up to prevent non-specific amplification
- Flexible – ideal for amplifying any target up to 5 kb from DNA extracted from mammalian tissue samples
- Convenient – mastermix facilitates PCR set-up and includes a red dye for improved pipetting ease / accuracy and to enable direct gel loading
Product Description
Many DNA extraction methods can be laborious and time consuming or involve the use of hazardous chemicals. MyTaq™ Extract-PCR Kit offers a rapid, easy and safer alternative for the extraction and amplification of DNA from a variety of tissue types. MyTaq Extract-PCR Kit is particularly suited to solid tissues such as mouse tail or mouse ear. The DNA extractions are performed in a single-tube, without the need for multiple washing steps, greatly reducing the risk of sample loss and contamination.
The extracted DNA is amplified in a proprietary buffer system using MyTaq HS Red Mix, the latest generation of very high-performance polymerase unique to Meridian. To further reduce non-specific amplification, MyTaq HS uses antibody hot-start technology. The advanced formulation of MyTaq HS Red Mix allows fast cycling conditions to be used, greatly reducing the reaction time without compromising PCR specificity or yield.
The rapid MyTaq Extract-PCR Kit maximizes sensitivity while minimizing contamination risks to deliver improved success rates in applications such as mouse DNA characterization. The single tube lysis protocol and MyTaq HS Red Mix maximize sensitivity, while minimizing contamination risks and significantly reduce reaction times as well as delivering improved success rates in protocols such as mouse DNA characterization
Applications
- High-throughput genotyping from mammalian tissue
- Detection of transgenes
- Knockout analysis

RMgX + RX = R-R + MgX2.
这个反应需要的能量比生成格氏试剂的高,
因此降低反应温度是第一个选择。
其次, 增加镁得摩尔比, 让 RX与镁有更多机会反应, 而不是与RMgX。
第三, 降低RX的浓度, 即用更多的溶剂, 因为溶剂和格氏试剂有很显著的溶剂络合。
第四, 缓慢滴加RX., 即降低RX.在反应体系的浓度。
第五, 增加搅拌速率, 即, 让RX.与镁有更好的接触。

Cell-Based ELISA
的优点:
Cell-Based ELISA
(基于细胞的
ELISA
)是一种全新的
ELISA
技术,有两个最突出的优点:
1.1
不需要抽提蛋白、包被微孔板:细胞直接在微孔板里培养,待检测的时候,将细胞固定在微孔板上并
进行通透处理即可。这样就避免了抽提蛋白时,由于客观和主观上引起样品的损失而导致实验结果在一定
程度上偏离了实际情况。
同时不用包被微孔板,
简化了实验流程,
有助于提高效率。
科研人员在一个
96
孔
酶联板上,便能检测目标细胞蛋白经刺激或抑制作用后的表现。由于省去抽提蛋白和裂解细胞的步骤,样
本的损失也能降到最低,比起其他普通的
ELISA
测定方法,这项全新的
ELISA
技术能更快速、更方便
地一次检测大量的细胞内蛋白。
1.2
可同时检测两种不同蛋白:
封闭后加入两种抗不同蛋白且来源于不同宿主的一抗,
然后再加入不同的
二抗,加入两种荧光底物,检测两个波长。同时检测两种蛋白的好处是显而易见的,可以减少工作量,此
外还可以满足一些特殊的实验需要,例如,需要测定某个蛋白的磷酸化比例,就需要测定磷酸化蛋白的数
量和总蛋白的数量,这两个测定在同一次实验进行,有助于消除实验误差,得到更为精确的实验结果。

、
Cell-Based ELISA
的两种技术:
某些公司发展了双通道
Cell-Based ELISA
技术;
双通道与单通道
Cell-based ELISA
比较:
双通道
cell-based ELISA
,顾名思义,即一次可以同时检测两种目的蛋白,
R&D Systems
提供的
Cell-based ELISA
就是双通道
cell-based ELISA
,原理略:(需要荧光检测方式和相应仪器);
单通道
cell-based ELISA
,即一次只能检测一种目的蛋白,他和普通
ELISA
的主要区别在于样品处理过
程
3
、
cell-based ELISA
的应用:
该产品,最多发展起来的是用于检测磷酸化和非磷酸化蛋白的相对含量;
4
、有
cell-based ELISA
产品的公司:目前,多家
elisa
产品提供
商均
提供
cell
based
elisa
试剂盒,
如
Rnd
systems
,
raybiotech
,
ebioscience
,
millipore
等公司;
5
、如何自己进行
cell based elisa
实验?
事实上,根据单通道的
cell based elisa
原理,可以自己建立
cell based elisa
实验系统;
细胞加入培养板中;
加入刺激物或者抑制剂进行培养;
对细胞进行固定或者封闭;
加入第一抗体;
加入
HRP
结合的二抗(二抗的选择,同
western blot
);
加入底物进行显色;
天然产物,大多都有颜色,
存在干扰,多数情况下需要做样品的阴性对照,
尽量能用荧光的方法,
之前我们做过,将两个试剂盒的方法合并后,做的,
效果还可以
1. 姜黄素是一个典型的HAT抑制剂。
2. 针对P300: 在大约10年前,Cole和他的同事设计出了一种p300/CBP抑制剂,发表在nature杂志上。
希望能帮到你,望采纳!
