National Diagnostics公司的美国ND蛋白沉淀试剂盒，具有以下优点：

1.从复杂的样品中回收所有的蛋白

2.能够从低至0.25µg/ml浓度的BSA蛋白样品中回收100ng的微量蛋白

3.比TCA更加温和

4.比乙腈和硫酸铵沉淀更加有效可靠

ND蛋白沉淀试剂盒沉淀过程温和且易于操作。它可以保证在低的蛋白浓度下大量的回收溶液中的蛋白，其他方法中易丢失的蛋白也可以用该试剂盒沉淀回收。常规以及复杂的非常规的实验都适用，真正做到了温和性、简便性和有效性。

 
The ND Protein Precipitation Kit is mild on samples and easy to use. It casts the finest net of any procedure, allowing the high yield collection of all proteins in solution, precipitating even the most dilute proteins. The ND Protein Precipitation Kit allows collection of proteins that would be missed by other methods.

Ideal for both routine and difficult work, the ND Protein Precipitation Kit stands alone among all methods. It offers the best combination of mildness, simplicity and effectiveness in protein precipitation.
 

High Yield Recovery

10ug BSA in 1ml vol and 50 ng of BSA in 200ul were prepared from stock and precipitated following kit instructions. 10ug and 50ng of BSA in 5 ul were prepared as controls. After running on a 12% gel, lanes 2 and 3 show control and recovered 10ug BSA. Lanes 5 and 6 show control and recovered 50ng BSA. Densitometry of 10ug BSA showed 91.9% recovery.

Simplicity of Method

Reagent A and Reagent B form a coprecipitate with the protein.
 

After a simple wash, the protein pellet is ready to be redissolved in desired buffer.
