DETAILS

MP Biomedicals - 02190320

A nondenaturing zwitterionic detergent for solubilizing proteins. It has a more polar head group than CHAPS, giving it greater solubility. CHAPSO has a high Cmc (8mM) and does not denature membrane-bound proteins. It can solubilize the opiate receptor in a state exhibiting reversible binding of opiates.

Sigma Aldrich - C9551

Application
具有类似于 CHAPS 特性的非变性两性离子洗涤剂，然而由于具有更强极性的头部基团而更易溶解。适用于内在膜蛋白的增溶。

Sigma Aldrich - C3649

Application
具有类似于 CHAPS 特性的非变性两性离子洗涤剂，然而由于具有更强极性的头部基团而更易溶解。适用于内在膜蛋白的增溶。

Sigma Aldrich - C4695

Application
具有类似于 CHAPS 特性的非变性两性离子洗涤剂，然而由于具有更强极性的头部基团而更易溶解。适用于内在膜蛋白的增溶。

Sigma Aldrich - 374237

Application
A nondenaturing zwitterionic detergent with characteristics similar to CHAPS, although it is more soluble due to a more polar head group. Useful for the solubilization of integral membrane proteins.

Sigma Aldrich - 26675

Application
A nondenaturing zwitterionic detergent with characteristics similar to CHAPS, although it is more soluble due to a more polar head group. Useful for the solubilization of integral membrane proteins.
Other Notes
Zwitterionic detergent that does not denature membrane-bound proteins. ATPase from the plasma membrane of Beta vulgaris1
