Nonident P-40 (NP-40) is a non-ionic detergent commonly used in cell lysis and protein extraction buffers. This buffer solubilizes membrane proteins without denaturing them, enabling their extraction and purification. The non-ionic nature of NP-40 detergent allows for the extraction of cytoplasmic proteins from both adherent and suspension-cultured mammalian cells without disrupting the native structure and function of the proteins. NP-40 has a high boiling point (~290°C) and a low melting point (< 0°C). The density is around 1.06 g/cm³ at 20°C. Due to its mild, non-denaturing properties, it is suitable for downstream applications like immunoassays (e.g., ELISA, Luminex), Western blotting, and immunoprecipitation. This NP-40 buffer contains glycerol which helps stabilize proteins by preventing denaturation and maintaining their native conformation. Glycerol improves the solubility of proteins, particularly hydrophobic proteins, by creating a more favorable environment for them to remain in solution. The addition of glycerol to lysis buffers can lead to improved protein yields during extraction processes.
Advantages:
-
The non-denaturing nature of NP-40 helps to maintain protein-protein interactions, enabling the study of protein complexes.
-
It can selectively lyse the cytoplasmic membrane while leaving the nuclear membrane intact.
Applications:
-
It is used for solubilizing and extracting membrane proteins and protein complexes without denaturing them.
-
It enables the study of membrane-associated proteins in their native state.
- It is commonly used in cell lysis, immunoprecipitation, and protein purification protocols.
