Abcam’s 1X Native lysis buffer is an efficient means of cell lysis and protein solubilization for both adherent and suspension cultured mammalian cells. This reagent extracts cytoplasmic, nuclear and membrane proteins. The detergent used in this buffer is relatively gentle and in many cases allows solubilization of protein complexes that retain enzymatic activity. On the flip side, the gentle nature of this lysis buffer means that it may result in extractions that are less complete than lysis buffers using more stringent detergents (e.g. ab156034). Native lysis buffer is compatible with many downstream applications, including enzyme activity assays, SDS-PAGE, Western blot, immunoprecipitation, ELISA and BCA assays.
