Highlights: CHAPS Buffer 
  • Strong cell lysis and protein extraction capacity while preserving protein conformation and protein-protein interaction for co-immunoprecipitation (Co-IP) analysis.
  • Effective as a stand alone reagent for cell lysis and protein extraction.
  • Contains a non-amine buffer (HEPES) enabling cross-linking with NHS-ester derivatives.
  • Compatible with Bradford, Lowry and BCA protein assays.
  • 60 ml volume:  Suitable for two hundred 10-cm culture plates, or six hundred wells in 6-well dishes.  120 ml volume is also available.


Properties of CHAPS Lysis and Immunoprecipitation Buffer
CHAPS is a zwitterionic detergent with strong membrane dissolution capacity while maintaining protein conformation and protein-protein interaction.  The CHAPS reagent provides an effective stand alone buffer for cell lysis and protein extraction as well as a reagent suitable for downstream immunoprecipitation-pull down approaches.

The addition of calcium chloride to the CHAPS reagent preserves calcium dependent protein-protein interaction, whereas the addition of EDTA abrogates the interaction.  The CHAPS immunoprecipitation reagent is offered with or without 1 mM calcium chloride and/or 1mM EDTA to investigate the roles of calcium in protein-protein interactions.

(*Note:  The CHAPS Buffer with formulations containing calcium chloride, or EDTA, have been employed to characterize calcium dependent chaperone protein interactions, such as with calnexin or calreticulin (see references 2-6 below).

Representative Data with CHAPS Immunoprecipitation and Cell Lysis Reagent (pH 8.0)

Figure 1 
Co-immunoprecipitation (Co-IP) of a trafficking protein receptor (COPII) with a cation channel (TRPC-6).  HEK293 cells were co-transfected with plasmid DNA encoding TPRC-6 and a HA epitope tagged component of COPII (sec24).  Cell lysis and immunoprecipitation were performed in CHAPS Buffer as summarized in the product manual.  Western blotting (WB) was performed with the antibodies indicated in the figure.

                              IP:  Anti-HA COPII                      IP:  Anti-HA COPII
                                WB: Anti-TRPC6                        WB:  COPII

Figure 2 
Co-immunoprecipitation (Co-IP) of a calcium binding protein with a multisubunit target protein 1 employing the FIVEphoton CHAPS immunoprecipitation reagent.  A larger amount of target protein 1 associates with the calcium binding protein when expressed alone, as compared to co-expression (and presumed assembly) with protein 2.  Protein 1 reveals higher molecular weight forms due to post-translational modifications.
