Total OXPHOS Blue Native WB Antibody Cocktail

Product details

Blue Native polyacrylamide gel electrophoresis (BN-PAGE) is a simple and effective way to subfractionate mitochondrial proteins as intact complexes on a single gel (in one dimension). It can be used to detect altered assembly of these complexes arising from mutations in subunits, mutations in assembly factors, or mtDNA depletion. This type of analysis has been performed with biopsy samples, platelets and fibroblast cells from patients with suspected mitochondrial diseases.

In this method, multisubunit enzymes bind a charged dye Coomassie brilliant blue which allows their electrophoretic separation in the first dimension by the size of the complex. Complexes I-V with masses ranging from 950K to 200K are well resolved in the first dimension. The separated proteins can then be transferred to nitrocellulose membrane/PVDF by electrophoresis and Complexes I, II, III, IV and ATP synthase can be detected by mAbs against CI-NDUFA9 ab14713(MS111), CII-70 kDa subunit ab14715(MS204), CIII-Core protein 2 ab14745(MS304), CIV-subunit IV ab14744(MS407) and CV-alpha subunit ab14748(MS507) respectively. Such one dimensional gels, are best analyzed by using single mAbs against each complex. Other Complex I mAbs are available for BNPAGE, specifically anti-GRIM-19 ab110240(MS103) and anti-20 kDa ab110242(MS105). A sample of purified bovine heart mitochondria ab110338(MS802) is available as a BNPAGE control sample.

Sometimes a greater separation of enzymes is necessary - it is possible to separate the proteins within each individual complex. To do this, blotting is NOT performed after the first (NATIVE) dimension, instead gels are turned 90 degrees and run in a perpendicular second dimension which is denaturing (NON-NATIVE). In this way the protein subunits within each complex are separated. Abcam provides an optimized pre-mixed cocktail of the mAbs to SIMULTANEOUSLY detect Complexes I-V after 2nd dimension blotting (specifically the cocktail contains ab14713 (MS111), ab14715 (MS204), ab14745 (MS304), ab14744(MS407) and ab14748 (MS507).
