  • Product overview

    250 µg, 500 µg or 750 µg monoclonal antibody irreversibly crosslinked to protein G-agarose beads which can immunocapture ~60 µg, ~120 µg or ~180 µg respectively of Complex I from heart mitochondria.

    ab109711 allows for isolation of Complex I from small amounts of tissue. This facilitates subsequent analysis of assembly state and activity. Thus the enzyme retains NADH-ferricyanide, NADH-CoQ1 and NADH hexaaminoruthenium reductase activities after isolation, and with added lipids it also shows significant rotenone sensitivity. Finally, the extent of post translational modifications including oxidative damage can be readily analyzed by proteomic approaches or antibody detection of these modifications. Uses for ab109711 include but are not limited to examining alterations of Complex I subunits in inherited mitochondrial diseases, Parkinson's disease, Alzheimer's disease, ALS, schizophrenia, and aging.

    Note: The immunocapture protocol for this kit requires Abcam detergent (lauryl maltoside, ab109857).

    Product supplied as a 6.25% slurry. For the 250 µg, this consists of 250 µg antibody conjugated to 25 µL beads in a volume of 400 µL.

Hello! Below is some more information about kit sizes. Please let me know if I can be of further assistance.

The kits size is based on antibody amount not the beads amount. 250ug refers to 25ul beads, 500ug to 50ul beads and 750ug to 75ul bead...

The lab let me know that both ab109711 and ab109798 are IP antibodies - unfortunately they do not work in WB. One can use it to pull down the whole complex I but needs to use other complex I subunit antibodies to blot the corresponding targets. Read More

To prepare 10% lauryl maltoside as the detergent for ab109711, pure water (deionized, nanopure etc) can be used. The lauryl maltoside should go into solution fairly easily. Gently turn in rotator, try not to shake it too much to prevent frothing.

In general, for well-prepped mitochondria, the ratio is 1-2 mg of mitochondria per 10 uL of beads. The optimal conditions will depend on the quality and source of the mitochondria so it’s very difficult to be specific, however. A good q...
