Thank you very much for your reply it was very usefull!!
I am also wondering whether I can use frozen human cells on your'Complex IV human enzyme activity microplate assay kit' (ab109909) or'Complex IV human specific activity microplate assay kit' (ab109910)?
Asked on Jun 01 2012
I now have further information to share with you in regards to the kits Complex IV human enzyme activity microplate assay kit (ab109909)andComplex IV human specific activity microplate assay kit (ab109910).
As with the Complex IV human enzyme dipstick (ab109876) which you were interested in, these kits are also compatible with the sort of sample you are hoping to use. You could make a pellet of cells and freeze them at -80C as a dry pellet. There is in fact no need to freeze the cells viable.
What we recommend is to do the activity assay on the day the cells are treated with detergent, otherwise they may run the risk of degradation of the sample while stored in the provided detergent at -80C.
I hope this information has been of help. If you have any further information please do not hesitate to contact us again.
