Brief Description & Uses

100 g of monoclonal antibody reactive against the 26 kDa COX (Complex IV) subunit II. MS405 also labels COX II in immunocytochemical applications. Isolated mitochondria are available from several species for use as control samples. To see the complete list of control samples available from MitoSciences, click here. Variations in the synthesis of cytochrome c oxidase subunits from the two genomes (mitochondrial and nuclear) have been described as markers for several cancers including those of the prostate, and thyroid. Additionally this ratio has been reported to identify areas of the brain damaged in Alzheimer’s disease and also to relate to the overall regulation of mitochondrial biogenesis in exercise and diet. To examine this ratio in immunocytochemistry we offer two mAbs against mitochondrially encoded subunits I and II (MS404 and MS405, respectively) and mAbs against two nuclear encoded subunits IV and Va (MS408 and MS409, respectively). The latter two are retained in mitochondria exhibiting heterolpasmy or mosaicism of altered mtDNA transcription e.g. in anti-retroviral therapy. Therefore an immunocytochemical study using a combination of subunits I or II alongside IV or Va could reveal changes in the levels of mtDNA or mtDNA encoded proteins.
