Protocols

* Product-specific protocol.

Specificity / Sensitivity

SDHA (D6J9M) XP® Rabbit mAb recognizes endogenous levels of total SDHA protein.

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Gly166 of human SDHA protein.

Background

Succinate dehydrogenase (SDH), also known as Complex II or succinate:quinone oxidoreductase, is a key component of the citric acid cycle and the electron transport chain (1). Specifically, it is involved in the oxidation of succinate (2). SDH consists of four subunits: SDHA, SDHB, SDHC, and SDHD (3). Research studies have shown that defects in SDHA cause complex II deficiency (2). In addition, investigators have observed reduction of SDHA in the striatum of patients with Huntington’s disease (3), and reduction of SDHB, SDHC, and SDHD in paragangliomas and phenochromocytomas (4,5).
