SDHA Protein, Human (His)

SDHA Protein, Human (His) is the recombinant human-derived SDHA protein, expressed by E. coli, with C-6*His tag.

SDHA is the flavoprotein (FP) subunit of succinate dehydrogenase (SDH), which participates in complex II of the mitochondrial electron transport chain and is responsible for transferring electrons from succinate to ubiquinone (coenzyme Q). SDH also oxidizes malate to the non-canonical enol form of oxaloacetate, enol-oxaloacetate (by similar). Enol-oxaloacetate, a potent inhibitor of succinate dehydrogenase activity, can be further isomerized into keto-oxaloacetate (by similar). Additionally, SDHA can function as a tumor suppressor.

Approximately 75 kDa, based on SDS-PAGE under reducing conditions.

Greater than 95% as determined by reducing SDS-PAGE.

Lyophilized powder.

Lyophilized from a 0.22 μm filtered solution of PBS, pH 7.4, 8% trehalose.

<1 EU/μg, determined by LAL method.

It is not recommended to reconstitute to a concentration less than 100 μg/mL in ddH₂O.

Stored at -20°C for 2 years from date of receipt. After reconstitution, it is stable at 4°C for 1 week or -20°C for longer (with carrier protein). It is recommended to freeze aliquots at -20°C or -80°C for extended storage.

Room temperature in continental US; may vary elsewhere.
