About SDHB
This tumor suppressor gene encodes the iron-sulfur protein subunit of the succinate dehydrogenase (SDH) enzyme complex which plays a critical role in mitochondria. The SDH enzyme complex is composed of four nuclear-encoded subunits. This enzyme complex converts succinate to fumarate which releases electrons as part of the citric acid cycle, and the enzyme complex additionally provides an attachment site for released electrons to be transferred to the oxidative phosphorylation pathway. The SDH enzyme complex plays a role in oxygen-related gene regulation through its conversion of succinate, which is an oxygen sensor that stabilizes the hypoxia-inducible factor 1 (HIF1) transcription factor. Sporadic and familial mutations in this gene result in paragangliomas, pheochromocytoma, and gastrointestinal stromal tumors, supporting a link between mitochondrial dysfunction and tumorigenesis. Mutations in this gene are also implicated in nuclear type 4 mitochondrial complex II deficiency. [provided by RefSeq, Jun 2022]

About DyLight 650
DyLight™ 650 is a red-emitting fluorophore that excited by the 640 nm laser and collected using a 670/30 nm bandpass filter. DyLight™ 650 has an excitation peak at 652 nm and an emission peak at 672 nm, and is spectrally similar to Alexa Fluor™ 647 and Cy5. DyLight™ 650 is most commonly used in flow cytometery and fluorescence microscopy applications.
