SILu^™Prot APOD, Apolipoprotein D human

Apolipoprotein D is a member of the Apolipoprotein family. Unlike other lipoproteins, which are mainly produced in the liver, apolipoprotein D is mainly produced in the brain and testes. It was found to be a putative biomarker of androgen receptor function in androgen insensitivity syndrome, the most common cause of disorders of sex development. Apolipoprotein D is associated with neurological disorders and nerve injury, especially related to myelin sheath. It was shown to be elevated in a rat model of stroke, and is elevated in patients with schizophrenia, bipolar disorder, and Alzheimer′s disease.

SILu^™Prot APOD is a recombinant, stable isotope-labeled human APOD which incorporates [¹³C₆, ¹⁵N₄]-Arginine and [¹³C₆, ¹⁵N₂]-Lysine. Expressed in human 293 cells, it is designed to be used as an internal standard for bioanalysis of APOD in mass-spectrometry. SILu^™Prot APOD is a protein of 189 amino acids (including a C-terminal polyhistidine and tag), with a calculated molecular mass of 21.8 kDa.
