SILu™Prot APOD, Apolipoprotein D human
SIGMA/MSST0061 - recombinant, expressed in HEK 293 cells, SIL MS Protein Standard, 13C and 15N-labeled
Synonym: Apo-D; ApoD
Product Type: Chemical
SILuProt products are stable isotope-labeled full length proteins designed to be used as mass spectrometry internal standards for quantitative proteomics. Introduction of an internal SILuProt standard at the beginning of the MS workflow minimizes variations in quantification due to protein extraction, fractionation, enrichment, proteolysis and analysis

| Biochem/physiol Actions: | 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. |
| General description: | 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. |
