Biological activity was measured by its ability to produce hydrogen peroxide during the oxidation of benzylamine. The specific activity >16 pMoles/min/μg of VAP-1.
Reinheit
< 95 % by SDS-PAGE gel and HPLC analyses.
Endotoxin-Niveau
Endotoxin level is less than 0.1 ng per μg of VAP-1 (1 EU/μg).
AOC3
Spezies: Human
Wirt: Mammalian Cells
Recombinant
The purity of the protein is greater than 85 % as determined by SDS-PAGE and Coomassie blue staining.
As with any protein, exposing VAP-1 recombinant protein to repeated freeze / thaw cycles is not recommended. When working with proteins care should be taken to keep recombinant protein at a cool and stable temperature.
Lagerung
-20 °C
Informationen zur Lagerung
The recombinant protein is stable for at least 2 years from date of receipt at -20 °C. Reconstituted VAP-1 stable for at least 3 months when stored in working aliquots with a carrier protein at -20 °C.
VAP-1 is a type II membrane cell adhesion protein belonging to the copper/topaquinone oxidase family. It is primarily expressed on the high endothelial venules of peripheral lymph nodes and on hepatic endothelia. VAP-1 can catalyze the oxidative deamination of low molecular weight amines, and plays an important role in the migration of lymphocytes to inflamed tissue. Inhibition of VAP-1 can protect against inflammation related damage to certain injured tissues. Additionally, VAP-1 can function as a significant prognostic marker for certain cancers and cardiovascular diseases. Recombinant VAP-1 is a mixture of monomeric and disulfide linked homodimeric forms of a 737 amino acid polypeptide corresponding to amino acids 27 to 763 of the VAP-1 precursor.
