3,4,5-三咖啡酰奎宁酸使用说明书不能直接用于人体,出库的产品全部经过严格的检测,保证质量。标准品/对照品一般用于鉴别、检查和含量 (或效价)测定。对于鉴别来说,只要确认未混淆标准物质 即可,而检查和含量测定则不同,大部分检查项目和含量测定项目均有明确的标准。这就要求在进行检验时要控制实验误差,在进行标准物质称量时未严格按照药典等标准要求进行。
proteolytic activity against insulin and plasmin.
Short peptide from AAT (SPAAT) is a reversible chymotrypsin inhibitor. It also inhibits elastase, but not trypsin. Its major physiological function is the protection of the lower respiratory tract against proteolytic destruction by human leukocyte elastase (HLE).
Subcellular Location : Secreted.
Short peptide from AAT: Secreted, extracellular space, extracellular matrix.
Tissue Specificity : Plasma.
Post-translatio
nal modifications : N-glycosylated. Differential glycosylation produces a number of isoforms. N-l
inked glycan at Asn-107 is alternatively di-antennary, tri-antennary or tetra-antennary. The glycan at Asn-70 is di-antennary with trace amounts of tri-antennary. Glycan at Asn-271 is exclusively di-antennary. Structure of glycans at Asn-70 and Asn-271 is Hex5HexNAc4. The structure of the antennae is Neuc(alpha1-6)Gal(beta1-4)GlcNAc attached to the core structure Man(alpha1-6)[Man(alpha1-3)]Man(beta1-4)GlcNAc(beta1-4)GlcNAc. Some antennae are fucosylated, which forms a Lewis-X determinant.
Proteolytic processing may yield the truncated form that ranges from Asp-30 to Lys-418.
DISEASE : Defects in SERPINA1 are the cause of alpha-1-antitrypsin deficiency (A1ATD) [MIM:613490]. A disorder whose most common manifestation is emphysema, which becomes evident by the third to fourth decade. A less common manifestation of the deficiency is liver disease, which occurs in children and adults, and may result in cirrhosis and liver failure. Enviro
nmental factors, particularly cigarette smoking, greatly increase the risk of emphysema at an earlier age.
Similarity : Belo
ngs to the serpin family.
