| 产品介绍 | Alpha-1-antitrypsin is a protease inhibitor, deficiency of which is associated with emphysema and liver disease. The protein is encoded by a gene (PI) located on the distal long arm of chromosome 14. Function: Inhibitor of serine proteases. Its primary target is elastase, but it also has a moderate affinity for plasmin and thrombin. Irreversibly inhibits trypsin, chymotrypsin and plasminogen activator. The aberrant form inhibits insulin-induced NO synthesis in platelets, decreases coagulation time and has 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-translational modifications: N-glycosylated. Differential glycosylation produces a number of isoforms. N-linked 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 Neu5Ac(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. Environmental factors, particularly cigarette smoking, greatly increase the risk of emphysema at an earlier age. Similarity: Belongs to the serpin family.

文献和实验α -抗胰蛋白酶（α1 -antitrypsin,α1 AT或AAT），是具有蛋白酶抑制作用的一种急性时相反应蛋白，分子量为5.5万，P1 值4.8，含有10%-12%糖。在醋酸纤维薄膜或琼脂糖电泳中泳动于α1 区带，是这一区带的主要组分。区带中的另2个主要组分；α1 -酸性糖蛋白含糖量特别高，α1 -脂蛋白含脂类特别高，因此蛋白质的染色都很浅。作为蛋白酶的抑制物，它不仅作用于胰蛋白酶，同时也作用于糜蛋白酶、尿激酶、肾素、胶原酶、弹性蛋白酶、纤溶酶和凝血酶等。AAT占血清
双抗体夹心ELISA法检测待测样品sTNF- α 含量 【基本原理】 选用两株针对TNF-α分子不同位点的单克隆抗体，即McAb1 （包被抗体）与McAb2 （酶标抗体）。先用McAb1 包被固相载体，使待测sTNF-α与之特异性结合，然后再加入辣根过氧化物酶（HRP）标记的McAb2 ，则形成McAb1 -sTNF-α -HRP标记McAb2 复合物，再加入HRP底物，则酶催化底物显色，测定样品与标准品光密度值（即OD值），绘制标准曲线，即可从标准曲线中
实验试剂 1. 包被抗体McAb1 ：使用时用包被液作适当稀释(如1：100)。 2. 酶标抗体McAb2 ：以辣根过氧化物酶(HRP)标记。使用时用稀释液作适当稀释，其稀释度根据预试验结果而定。 3. rhuTNF-α标准品：已知含量的rhuTNF-(10ng/ml)，使用时用稀释液作倍比稀释成7个浓度：5 ng/ml，2.5 ng/ml，1.25 ng/ml，625pg/ml，312 pg/ml，156 pg/ml
