应用 Ab评论 说明
  • 应用说明
    ELISA: To give an A450nm = 1.0 using wells coated with human a1-antitrypsin at 5µg/mL andtetramethylbenzidine as the chromogen: 1/6400 – 1/12800
    The titres reported should be used as guidelines for determining the working dilution in the users system.
    The addition of Tween 20 (0.05 – 0.1%) to the conjugate diluent buffer is recommended to prevent non-specific binding in ELISA.
    It may also be advantageous in other assay systems.
  • 靶标

    • 功能
      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: 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).
    • 组织特异性
      Ubiquitous. Expressed in leukocytes and plasma.
    • 疾病相关
      Alpha-1-antitrypsin deficiency
    • 序列相似性
      Belongs to the serpin family.
    • 结构域
      The reactive center loop (RCL) extends out from the body of the protein and directs binding to the target protease. The protease cleaves the serpin at the reactive site within the RCL, establishing a covalent linkage between the carboxyl group of the serpin reactive site and the serine hydroxyl of the protease. The resulting inactive serpin-protease complex is highly stable.
    • 翻译后修饰
      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.
    • 细胞定位
      Secreted. Endoplasmic reticulum. The S and Z allele are not secreted effectively and accumulate intracellularly in the endoplasmic reticulum and Secreted, extracellular space, extracellular matrix.

    Thank you for your interest in our alpha 1 antitrypsin antibodies. I would recommend using ab7635 (goat antibody) as this antibody has been tested in ELISA, cross reacts with human, and is already HRP conjugated for your convenience. The antibody can ...
