产品介绍 Thrombin is the final protease in the blood coagulation cascade and serves both pro- and anticoagulant functions through the cleavage of several targets. The ability of thrombin to specifically recognize a wide range of substrates derives from interactions which occur outside of the active site of thrombin. Thrombin possesses two anion binding exosites which mediate many of its interactions with cofactors and substrates, and although many structures of thrombin have been solved, few such interactions have been described in molecular detail. Glycosaminoglycan binding to exosite II of thrombin plays a major role in switching off the procoagulant functions of thrombin by mediating its irreversible inhibition by circulating serpins and by its binding to the endothelial cell surface receptor thrombomodulin.
Function : Thrombin is an active enzyme in the earliest steps of the blood clot formation, generated from its circulating inactive precursor prothrombin. Thrombin is a glycoprotein formed by two peptides chains of 36 and 259 amino acids linked by disulfure bonds. Three important sites have been identified on the surface of the enzyme: The catalytic site that confers to the molecule its serine protease activity, the exosite one responsible for the binding of the substrate (fibrinogen or thrombin receptor) and the exosite two responsible for the binding of antithrombin III and inactivation of thrombin. Gamma Thrombin is a proteolyzed form of Alpha Thrombin. Gamma Thrombin consists of four chains (A, B1, B5, B4) with a disulfide link between the A peptide and the B5 peptide.
Subunit : Heterodimer (named alpha-thrombin) of a light and a heavy chain; disulfide-linked. Forms a heterodimer with SERPINA5.
Subcellular Location : Secreted, extracellular space.
Tissue Specificity : Expressed by the liver and secreted in plasma.
Post-translational modifications : The gamma-carboxyglutamyl residues, which bind calcium ions, result from the carboxylation of glutamyl residues by a microsomal enzyme, the vitamin K-dependent carboxylase. The modified residues are necessary for the calcium-dependent interaction with a negatively charged phospholipid surface, which is essential for the conversion of prothrombin to thrombin.
N-glycosylated. N-glycan heterogeneity at Asn-121: Hex3HexNAc3 (minor), Hex4HexNAc3 (minor) and Hex5HexNAc4 (major). At Asn-143: Hex4HexNAc3 (minor) and Hex5HexNAc4 (major).
DISEASE : Factor II deficiency (FA2D) [MIM:613679]: A very rare blood coagulation disorder characterized by mucocutaneous bleeding symptoms. The severity of the bleeding manifestations correlates with blood factor II levels. Note=The disease is caused by mutations affecting the gene represented in this entry.
Ischemic stroke (ISCHSTR) [MIM:601367]: A stroke is an acute neurologic event leading to death of neural tissue of the brain and resulting in loss of motor, sensory and/or cognitive function. Ischemic strokes, resulting from vascular occlusion, is considered to be a highly complex disease consisting of a group of heterogeneous disorders with multiple genetic and environmental risk factors. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
Thrombophilia due to thrombin defect (THPH1) [MIM:188050]: A multifactorial disorder of hemostasis characterized by abnormal platelet aggregation in response to various agents and recurrent thrombi formation. Note=The disease is caused by mutations affecting the gene represented in this entry. A common genetic variation in the 3-prime untranslated region of the prothrombin gene is associated with elevated plasma prothrombin levels and an increased risk of venous thrombosis.
Pregnancy loss, recurrent, 2 (RPRGL2) [MIM:614390]: A common complication of pregnancy, resulting in spontaneous abortion before the fetus has reached viability. The term includes all miscarriages from the time of conception until 24 weeks of gestation. Recurrent pregnancy loss is defined as 3 or more consecutive spontaneous abortions. Note=Disease susceptibility is associated with variations affecting the gene represented in this entry.
Similarity : Belongs to the peptidase S1 family.
Contains 1 Gla (gamma-carboxy-glutamate) domain.
Contains 2 kringle domains.
Contains 1 peptidase S1 domain.

凝血酶(凝血因子II)重链抗体规格抗体的鉴定：
1）抗体的效价鉴定：不管是用于诊断还是用于治疗,制备抗体的目的都是要求较高效价。不同的抗原制备的抗体,要求的效价不一。鉴定效价的方法很多,包括有试管凝集反应,琼脂扩散试验,酶联免疫吸附试验等。常用的抗原所制备的抗体一般都有约成的鉴定效价的方法,以资比较。如制备抗抗体的效价,一般就采用琼脂扩散试验来鉴定。
2）抗体的特异性鉴定：抗体的特异性是指与相应抗原或近似抗原物质的识别能力。抗体的特异性高,它的识别能力就强。衡量特异性通常以交叉反应率来表示。交叉反应率可用竞争抑制试验测定。以不同浓度抗原和近似抗原分别做竞争抑制曲线,计算各自的结合率,求出各自在IC50时的浓度,并按公式计算交叉反应率。
如果所用抗原浓度IC50浓度为pg/管,而一些近似抗原物质的IC50浓度几乎是无穷大时,表示这一抗血清与其他抗原物质的交叉反应率近似为0,即该血清的特异性较好。
3）亲和力：是指抗体和抗原结合的牢固程度。亲和力的高低是由抗原分子的大小,抗体分子的结合位点与抗原决定簇之间立体构型的合适度决定的。有助于维持抗原抗体复合物稳定的分子间力有氢键,疏水键,侧链相反电荷基因的库仑力,范德华力和空间斥力。亲和力常以亲和常数K表示,K的单位是L/mol。抗体亲和力的测定对抗体的筛选,确定抗体的用途,验证抗体的均一性等均有重要意义。

凝血酶(凝血因子II)重链抗体规格实验原理 :
（1）特异性结合抗原：抗体本身不能直接溶解或杀伤带有特异抗原的靶细胞，通常需要补体或吞噬细胞等共同发挥效应以清除病原微生物或导致病理损伤。然而，抗体可通过与病毒或毒素的特异性结合，直接发挥中和病毒的作用。
（2）活补体：IgM、IgG1、IgG2和IgG3可通过经典途径激活补体，凝聚的IgA、IgG4和IgE可通过替代途径激活补体。
（3）结合细胞：不同类别的免疫球蛋白，可结合不同种的细胞，参与免疫应答。
（4）可通过胎盘及粘膜：免疫球蛋白G（IgG）能通过胎盘进入胎儿血流中，使胎儿形成自然被动
免疫。免疫球蛋白A（IgA）可通过消化道及呼吸道粘膜，是粘膜局部抗感染免疫的主要因素。
（5）具有抗原性：抗体分子是一种蛋白质，也具有刺机体产生免疫应答的性能。不同的免疫球蛋白分子，各具有不同的抗原性。
（6）抗体对理化因子的抵抗力与一般球蛋白相同：不耐热，60～70℃即被破坏。各种酶及能使蛋白质凝固变性的物质，均能破坏抗体的作用。抗体可被中性盐类沉淀。在生产上常可用硫酸铵或硫酸钠从免疫血清中沉淀出含有抗体的球蛋白，再经透析法将其纯化。
