Human α-Thrombin (EC 3.4.21.5; Human Alpha Thrombin) (Lyophilized) is a terminal serine protease in the coagulation cascade, as well as a potent physiological platelet agonist and fibrin-generating enzyme in vivo. Human α-Thrombin catalyzes the conversion of fibrinogen to fibrin for blood clot formation, and activates platelet aggregation by cleaving the protease-activated receptors PAR1 (major) (K_d = 1 nM) and PAR4 (minor) on the platelet surface to expose tethered ligands. Human α-Thrombin also amplifies coagulation via positive feedback by activating coagulation factors V, VIII, XI (FV/FVIII/FXI), and switches to activate protein C to exert anticoagulant effects after binding to thrombomodulin.
This product is in a freeze-dried form.

Human UGT2B7 is a UDP-glucuronosyltransferase isoform. Human UGT2B7 catalyzes the glucuronidation of Clopidogrel carboxylic acid (HY-141749A), Chloramphenicol (HY-B0239), and Morphine. Human UGT2B7 can be used in studies related to acute coronary syndrome and thrombus-induced events.

Sortase A, S. aureus (SrtA), a transpeptidase enzyme is present in many Gram-positive bacteria and helps in the recruitment of the cell surface proteins. Sortase A, S. aureus plays an important part in ligation of various molecules on the cell surfaces.

Cathepsin B, Bovine spleen is a cysteine protease and is involved in multiple kinds of programmed cell death (including apoptosis, pyroptosis, ferroptosis, necroptosis, and autophagic cell death).

γ-glutamyltransferase, Porcine kidney (GGT, Porcine kidney) is an enzyme located on the outer surface of the cell membrane. γ-glutamyltransferase, Porcine kidney maintains the physiological concentration of cytoplasmic glutathione and the cell's defense against oxidative stress by cleaving extracellular glutathione and increasing the availability of amino acids. γ-glutamyltransferase, Porcine kidney is used for pancreatic cancer research.

Tenecteplase (TNK-tPA) is a modified tissue plasminogen activator. Tenecteplase is a recombinant human tissue plasminogen activator (rt-PA) that has been bioengineered to produce mutations in three gene loci. Tenecteplase (TNK-tPA) can be used in the study of acute ischemic stroke.

Glycerol kinase, microorganism (GyK) acts as a NR4A1 inhibitor with enzymatic activity. It directly binds to and inhibits the transcription factor NR4A1, thereby negatively regulating hepatic gluconeogenesis and reducing blood glucose levels. Glycerol kinase, microorganism positively regulates UCP1 expression via partial dependence on the β-adrenergic receptor-cAMP-CREB pathway, promotes browning of white adipose tissue and thermogenesis, and further modulates intracellular fatty acid composition and energy metabolism. In diabetic mouse models, overexpression of Glycerol kinase effectively antagonizes NR4A1-induced hyperglycemia, demonstrating potential for improving glucose homeostasis. Glycerol kinase, microorganism can be used for studies on diabetes and obesity.

Angiotensin-converting enzyme (Kininase II) is a dicarboxypeptidase, it converts inactive Angiotensin I (Ang I) to active Ang II and degrades active bradykinin (BK). Angiotensin-converting enzyme is a potent vasoconstrictor, is often used in biochemical studies.

Acetate kinase (ACK) is an enzyme widely distributed in bacteria and archaea. In the presence of ATP and divalent cations, it catalyzes the phosphorylation of acetate and promotes the production of acetyl-CoA. Often used in biochemical research.

Creatine Kinase (CPK/CK), Bovine Heart (CK) is a creatine kinase derived from bovine heart. Creatine Kinase (CPK/CK), Bovine Heart catalyzes the reversible phosphate transfer reaction between phosphocreatine and ADP, and is widely used in myocardial energy metabolism research and quality control of clinical biochemical tests.

Dornase alfa (rhDNase) is a recombinant human deoxyribonuclease I (rhDNase) that can specifically degrade extracellular DNA. Dornase alfa catalyzes the cleavage of DNA released by neutrophils in respiratory mucus, reduces sputum viscosity, thereby improving mucus clearance efficiency, reducing airway obstruction and alleviating inflammatory responses. Dornase alfa can be used to improve lung function (such as FEV_1) in cystic fibrosis (CF), reduce the risk of acute pulmonary exacerbations, and has good in vivo tolerability. Dornase alfa acts locally on the respiratory tract through aerosol inhalation, specifically improving the high viscosity of mucus caused by DNA accumulation and related respiratory symptoms.

Lumbokinase attenuates myocardial ischemia-reperfusion (I-R) injury through the activation of Sirt1 signaling, and thus enhances autophagic flux and reduces I-R-induced oxidative damage, inflammation and apoptosis.

Sortase A, S. aureus (non-Ca²⁺-dependent), a transpeptidase enzyme is present in many Gram-positive bacteria and helps in the recruitment of the cell surface proteins. Sortase A, S. aureus (non-Ca²⁺-dependent) plays an important part in ligation of various molecules on the cell surfaces.

Serratiopeptidase (Brasan; Dasen) is an orally active zinc-containing metalloprotease belonging to the serralysin family. Serratiopeptidase reduces the release of inflammatory mediators such as prostaglandins, thromboxanes and interleukins by inhibiting COX, thereby relieving pain, swelling and redness. Serratiopeptidase exhibits antibiofilm, mucolytic and wound-healing activities. As a serine protease, Serratiopeptidase has the ability to dissolve blood clots, fibrin and atherosclerotic plaques. Serratiopeptidase degrades amyloid fibrils and has potential anti-Alzheimer's effects. Serratiopeptidase shows cytotoxicity against colon cancer cells.
