| Native Human Leukocyte Esterase, Unsonicated | Leukocyte Esterase is used in a urine test for presence of white blood cells abnormalities associated with infection. Urine tests reveal the presence of granulocyte esterases. The esterases cleave a derivatized pyrazole amino acid ester to liberate derivatized hydroxy pyrazole. This pyrazole then reacts with a diazonium salt to produce a purple color. White blood cells in the urine usually indicate a urinary tract infection. Human leukocytes esterase test detects human esterase, an enzyme released by white blood cells. Human White blood cells are produced in the bone marrow and help to defend the body against infectious disease and foreign materials as part of the immun...ence of white blood cells and other abnormalities associated with infection. Applications: Diagnostic controls, calibrators & standards; immunoassays; clinical chemistry; testing/assay validation; life science; validation studies; characterization; manufacturing; urinalysis.

| Native Porcine Creatine Kinase MM | Creatine kinase, muscle also known as CKM is a creatine kinase that in humans is encoded by the CKM gene. In the figure to the right, the crystal structure of the muscle-type M-CK monomer is shown. In vivo, two such monomers arrange symmetrically to form the active MM-CK enzyme. In heart, in addition to the MM-CK homodimer, also the heterodimer MB-CK consisting of one muscle (M-CK) and one brain-type (B-CK) subunit is expressed. The latter may be an important serum marker for myocardial infarction, if released from damaged myocardial cells into the blood where it can be detected by clinical chemistry. Applications: Diagnostic controls, calibrators & standards; clinical chemistry; testing/assay validation; life science; manufacturing. Group: Enzymes. Synonyms: CKM; creatine kinase, muscle; CKMM; creatine kinase M-type; creatine kinase-M; creatine kinase M chain; M-CK; MM-CK. Purity: > 90% (SDS-PAGE). CK. Mole weight: 43 kDa. Stability: 2 years.

| Native Porcine Thrombin | Thrombin is a serine protease that in humans is encoded by the F2 gene. Prothrombin (coagulation factor II) is proteolytically cleaved to form thrombin in the coagulation cascade, which ultimately results in the reduction of blood loss.
