| Glutathione S-Transferase from E.coli, Recombinant | Glutathione S-transferases (GSTs), previously known as ligandins, comprise a family of eukaryotic and prokaryotic phase II metabolic isozymes best known for their ability to catalyze the conjugation of the reduced form of glutathione (GSH) to xenobiotic substrates for the purpose of detoxification. The GST family consists of three superfamilies:the cytosolic, mitochondrial, and microsomal--also known as MAPEG--proteins. Members of the GST superfamily are extremely diverse in amino acid sequence, and a large fraction of the sequences deposited in public databases are of unknown function. The Enzyme Function Initiative (EFI) is using GSTs as a model superfamily to iden.ferase. Mole weight: 26kDa. Activity: >20 units/mg. Stability: Store at 4°C if entire vial will be used within 2-4 weeks. Store, frozen at -20°C for longer periods of time. For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Avoid multiple freeze-thaw cycles. Form: Sterile Filtered clear solution in Phosphate Buffered Saline pH 7.4.

| Native Bovine 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. Thrombin in turn acts as a serine protease that converts soluble fibrinogen into insoluble strands of fibrin, as well as catalyzing many other coagulation-related reactions. Thrombin is the final coagulation protease in regard to hemostasis, promoting both procoagulant and anticoagulant effects. Applications: Thrombin is used for site specific cleavage of recombinant fusion proteins containing an accessible thrombin recognition site for removal of.Ia; E thrombin; β-thrombin; γ-thrombin.

| Native Human Cancer Antigen 125 | Cancer Antigen 125 (CA125) is a surface antigen associated with epithelial ovarian cancer. In serum, CA125 is associated with a high molecular weight glycoprotein. Published studies have indicated that elevated serum CA125 levels can be found in individuals with serious endometroid, clear-cell and undifferentiated ovarian carcinoma. Applications: Diagnostic controls; calibrators & standards; immunoassays; clinical chemistry; testing/assay validation; life science; elisa; blotting; manufacturing; tumor markers. Group: Others. Synonyms: MUCIN 16; muc16; CA-125; Cancer Antigen 125. Purity: > 95% (SDS-PAGE). Stability: 2 years. Storage: Store at -20°C. Form: Liquid in phosphate buffered saline, pH 7.4 with sucrose.

| Native Human Cancer Antigen 19-9 | Cancer Antigen 19-9 is a tumor marker elevated in blood of patients with carcinoma of the gastro-intestinal tract. Primarily used distinguishing pancreatic cancer from pancreatitis, CA 19-9 is not sufficiently specific for use as a cancer screening test. The specificity for pancreatic cancer increases with increasing levels, high levels showing a specificity of >97% for tumor presence. CA 19-9 can be elevated in many types of gastrointestinal cancer, such as colorectal cancer, esophageal cancer and hepatocellular carcinoma. A group of mucin type glycoprotein Sialosyl Lewis Antigens (SLA), such as CA19-9 and CA19-5, have come to be recognized as circulating cancer associated a.plications: Diagnostic controls; calibrators & standards; immunoassays; testing/assay validation; life science; validation studies; manufacturing; tumor markers. Group: Others. Synonyms: Tumor Marker 19-9; CA 19-9; Cancer Antigen 19-9; carbohydrate antigen 19-9; Sialylated Lewis (a) Antigen.

| Native Human Cancer Antigen 72-4 | Elevated CA 72-4 levels in serum and plasma have been reported in various malignant diseases including carcinomas of pancreas, stomach, gallbladder, colon, ovaries, cervix and endometrium. The highest diagnostic sensitivities, according to current studies, are found for carcinomas of the gastrointestinal tract and ovaries. Although some benign diseases such as rheumatic diseases or ovary cysts may also result in elevated levels of CA 72-4, clinical studies demonstrated diagnostic specificity of more than 95% for gastrointestinal and ovarian malignancies. There is a good correlation between CA 72-4 levels and tumor stage and size. CA 72-4 is the marker of choice for the therap.dependent marker for the therapeutic monitoring and follow-up care of ovarian cancer patients, in particular in CA 125 negative patients. Applications: Diagnostic controls; calibrators & standards; immunoassays; clinical chemistry; testing/assay validation; life science; elisa; blotting; manufacturing; tumor markers. Group: Others. Synonyms: CA 72-4; Cancer Antigen 72-4. Purity: > 90% (SDS-PAGE). Activity: > 100 kU/mL. Stability: 2 years. Appearance: Clear and colorless. Storage: Store at -20°C.

| Native Rat Angiotensin Converting Enzyme | Angiotensin-converting enzyme (EC 3.4.15.1), or "ACE" indirectly increases blood pressure by causing blood vessels to constrict. It does that by converting angiotensin I to angiotensin II, which constricts the vessels. For this reason, drugs known as ACE inhibitors are used to lower blood pressure. ACE, angiotensin I and angiotensin II are part of the renin-angiotensin system (RAS), which controls blood pressure by regulating the volume of fluids in the body. ACE is secreted in the lungs and kidneys by cells in the endothelium (inner layer) of blood vessels. Applications: Positive control. Group: Enzymes. Synonyms: ACE; Angiotensin Converting Enzyme; EC 3.4.15.1; dipeptid.1 M phosphate buffer and 300 mM NaCl at pH 8.3 at 37°C. Storage: Maintain at -20°C in undiluted aliquots for up to 6 months. Avoid repeated freeze/thaw cycles. Form: Liquid in 100 mM phosphate buffered saline, 150 mM NaCl, pH 7.4 with 0.2mM CHAPS. Source: Rat lung. Species: Rat.
