  • Fibrinogen from Bovine

    MP Biomedicals

    Fibrinogen has been used in studies of haemostatic therapy in surgical and massive trauma patients. These studies have shown that fibrinogen may prove to be more superior in stopping blood loss when compared to using fresh frozen plasma (FFP). Fibrinogen is a blood protein that is involved in…

  • Pancreatin is a digestive enzyme produced by the pancreas and delivered to the small intestine for the hydrolysis of complex nutrients. Pancreatin contains enzymatic components including trypsin, amylase and lipase, ribonuclease, and protease, produced by the exocrine cells of the porcine pancreas.…

  • Lactulose

    MP Biomedicals

    Lactulose is used as a test of small intestine bacterial overgrowth (SIBO). Lactulose is used in the treatment of chronic constipation. It is useful in treating the hyperammonemia caused by hepatic encephalopathy, because it helps "draw out" ammonia from the body. Lactulose is also a food…

  • Peptone a water-soluble product, is a mixture of polypeptides and amino acids formed by the partial hydrolysis of protein. Peptone is produced from porcine and/or bovine tissues. The tissues are digested enzymatically to create small peptides and then spray dried. Peptone is used in culture…

  • Bovine γ-globulin is a plasma protein fraction rich in antibodies. Bovine γ-globulin has been used as an immunological challenge in studies of mechanisms of immunotolerance. Bovine γ-globulins were used to study the constituents and pH changes in protein rich hyaluronan…
