Intrinsic factor (from porcine pyloric mucous lining), powder

Supplier: MP Biomedicals

Description: Preparation Method: MP Intrinsic Factor is produced from the pylorus mucous membrane of the pig, of which only a small part is used. Only the part which, according to histological examinations has proved to have a high content of Intrinsic Factor, is used.
Applications: Intrinsic Factor is used in the treatment not only of classical pernicious anaemia, but also in the treatment of other macrocytic anaemias, where it replaces the Intrinsic Factor which may be lacking in the patient's own gastric juice. In this way Intrinsic Factor is recommended against anaemias that appear 6 to 12 months after serious gastric operations, and against anaemias that are secondary effects of the treatment with certain medicines, e.g. against epilepsy. However, the dietetic use in multi-vitamin preparations is of the greatest importance. In older people there has been observed a degeneration of the gastric mucous membrane, whose secretion of Intrinsic Factor is insufficient to ensure the resorption of the necessary quantity of B-12 from their diet. In order to delay this development it is useful to prescribe a small quantity of Intrinsic Factor with B-12 and other vitamins to these patients.
Product Description: Intrinsic factor is a glucoprotein extracted from the pylorus part of the gastric mucous membrane. Its presence is considered necessary for the absorption of Vitamin B-12.
Unit Definition: The activity is normally indicated in Coli units, the number of which are proportional to the binding power of the substance to Vitamin B-12.

Application Areas: Absorption of vitamin B12
Product Type: Proteins, Enzymes & Peptides
Presentation: Tan Powder
Foreign activity: Salmonella=Negative, E. coli=Negative
NOTES: Standard Plate Count <1000/g
Solubility: Slightly soluble in toluene; practically insoluble in water.
Storage & Handling: -20°C
