Creatinine, the end product of creatine catabolism is a normal constituent of urine; daily output about 25 mg/kg body weight. The increased amounts in the urine are typically associated with substantially impaired renal function. Also found together with creatine in muscle tissues and blood. It reacts with picric acid under alkaline conditions to form a Janovski complex. The rate of formation of the colored complex, measured at 480-520 nm is proportional to the creatinine concentration.
Creatinine is a useful marker for normalizing levels of other molecules found in urine and the altered creatinine levels may be associated with conditions that result in decreased renal blood flow, such as diabetes and cardiovascular disease.

Trimethoprim is an antibacterial agent; a specific inhibitor of formylation; a dihydrofolate reductase inhibitor.
Trimethoprim is primarily used as an antibacterial agent. It has dihydrofolate reductase inhibitor activity with selectivity for the prokaryote enzyme. It is used to treat urinary tract infections, mild acute prostatitis, recurrent cystitis, asymptomatic bacteriuria during pregnancy and respiratory tract infections.
The combination of trimethoprim and sulfamethoxazole interferes with the cellular metabolism of folic acid in the bacterial cell by blocking the biosynthesis of nucleotides. Trimethoprim binds to dihydrofolate reductase and inhibits the reduction of dihydrofolic acid (DHF) to tetrahydrofolic acid (THF). THF is an essential precursor in the thymidine synthesis pathway and interference with this pathway inhibits bacterial DNA synthesis.

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
