Glutamine
Supplier: Biowest
L-glutamine is an essential amino acid required by virtually all mammalian and insect cells grown in culture. It is a crucial component of many cell culture media and serves as a major energy source for cells in culture. L-glutamine is very stable as a dry powder and as a frozen solution. However, in liquid media or stock solutions, L-glutamine can degrade relatively rapidly. L-glutamine is also more labile in cell culture solution than other amino acids.

Creatinine, anhydrous 98.5-102%, white powder
Supplier: MP Biomedicals
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, white powder
Supplier: MP Biomedicals
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.
