Calcium chloride ≥99%, white powder cell culture reagent

Supplier: MP Biomedicals

Calcium Chloride is a salt of calcium and chloride. It behaves as a typical ionic halide, and is solid at room temperature.
Calcium chloride is a commonly used reagent in biochemistry. It plays important roles in many biological processes, including signal transduction, muscle contraction, and maintenance of cell membrane and cell wall stability. Calcium chloride is used in the preparation and transformation of competent E. coli and in the transfection of eukaryotic cells with either plasmid DNA or high molecular weight genomic DNA. It has been used in the stabilization and two dimensional crystallization of the NADH-ubiquinone oxidoreductase (complex I) from Escherichia coli. It is also used as a dessicant, coagulant in rubber manufacturing and as an accelerator in the concrete industry.

Cell culture media, high growth enhancement medium, MP Biomedicals

Supplier: MP Biomedicals

High Growth Enhancement Medium is a modification of DMEM in which 3,6 g/L fructose is substituted for glucose, resulting in better pH control and higher cell yields. Fructose is metabolised slower than glucose, resulting in slower acid build up. This media is recommended for the growth and support of cells on microcarrier matrices.

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.

Methacholine chloride ≥98%, white powder

Supplier: MP Biomedicals

Methacholine chloride is a cholinergic agonist and parasympathomimetic bronchoconstrictor. A metabolically stable analog of acetylcholine. Its ability to constrict airway smooth muscle is used to assess bronchial reactivity in the laboratory and clinically.
Methacholine is primarily used to diagnose bronchial hyperreactivity, which is the hallmark of asthma and also occurs in chronic obstructive pulmonary disease. Acetyl-β-methylcholine (methacholine), an analog of acetylcholine, is use as a receptor agonist to study processes such as airway hyperresponsiveness associated with asthma.
Metabolically stable analog of acetylcholine; muscarinic agonist. Its ability to constrict airway smooth muscle is used to assess bronchial reactivity in the laboratory and clinically.
