potassium phosphate buffer table

Potassium phosphate buffer is often used in methods such as equilibrium dialysis high performance liquid chromatography (HPLC) and affinity capillary electrophoresis (ACE) for characterizing the binding of drugs and hormones with proteins or other ligands within the body In these experiments the buffer density is often approximated to be that of water and the concentrations of all reagents Elution buffer: 50 mM sodium phosphate 300 mM NaCl 250 mM imidazole pH 8 0 Note: Dynamic binding capacity will vary from protein to protein ** Maximum pressure test: Profinity IMAC resin packed in a 1 1 x 30 cm Amicon column to a bed height of 20 cm with 20 mM sodium phosphate buffer

All dissolution media used in this study (water and phosphate buffer pH 6 8) were degassed at 41 C in ultrasonic bath for 30 min prior to use A buffer potassium phosphate at pH 6 8 was prepared by adding 13 6 g of potassium dihydrogenphosphate and 224 mL of 0 2 mol L-1 sodium hydroxide in 2 0 L of

The sodium calcium magnesium potassium phosphate and chloride ions are present at concentrations similar to physiological concentrations in normal plasma Phoxilium is used to replace water and electrolytes removed during haemofiltration and haemodiafiltration or to serve as a suitable dialysate for use during continuous haemodiafiltration or continuous haemodialysis

The standard assay contained: 2 g G6PD 2 mM glucose-6-phosphate 1 mM NADP + 100 mM potassium phosphate buffer pH 7 4 (80C) The pH dependence of the enzyme was measured between 3 5 and 10 at 80C using either acetate potassium phosphate CHES or CAPS at a concentration of 100 mM each The substrate and cofactor specificities were examined using the

Subjects taking beta-blockers exhibited significantly higher salivary levels of sodium potassium and calcium whereas phosphate levels were not different between users and nonusers (Table 4) Phosphate levels were however increased in subjects treated with calcium channel blockers which also exhibited higher potassium levels In contrast users of angiotensin-modifying drugs (ACE inhibitors
