Product overview
Aminohippuric acid Assay Kit (ab204725) utilizes a 96-well format in which p-Aminohippuric acid (PAH) reacts with Dimethylaminocinnamaldehyde (DACA) which gives a strongly colored derivative at OD = 550 nm. The amounts of PAH in urine and plasma can easily be quantified with this product.

Notes
p-Aminohippuric acid (PAH) is a derivative of hippuric acid and useful as a diagnostic agent for the measurement of renal plasma flow. About 20-30% is completely filtered by the glomerulus and not readsorbed by the tubules. The remainder which bypasses the glomerulus and enters the tubules is completely secreted. At low doses, PAH is almost completely removed with one-pass through the kidneys. Hence, the venous concentration of PAH is close to zero and PAH has been used to determine the effective renal plasma flow (eRPF) from the plasma. The venous concentration is usually
eRPF = ([PAH]U/[PAH]P) x Urine Volume
