S UMMARY OF M ETHOD : This is an inhibition assay, pantothenic acid binds to poly (A)-binding protein ( PABP) and inhibits the interaction between PABP and immobilized PA on sensor chip. PABP binds to PA on sensor chip and generates surface plasmon resonance (SPR) response which is inversely related to PA level in sample. Using a simple sample preparation, Vitamin B5 (Pantothenic Acid) can be determined using SPR that uses the specificity of the ligand binding protein interaction to determine the concentration Pantothenic Acid. G ENERAL C OMMENTS : This method is a quick assay, more time-efficient than micro-assay and chromatography based methods. Due to the use of proprietary instrumentation and kits, it limits the number of vendors a laboratory could use to purchase. The manuscript indicates the costs are less than HPLC and MS instrumentation, but no actual costs are used. There is limited applicability of the instrument. P ROS /S TRENGTHS : This method is very fast and there is a quick determination of B5 in specified matrices versus legacy microbiological methods. C ONS /W EAKNESSES : It is a proprietary assay and it has a limited scope. The method only uses specific instrumentation and kits. It was also noted that there are high RSDs in some of the matrices.
