- I (Increasing energy), III (Gamma rays) and VI (Infrared) (correct)
High Performance/Pressure Liquid Chromatography (HPLC) can be used either in normal phase or reverse phase. Which one of the statements below is incorrect?
High Performance/Pressure Liquid Chromatography (HPLC) can be used either in normal phase or reverse phase. Which one of the statements below is incorrect?
- Reverse phase HPLC mobile phase is usually a mixture of water and organic solvents
- In reverse phase HPLC, the bond strength between analyte and stationary phase is inversely proportional to the analyte hydrophobicity (correct)
- In reverse phase HPLC, adjusting the pH of the mobile phase will change the hydrophobicity of the analytes
- In normal phase HPLC, the analyte separation is based on the degree of polar-polar interactions between analyte and stationary phase
Which one of the statements (below) regarding discontinuous gel electrophoresis of proteins is incorrect?
Which one of the statements (below) regarding discontinuous gel electrophoresis of proteins is incorrect?
- The proteins are separated on the basis of size
- The electrical current is applied in cycles of (x) minutes on, (x) minutes off (repeat) – the value of x depends on the molecular weight of the largest protein (correct)
- The samples are loaded into stacking gel wells
- The proteins concentrate at the stacking gel/running gel boundary when the electrical current is applied
