Describe the principle of either ion exchange or affinity chromatography. Why does the uncertainty principle make it impossible to predict a trajectory for the electron? Explain the concept of surface tension. Explain the concept of polarizability. Describe briefly why the study of electr...
Describe the fundamental difference between ion-exchange and size-exclusion chromatography. What is the difference between LUMO and HOMO? Discuss the difference between 'salting in' and 'salting out' and explain why these Describe quenching, in regards to fluorimetry. ...
Describe the fundamental difference between ion-exchange and size-exclusion chromatography. Write definitions to distinguish between the terms accuracy and precision. Explain the difference between repeatability and reproducibility. What is the significance of points X and Y on the figure? Define ...
However, the most widely used is ultra-high-performance liquid chromatography coupled to triple quadrupole mass spectrometry (UHPLC-QqQ-MS/MS) due to its high sensitivity, selectivity, and high throughput [28]. The phenolic compounds detected in propolis samples were hydroxybenzoic acids (HBAs) and...

For a complete buffer exchange, liposomes were snap frozen and thawed at room temperature, and the freeze-thaw cycles were repeated two times. The liposomes were homogenized by repeated extrusion through a 400 nm polycarbonate filter, using the Liposofast LF-50 (Avestin inc, Mannheim, ...
AncFMO1 and AltAncFMO1 were purified with a metal-ion affinity chromatography that bound the histidine tag attached to the N-terminal part of the fused SUMO protein. The cell-free extract was applied to the column and washed with increasing concentrations of imidazole. Buffer B contained 250-...
In those few transgenic animal studies where the abnormal development of semilunar valves and the pathological state of ascending aorta were both in focus, the impaired signal exchange between endocardial cushion, NCC and SHF gave rise to the defective development of the ascending aorta in parallel...
Explain the principle of gaseous exchange in the lungs. Explain the sliding filament and ratchet mechanism in skeletal muscle contraction, accounting for the role of calcium in contraction and relaxation. Discuss and describe the structure and function of the cell and its organelles. How does an en...
A process by which proteins can be separated from a mixture is known as chromatography. This process consists of two phases: the mobile (liquid) and the stationary (solid) phases. Different types of chromatography are used in laboratories, such as paper chromatography, affinity chromatography, ...
