The nuclear pore complex (NPC) is a crucial cellular structure with a diameter of approximately 120 nanometers in vertebrates. Its channel varies from 5.2 nanometers in humans [14] to 10.7 nm in the frog Xenopus laevis, with a depth of roughly 45 nm. [15]
However, due to the often much larger image file size and a much bigger number of specimens in the experiments, in many cases it is needed to develop new 3D image registration software.BrainAligner [12] is software that has been used to automate the 3D deformable and nonlinear registration process using a reliable-landmark-matching strategy. It ...
Ribbon diagrams, also known as Richardson diagrams, are 3D schematic representations of protein structure and are one of the most common methods of protein depiction used today. The ribbon depicts the general course and organization of the protein backbone in 3D and serves as a visual framework for hanging details of the entire atomic structure ...
Moreover, live-cell imaging often employs special optical system and detector specifications. For example, ideally the microscopes used in live-cell imaging would have high signal-to-noise ratios, fast image acquisition rates to capture time-lapse video of extracellular events, and maintaining the long-term viability of the cells.

A phase contrast image (gray) is overlaid to visualize the cell contour. The scale bar is 2 μm. The Min System is a mechanism composed of three proteins MinC , MinD , and MinE used by E. coli as a means of properly localizing the septum prior to cell division .
Levinthal's paradox is a thought experiment in the field of computational protein structure prediction; protein folding seeks a stable energy configuration. An algorithmic search through all possible conformations to identify the minimum energy configuration (the native state) would take an immense duration; however in reality protein folding happens very quickly, even in the case of the most ...
The Chou–Fasman method predicts helices and strands in a similar fashion, first searching linearly through the sequence for a "nucleation" region of high helix or strand probability and then extending the region until a subsequent four-residue window carries a probability of less than 1.
Figure 3 - Reflectance signal as a function of wavelength. Bio-layer interferometry measures kinetics and biomolecular interactions on a basis of wave interference.To prepare for BLI analysis between two unique biomolecules, the ligand is first immobilized onto a bio compatible biosensor while the analyte is in solution.
