Source: Ricardo Mejia-Alvarez and Hussam Hikmat Jabbar, Department of Mechanical Engineering, Michigan State University, East Lansing, MI The purpose of this experiment is to demonstrate the application of the energy conservation equation to determine the performance of a flow system. To this end, the energy equation for steady, incompressible flow is applied to a short pipe with a gate valve. The gate valve is then gradually closed and its influence on flow conditions is characterized. In...

Biochemical assays with recombinant human MHC II molecules can provide rapid, quantitative insights into immunogenic epitope identification, deletion, or design. Here, a peptide-MHC II binding assay scaled to 384-well plates is described. This cost effective format should prove useful in the fields of protein deimmunization and vaccine design and development.

Source: Nicholas Timmons, Asantha Cooray, PhD, Department of Physics & Astronomy, School of Physical Sciences, University of California, Irvine, CA The goal of this experiment is to test the concept of the conservation of momentum. By setting up a surface with very little friction, collisions between moving objects can be studied, including their initial and final momenta. The conservation of momentum is one of the most important laws in physics. When something is conserved in physics, the...

Conserved Binding Sites

Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function. Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally analyses the...
FAQs
Sequence comparisons reveal whether an immune-recognized region remains similar across pathogen strains, variants, or related species. Regions with limited sequence change are treated as stable candidates, whereas highly variable regions may be less dependable for broad targeting. This contrast helps researchers connect pathogen diversity with the likelihood that a selected epitope will remain represented across the sequences examined.
B-cell and T-cell epitopes provide complementary immune targets, so they should be mapped separately when interpreting conservation. A conserved sequence can support prioritization, but sequence change within an epitope may alter immune recognition, especially when the analysis is linked to experimentally defined or predicted epitopes. Distinguishing these epitope types clarifies which immune response a candidate is intended to support.
High sequence conservation is useful evidence of antigenic stability, but it is not identical to a direct measurement of immune recognition. Epitope conservation analysis links sequence similarity with antigenic stability to identify promising targets, while experimental epitope definitions can add immune-specific context. This distinction prevents researchers from treating a conserved sequence alone as proof of broad protection.
A typical workflow begins by assembling protein or genome sequences from the strains, variants, or related species being compared. Researchers then map predicted or experimentally defined B-cell and T-cell epitopes onto those sequences, measure conservation across corresponding regions, and classify targets according to their stability or variability. The resulting comparison supports focused evaluation of candidate immune targets.
The sequence set defines the comparison's scope and interpretation. Researchers may examine strains, variants, or related species, then assess how consistently each mapped epitope appears across that selected group. A region can therefore look stable within one collection yet show greater variation when additional pathogen diversity is included. This scope matters when prioritizing vaccine or diagnostic targets.
In infection research, the results can guide several decisions. Conserved epitopes may be prioritized for broadly protective vaccine design, while conservation of diagnostic targets can help assess whether tests remain reliable as pathogens evolve. Comparing variants also supports surveillance by highlighting immune-relevant changes and helps researchers interpret how mutations could affect recognition. Thus, the method connects sequence monitoring with practical immunological planning.
