Several pathological biomarkers cannot be easily detected by current techniques because of their low concentration in biological fluids, the presence of degrading enzymes, and large amounts of high molecular weight proteins. Chemically functionalized hydrogel nanoparticles can harvest, preserve and concentrate low abundance proteins enabling the detection of previously undetectable biomarkers.

Here, we describe a method that combines in situ MHC-tetramer staining with immunohistochemistry to determine localization, phenotype, and quantity of antigen-specific T cells in tissues. This protocol is used to determine the spatial and phenotypic characteristics of antigen-specific CD8 T cells relative to other cell type and structures in tissues.
FAQs
A relatively slow catalytic rate limits how quickly individual Rubisco molecules can support carbon fixation. Producing a large amount of the enzyme can help an organism maintain sufficient carbon fixation despite that limitation. Consequently, abundance provides an important indicator of how much biochemical capacity a plant, alga, or cyanobacterium allocates to initiating photosynthetic carbon fixation.
Rubisco can react with oxygen as well as carbon dioxide. This alternative reaction reduces the certainty that every enzyme encounter will contribute to carbon fixation, particularly when oxygen is available. Cells may therefore produce Rubisco in large quantities to support sufficient carbon fixation despite both its relatively slow catalytic rate and its ability to use oxygen.
Rubisco abundance helps researchers examine how much cellular investment is directed toward the enzyme that initiates carbon fixation. Because the measurement can be interpreted alongside nitrogen allocation, it connects photosynthetic capacity with the distribution of a limited biological resource. This perspective is useful when comparing how plants, algae, or cyanobacteria organize resources for photosynthetic function.
Rubisco abundance should be considered in relation to the conditions under which cells grow or function. Light availability, carbon dioxide conditions, and environmental stress can influence the abundance measured in plant, algal, or cyanobacterial cells. Comparing these conditions helps researchers determine whether changes in enzyme amount accompany altered photosynthetic capacity or broader environmental responses.
The measurement provides information about potential photosynthetic capacity and the allocation of nitrogen to a major carbon-fixation component. Researchers can use it to compare organisms or conditions and to examine how enzyme investment changes with light, carbon dioxide, or environmental stress. These comparisons support broader studies of photosynthetic performance rather than treating enzyme amount as an isolated observation.
Rubisco abundance measurements help connect enzyme investment with photosynthetic capacity and plant productivity. In crop research, these data can identify how carbon-fixation resources respond to light, carbon dioxide, and environmental stress. Such information contributes to efforts aimed at improving photosynthetic efficiency and, ultimately, understanding factors that may influence crop performance.
