A tool-oriented guide to biotinylated IL-2 binding experiments: site-specific biotinylation principles, streptavidin capture parameters, platform setups for SPR, ELISA and flow cytometry, and troubleshooting paths for three common data anomalies.

FITC-Labeled CD7 Fc Chimera is not a natural cytokine or receptor, but an artificially designed multifunctional protein probe specifically used in immune detection technologies such as flow cytometry to identify, label, and analyze CD7-expressing cells (primarily T cells and NK cell subsets).

FITC-Labeled CD38 Fc Chimera is a recombinant protein tool that combines the extracellular domain of human CD38 with the Fc fragment of immunoglobulin G (IgG) and is labeled with fluorescein isothiocyanate (FITC). As a specific detection probe for the multifunctional immunomodulatory receptor CD38, it is non-pathogenic but serves as a core experimental reagent in key disease research areas such as multiple myeloma, autoimmune diseases, metabolic disorders, viral infections, and age-related immune decline.
