BMDCs raised in hypertonic microenvironment demonstrate clustering of MHCI and SIINFEKL-loaded MHCI molecules. A method alternative to the PLA assay was applied to confirm the receptor-peptide cluster formation upon exposure of BMDCs to high NaCl. (a) Immunofluorescent photomicrographs obtained using double surface staining for MHCI (H-2Db with a secondary Alexa Fluor 488-labeled antibody) and for H2-Kb-SIINFEKL complex (25D1.16 antibody directly fluorescent labeled by APEX Alexa Fluor 555 antibody labeling kit). (b) The statistical data are presented as mean ± SEM (**p ≤ 0.01, n = 16 high power fields).
