immunofluorescence

Direct Blue 1 (Pontamine sky blue), a counterstain for background autofluorescence in immunofluorescence histochemistry, structurally resembles glutamate and operates as a potent, competitive VGLUT inhibitor, not impacting plasma membrane transporters. This compound stands out as the inaugural small molecule PrP ligand to inhibit Aβ binding.

5(6)-FITC (Fluorescein isothiocyanate), or Fluorescein 5(6)-isothiocyanate, is a versatile amine-reactive derivative of fluorescein dye. It serves as an effective label for antibodies and other probes, finding utility in fluorescence microscopy, flow cytometry, and immunofluorescence-based assays such as ELISA and Western blotting.

Hemoglobin, which is the primary cause of sickle cell disease (SCD) abnormalities, can be utilized to determine fetal hemoglobin through time-resolved immunofluorescence assay [1].

JF526-Taxol (TFA) serves as a versatile scaffold for fluorogenic probes, including ligands for self-labeling tags, stains for endogenous structures, and spontaneously blinking labels for super-resolution immunofluorescence [1].
