R-PE Streptavidin is a streptavidin labeled with R-Phycoerythrin (R-PE) at a concentration of 0.5 mg/mL. R-Phycoerythrin is an orange-red fluorescent probe. Streptavidin specifically binds to biotin, forming a reversible non-covalent interaction. R-PE Streptavidin is commonly used in experiments such as immunofluorescence (IF), enzyme-linked immunosorbent assay (ELISA), immunohistochemical staining (IFH), and in situ hybridization (Ex/Em=785/813 nm).

Activated APC-AF750 is a pre-activated dual-color tandem dye for simple and efficient labeling of antibodies or other thiol-containing proteins. It can be used in experiments such as flow cytometry (Ex/Em = 565/780 nm).

HPsensor 2 is a fluorescent probe used to detect the surface hydrophobicity of proteins. The detection mechanism of HPsensor 2 relies on its amphipathic properties. The 2-methoxyethylamine substituents at positions 3 and 5 of its BODIPY core enhance water solubility, enabling it to interact with solvent-exposed hydrophobic regions on proteins. When it binds to these hydrophobic surfaces, the free rotation of the meso-aryl substituent is restricted, increasing molecular rigidity and reducing non-radiative deactivation, which results in a significant enhancement of fluorescence. HPsensor 2 exhibits weak but detectable fluorescence in aqueous environments, and its fluorescence is highly sensitive to changes in protein surface hydrophobicity (Ex/Em = 528/579 nm).
