Fluorescent Dye
Fluorescence is a phenomenon of photoluminescence in luminescence. When an atom is irradiated by light, some electrons around the nucleus jump from their original orbitals to higher energy orbitals under the influence of light energy, i.e., from the ground state to the first or second excited single-line state, etc. Due to the instability of the first or second excited singlet state, the electron returns from the excited singlet state to the ground state accompanied by released energy, resulting in fluorescence.
Fluorescent dyes can be covalently bound or physically adsorbed in the structure of the substance. The fluorescence properties allow for the characterization, localization and quantitative analysis of the labeled object. Fluorescent dyes have shown great potential for the detection of proteins, nucleic acids, cells, and immunoassays, attributed to the advantages in non-radioactive contamination, simple experimental operation and easy observation.
Fluorescent dyes have penetrated many fields such as pharmacology, physiology, environmental science, and information science, as well as functional studies of proteins and drug screening.

Peanut Agglutinin (Biotinylated)
0 ImagesCat. No.: HY-NP0182Synonyms: PNA (Biotinylated)Peanut Agglutinin (PNA) Biotinylated is a biotinylated lectin that specifically recognizes and binds to the Galβ1-3GalNAc sequence, thereby targeting SPESP1 and TF blood group antigens. As an acrosome-specific marker, Peanut Agglutinin Biotinylated stains mouse spermatocytes and sperm acrosomes with high specificity, and this binding depends not only on SPESP1 but also recognizes other testicular acrosomal glycoproteins. Peanut Agglutinin Biotinylated accurately identifies TF antigens in Reed-Sternberg cells, histiocytosis X cells, and esophageal squamous cell carcinoma, without cross-reacting with non-specific cells. Peanut Agglutinin Biotinylated maintains staining stability in both B-5 and formalin fixatives, and serves as an important tool for the study of Hodgkin's disease, histiocytosis X, and various malignant tumors.
