AF 488 maleimide
AF 488 maleimide
0 Images
Cat. No.: HY-D2381
AF 488 maleimide is a thiol-reactive dye used to label SH groups of proteins, which can attach the AF 488 fluorophore to cysteine residue-containing proteins and peptides as well as other thiolated molecules. AF 488 maleimide enables real-time visualization of dynamic pilus extension and retraction in live bacterial cells via epifluorescence microscopy (Ex/Em = 470/520 nm) .

Cat. No.: HY-D3390
sCy5DA is a is a fluorescent D-amino acid . sCy5DA incorporates into bacterial peptidoglycan layers and cross-links via transpeptidase action, replacing peptidoglycan stem peptide D-amino acids. sCy5DA labels live bacterial cell walls, nascent peptidoglycan biosynthesis sites, and diverse bacterial species including Gram-negative, Gram-positive, and mycobacteria (Ex/Em = 646/665 nm) .

RADA
RADA

Cat. No.: HY-D1737
RADA is a fluorescent D-amino acid (FDAA) with high photostability and thermostability, which emits yellow-to-orange fluorescence. RADA shows low outer membrane permeability in wild-type Gram-negative Escherichia coli, but it targets penicillin-binding proteins and L,D-transpeptidases, mimics the interaction between acyl acceptors and enzyme intermediates, and integrates into peptidoglycan during biosynthesis. As a peptidoglycan labeling reagent, RADA metabolically integrates into the nascent peptidoglycan of live bacterial cells, labels the peptidoglycan at the poles and lateral walls of mycobacteria, and enables visualization of peptidoglycan synthesis and remodeling processes. RADA serves as a non-specific stain for fixed cells, is non-toxic to bacterial cells, and its red-shifted excitation/emission spectra reduce phototoxicity. RADA also supports virtual pulse-chase labeling experiments and stochastic optical reconstruction microscopy for sub-diffraction-limited imaging of bacterial cell walls .

SYTO-9
SYTO-9
0 Images
Cat. No.: HY-D3459
SYTO-9 is a cell-permeable fluorescent dye that can be used for nucleic acid staining. The fluorescence intensity of SYTO-9 increases significantly upon binding to RNA and DNA . SYTO-9 can stain RNA and DNA in live and dead eukaryotic cells, as well as in Gram-positive and Gram-negative bacteria. SYTO-9 is applicable for fluorescence microscopy, flow cytometry, fluorophotometry, and bacterial counting in aquatic systems (RNA: Ex/Em = 486/501 nm; DNA: Ex/Em = 485/498 nm) .
