1
Cat. No.: HY-W800703
CAS No.: 1872449-19-8
Target:
Research Areas:
Alexa Fluor 594 azide is an azide-modified fluorescent dye and also a FRET acceptor reactant. Owing to its negligible direct absorption under 488 nm excitation light, excellent photostability, and the ability of its azide group to participate in the CuAAC reaction, Alexa Fluor 594 azide can be paired with a donor dye for single-molecule imaging via TIRFM, thereby enabling the visual monitoring of CuNP-catalyzed click reactions .
Cat. No.: HY-D1991
CAS No.: 906664-68-4
Cat. No.: HY-D0916
CAS No.: 143413-85-8
Synonyms: YOYO 1; YOYO1
Cat. No.: HY-D1305
CAS No.: 1443553-08-9
Target:
Research Areas:
ATTO 488 carboxylic acid is a bright green fluorescent dye with high photostability, which is commonly used in protein fluorescent labeling, single-molecule fluorescence imaging and super-resolution microscopy studies. The carboxylic acid form of ATTO 488 can be covalently coupled to primary amines of proteins via activation, or prepared into a maleimide derivative for coupling with thiol groups; it emits green fluorescence after labeling. Ex/Em = 488/524 nm .

Cat. No.: HY-131025
CAS No.: 1811539-88-4
Synonyms: JF585, SE; JF585, NHS
Cat. No.: HY-D2949
CAS No.: 2836233-28-2
Cat. No.: HY-138660
CAS No.: 2376841-30-2
Synonyms: HM-JF526 NHS
Target:
Research Areas:
HM Janelia Fluor 526, SE (HM-JF526 NHS) is a derivative of hydroxymethyl JF526 (HM-JF526). SMLM (single-molecule localization microscopy) imaging in standard phosphate-buffered saline (pH 7.4) revealed that the HM-JF526 label showed spontaneous blinking behavior throughout the imaging session and did not require short-wavelength activation light . Janelia Fluor fluorescent dyes can be chemically conjugated to the specific HaloTag substrate (a chloroalkane ligand) to form a fluorescent ligand, rather than binding directly to the HaloTag protein itself. Janelia Fluor products are licensed under U.S. Pat. Nos. 9,933,417, 10,018,624 and 10,161,932 and other patents from Howard Hughes Medical Institute.
Cat. No.: HY-D0922
CAS No.: 1284240-77-2
Target:
Research Areas:
Cy3.5 is a cyanine-based red fluorescent dye (Ex/Em ≈ 560-581/600-612 nm). After covalent conjugation with proteins, Cy3.5 exhibits extraordinary fluorescence enhancement with minimal quenching even at high labeling ratios. Cy3.5 can form a FRET dye pair with Cy5.5, which maintains stable FRET efficiency in various biochemical buffers and deoxygenated systems. Cy3.5 is applicable to studies related to fluorescent labeling of antibodies/proteins, single-molecule FRET imaging of double-stranded DNA and nucleosomes, SPION functionalization, in vivo tracing, and other relevant research .

Cat. No.: HY-D2984
CAS No.: 1308789-62-9
Synonyms: SNAP-PEG-NH2
Target:
Research Areas:
BG-PEG-NH2 (SNAP-PEG-NH2) is an amino-terminal fluorescent probe building block and a precursor for site-specific labeling of SNAP-tag fusion proteins. BG-PEG-NH2 undergoes one-step coupling with activated carboxyl esters to form customized SNAP-tag substrates, which covalently bind to SNAP tags via a thioether bond formed at the Cys145 site. After coupling with a caged carboxyfluorescein, BG-PEG-NH2 forms a probe with Ex/Em = 500/524 nm following ultraviolet uncaging. Coupling of BG-PEG-NH2 with SeTau-647-NHS enables visualization of GPCR signal transduction. BG-PEG-NH2 is suitable for coupling reactions in aqueous phases or buffers, conjugation of labels, and labeling of intracellular or cell-surface proteins .
Cat. No.: HY-D3446
CAS No.: 2358677-26-4
Cat. No.: HY-D2993
CAS No.: 1418275-35-0
Synonyms: BG-TMR
Target:
Research Areas:
SNAP-TMR (BG-TMR) is a cell-permeable fluorescent dye used for visualizing SNAP fusion proteins and performing single-molecule imaging for motor movement analysis. SNAP-TMR covalently binds to the active site of the SNAP tag domain on fusion proteins, thereby reporting the presence, localization, or movement of the protein. The excitation wavelength of SNAP-TMR is 561 nm, and the maximum labeling efficiency reaches 80% .
