10 Results for "single-molecule localization" in MCE Product Catalog:
Cat. No.: HY-D1320
CAS No.: 1267539-32-1
Target:
Research Areas:
Cyanine5 azide chloride is a Fluorescent probe for cell-selective bacterial protein labeling, as well as a fluorescent dye for single-molecule imaging and dynamic tracking of intracellular organelles. Cyanine5 azide chloride can conjugate with the alkynyl side chain of propargylglycine incorporated into bacterial proteins by the engineered methionyl-tRNA synthetase variant PraRS via copper (I)-catalyzed azide-alkyne [3+2] cycloaddition reaction, thereby enabling in-gel fluorescent visualization of labeled proteins. Cyanine5 azide chloride can diffuse across cell membranes and undergo copper-free click reaction with DBCO-functionalized scAVD pre-bound to DBCO-functionalized biotin, forming fluorescent nanoprobes with enhanced brightness, photostability and localization accuracy, and exhibiting discrete photobleaching steps. The excitation wavelength of Cyanine5 azide chloride is Ex = 633 nm .

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.

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% .
Cat. No.: HY-D3437
Target:
Research Areas:
LRhod-PM is a photo-activated plasma membrane fluorescent probe based on a self-initiating photo-oxidation cascade mechanism. LRhod-PM, a non-fluorescent reduced rhodamine, is oxidized to the fluorescent form Rhod-PM upon visible light irradiation. LRhod-PM has maximum excitation and emission wavelengths of 560 nm and 585 nm, respectively. LRhod-PM enables wash-free labeling of the plasma membrane of living cells, including fine structures such as filopodia and tunneling nanotubes. LRhod-PM can be used in studies related to single-molecule localization super-resolution imaging of living cells .
Cat. No.: HY-D3438
Target:
Research Areas:
Photoswitchable PM8 is a fluorescent probe used for super-resolution imaging of the plasma membrane. Photoswitchable PM8 functions through a light-induced Z/E isomerization mechanism: in the hydrophobic cell membrane environment, the Z isomer forms a planar intramolecular charge transfer state stabilized by an intramolecular hydrogen bond, which restricts conformational freedom, reduces nonradiative decay, and produces bright fluorescence; in contrast, the E isomer lacks this hydrogen bond, has increased conformational freedom, and exhibits a fluorescence-quenched state. The fluorescence of Photoswitchable PM8 can be switched "on/off" by visible light: activation with 405 nm light forms the fluorescent Z isomer, and switching with 561 nm light converts it to the nonfluorescent E isomer. In the membrane environment, Photoswitchable PM8 enables single-molecule localization for super-resolution imaging. Due to solvent-induced quenching and aggregation, Photoswitchable PM8 has negligible fluorescence in aqueous solution, but upon binding to the hydrophobic membrane environment it produces bright fluorescence, enabling high signal-to-noise ratio imaging without washing .

Target:
Research Areas:
JF635-HTL is a Fluorescent dye for spatiotemporally controlled live cell imaging and single-molecule localization microscopy SMLM. Its detection mechanism depends on the conformational change of a photoswitchable HaloTag psHaloTag, which integrates the light-responsive AsLOV2 domain: in the dark state, the folded Jα helix of AsLOV2 maintains the dye in a predominantly closed, non-fluorescent form; upon 450 nm illumination, a metastable photo-adduct forms between a cysteine side chain and the FMN cofactor of AsLOV2, causing undocking and unfolding of the Jα helix, which propagates a conformational change to the HaloTag near the dye binding site, shifting the dye's equilibrium to the open, fluorescent form; this process is fully reversible in the dark as the Jα helix refolds spontaneously, returning the dye to the closed, non-fluorescent state. For psHaloTag1a labeled with JF635-HTL, the excitation/emission wavelengths for the ON state are Ex/Em = 642/655 nm, while for psHaloTag1b labeled with JF635-HTL, the wavelengths are Ex/Em = 639/655 nm; when bound to wild-type HaloTag, the wavelengths are Ex/Em = 640/656 nm .
