STEMCELL Technologies GloCell™ Fixable Viability Dye Violet 540, Size: 500 Tests
GloCell™ Fixable Viability Dye Violet 540 is a fluorescent cell viability dye for staining live/dead mammalian cells in applications such as flow cytometry. The dye irreversibly binds intracellular and cell surface amine groups and can be utilized prior to fixation, permeabilization, or cryopreservation. Cells with compromised plasma membranes become permeable to the GloCell™ dye, resulting in a greater fluorescence compared to live cells in a cell viability assay.GloCell™ Fixable Viability Dye Violet 540 is excited by the violet laser at 405 nm and it has a fluorescence emission maximum of 540 nm that can be detected using the 525/50 band pass filter used to detect AmCyan.

Medchemexpress LLC Sulfo-NHS-LC-biotin sodium | 191671-46-2 | MFCD00078534 | 98.0% | 556.59 | C20H29N4NaO9S2 | 10 MG
Sulfo-NHS-LC-Biotin sodium is a water-soluble, amine-reactive sulfo-NHS ester of biotin with a long-chain spacer (LC) that enables efficient labeling of primary amines on proteins and other biomolecules. It is formulated as the sodium salt to improve aqueous solubility and is suited for selective cell-surface biotinylation, detection, and affinity capture applications.
- Amine-reactive sulfo-NHS ester for efficient biotinylation.
- Long-chain spacer reduces steric hindrance and preserves biomolecule function.
- Water-soluble sodium salt suitable for aqueous labeling of surface proteins.
- Limited membrane permeability for selective cell-surface labeling.
- High purity and well-characterized for reproducible results.
- Soluble in DMSO (approx. 175 mg/mL); store sealed and away from moisture.
