Protein Labeling Reagents
Biotium GloMelt™ Thermal Shift Protein Stability Kit
GloMelt™ dye undergoes fluorescence enhancement upon binding to hydrophobic regions of denatured proteins. Therefore the dye can be used to detect protein unfolding or measure thermal stability by performing a thermal shift assay, also called Protein Thermal Shift™, differential scanning fluorimetry, or Thermofluor assay. GloMelt™ dye has significant advantages over other environmentally sensitive dyes, such as SYPRO Orange and PROTEOSTAT TS dye. GloMelt™ dye generates a strong signal because it is optimized for detection in the SYBR Green channel of qPCR instruments, and therefore low reaction volumes and low protein concentrations can be used. GloMelt™ dye is compatible with high concentrations of protein stabilizers (such as glycerol and sorbitol), and also protein destabilizers. GloMelt™ dye performs very well in high detergent concentrations, unlike SYPRO Orange. This kit contains no ROX reference dye and has sufficient reagent for 2000 assays.
Biotium Tyramide Amplification Kit with HRP Goat Anti-Rabbit and CF568 Tyramide
Tyramide amplification, sometimes called Catalyzed Reporter Deposition (CARD), is an enzyme-mediated detection method that uses the catalytic activity of horseradish peroxidase (HRP) to generate high density labeling of a target protein or nucleic acid sequence in situ. The tyramide amplification method has been reported to increase the sensitivity by up to 100-fold compared to the conventional avidin-biotinylated complex procedure. The kit contains HRP goat anti-rabbit CF568 dye tyramide. The dye has an excitation/emission of 562/583 nm. The kit contains sufficient reagent for 50-150 slides.
Biotium MitoView™ 650
MitoView™ 650 is a far-red mitochondrial stain for live cells. Its staining is not responsive to mitochondrial membrane potential. With excitation/emission at 644/670 nm, and can be combined with visible red probes for multicolor imaging.

STEMCELL Technologies GloCell™ Fixable Viability Dye Red 710, Size: 100 Tests
GloCell™ Fixable Viability Dye Red 710 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 used prior to fixation, permeabilization, or cryopreservation. Cells with compromised plasma membranes become permeable to the GloCell™ dye, resulting in greater fluorescence compared to live cells in a cell viability assay.GloCell™ Fixable Viability Dye Red 710 is excited by the red laser (633 nm) with an excitation maximum of 647 nm, and it has a fluorescence emission maximum of 710 nm that can be detected using the 710/50 band pass filter used to detect Alexa Fluor 700.
