Protein Labeling Reagents
Lumiprobe CYANINE3 NHS ESTER 5MG
Amino-reactive yellow emitting fluorescent dye for the labeling of proteins/peptides and amino-oligonucleotides. For the labeling of sensitive proteins, use water-soluble sulfo-Cyanine3 NHS ester.
Biotium Sulforhodamine 101-PEO3-amine (Texas Red-PEO3-amine)
Sulforhodamine 101-PEO 3 -amine has a long water-soluble spacer separating the dye and the amine group. The dye can be coupled to activated carboxy groups or sulfonyl chlorides.Properties: Ex/Em (MeOH) = 583/603 nm; Dark purple solid soluble in DMSO or DMF; Store at 4°C and protect from light; C 39 H 48 N 4 O 9 S 2; MW: 780.95
Biotium Eosin-5-isothiocyanate
Eosin-5-isothiocyanate is a good photosensitizer and can be used to selectively label amines. It has a quantum yield of 0.57 for singlet oxygen generation, which makes it useful for photoconversion of electron-rich materials such as diaminobenzidine (DAB) or fluorescent dyes into highly electron-dense materials for high resolution electron microscopy studies. Additionally, eosin is a good fluorescence acceptor for fluorescein (FAM), dansyl and coumarin dyes in fluorescence resonance energy transfer (FRET). Properties: Ex/Em (pH 9) = 521/544 nm; e = 95,000; Orange red solid soluble in DMF or DMSO; Store at -20°C and protect from light; C 21 H 7 Br 4 NO 5 S; MW: 704.96
Aat Bioquest 6-HEX, SE [6-Carboxy-2',4,4',5',7,7'-hexachlorofluorescein, succinimidyl ester] *Single Isomer*
6-HEX, SE is the amine-reactive succinimidyl ester of 6-HEX acid. It is widely used in nucleic acid sequencing and related research.
Biotium Mix-n-Stain™ Biotin Antibody Labeling Kit, 1x(50-100ug) labeling
Mix-n-Stain™ biotin antibody labeling kits are a revolutionary antibody labeling technology that allows you to label your antibody with biotin in 30 minutes without a purification step. The labeling procedure tolerates many common buffer components and antibody stabilizers. Choose from kit sizes to label 5-20 ug, 20-50 ug, or 50-100 ug of your antibody.
Biotium LipidSpot™ Lipid Droplet Stains 610, 125ul
LipidSpot™ stains are fluorescent dyes that rapidly stain lipid droplets in live or fixed cells, with no wash step and minimal background.Rapidly and specifically stain lipid droplets. Minimal background, no wash required.
Biotium GloMelt™ Thermal Shift Protein Stability kit
GloMelt™ dye undergoes fluorescence enhancement upon binding to hydrophobic regions of denatured proteins. GloMelt™ can therefore be used to detect protein unfolding or protein thermal stability by performing a thermal shift assay, also called differential scanning fluorimetry or Thermofluor assay.
LICOR IRDye 680RD BoneTag™ Optical Probe (4 x 10 nmol)
IRDye 680RD BoneTag Optical Probe is a calcium-chelating compound conjugated to IRDye 680RD near-infrared dye. Using IRDye NIR dyes extends fluorescence signal detection to the near-infrared fluorescent region of the spectrum without affecting the compound’s ability to function as a marker of the mineralization process. NIR fluorescence detection improves depth of penetration due to low tissue autofluorescence, translating to low background interference. Calcium-chelating compounds have been used effectively for the detection of bone mineralization, growth, and morphological changes, including tetracycline derivatives, xylenol orange, alizarin, calcein, and fluorescein. NIR-labeled pamidronate has also been successfully used for detection of arterial calcification in non-invasive optical imaging.
Lumiprobe Cyanine5 NHS ester, 1263093-76-0, 25mg
Molecular formula: C36H42N3BF4O4, Molecular weight: 667.54, Appearance: dark blue solid, Solubility: very poorly soluble in water (0.19 mM = 127 mg/L), good in polar (DMSO, DMF) and chlorinated (DCM, chloroform) organic solvents; Amine-reactive red emitting fluorescent dye for the labeling of proteins/peptides and amino-oligonucleotides. For the labeling of sensitive proteins, use water-soluble sulfo-Cyanine5 NHS ester.
