Protein Labeling Reagents
Biotium Aminooxy-5(6)-TAMRA
Aminooxy-5(6)-ROX reacts with aldehydes or ketones to form a stable hydrazone compound under mild condition. Similar to ARP, aminooxy-5(6)-TAMRA can be used to label abasic sites in damaged DNA. Properties: Ex/Em (MeOH) = 540/565 nm; Dark red solid soluble in DMF or DMSO; Store at -20°C and protect from moisture and light; C 36 H 39 F 6 N 5 O 10; MW: 815.71
Biotium Biotin-XX MTSEA,10mg
MTSEA biotin selectively labels thiols under mild conditions. We offer MTSEA biotin with different linker lengths (Biotin-MTSEA, Biotin-X-MTSEA, and Biotin-XX-MTSEA), all of which allow selective labeling of cell surface thiols. Longer linkers should facilitate interaction between biotin and streptavidin. MTSEA biotin-XX MTSEA Biotincapcap; 2-((6-((6-((biotinoyl)amino)hexanoyl)amino)hexanoyl)amino)ethylmethanethiosulfonate Properties: White solid soluble in DMF or DMSO; Store desiccated at -20¿C; C25H45N5O6S3; MW: 607.7
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.
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 5-CARBOXYTetramethylrhodamine, SINGLE IS
Free acid form of 5-TAMRA (5-Carboxytetramethylrhodamine, single isomer). Properties: Ex/ Em (MeOH) = 540/565 nm; Dark red solid soluble in DMSO, DMF, or MeOH C 25 H 22 N 2 O 5; MW: 430.5; [91809-66-4]
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 5-(AND-6)-CARBOXY-X-Rhodamine, SUCCINIMI
5(6)-ROX, SE (full name: 5-(and-6)-Carboxy-X-rhodamine, succinimidyl ester) is an amine-reactive long wavelength rhodamine dye. Properties: Ex/Em (MeOH) = 568/595 nm; Dark red solid soluble in DMSO or DMF; Store at -20°C and protect from light; C 37 H 33 N 3 O 7; MW: 631.7; [114616-32-9].
