Protein Labeling Reagents
Cayman Chemical Thromboxn B2-bIotIn 500UG
An affinity probe which allows TXB2 to be detected through an interaction with the biotin ligand
Biotium MTSEA Biotin-XX
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: 2-((6-((6-((biotinoyl)amino)hexanoyl)amino)hexanoyl)amino)ethylmethanethiosulfonate; White solid soluble in DMF or DMSO; Store desiccated at -20°C; C25H45N5O6S3; MW: 607.7.
Agilent Technologies AdvanceBio 2-AB alpha(2,3) Sialylated biantennary N-glycan library
Library consists of biantennary oligosaccharides containing alpha(2,3) linked sialic acid. The reducing termini are derivatized with the fluorescent dye, 2-aminobenzamide (2-AB).
New England Biolabs, Inc. SNAP-Cell Oregon Green – 50 nmol
SNAP-Cell Oregon Green is a photostable green fluorescent substrate that can be used to label SNAP-tag fusion proteins inside living cells or in vitro. Conjugates of Oregon Green are more photostable than those of fluorescein, and their fluorescence properties are essentially pH insensitive in the physiological pH range.
Biotium MemBrite™ Fix 405/430 Cell Surface Staining Kit, 100 Reactions
MemBrite Fix 405/430 is a blue fluorescent dye that covalently labels the surface of live cells. Unlike lipophilic membrane dyes, MemBrite is well-retained after fixation and permeabilization or methanol fixation. One vial for 100 labeling reactions (200 uL staining volume). Ex/Em 404/431 nm.
Biotium MTSEA Biotin-X
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-X: 2-((6-((biotinoyl)amino)hexanoyl)amino)ethylmethanethiosulfonate; White solid soluble in DMF or DMSO; Store desiccated at -20°C; C19H34N4O5S3; MW: 494.68.
Biotium CF640R succinimidyl ester
CF Dye Succinimidyl Esters (SE, also known as NHS esters) are amine-reactive fluorescent dyes. SE dyes are commonly used to label antibodies and other proteins on free amine groups, such as lysine residues. CF dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Far-red fluorescent CF640R dye has excitation/emission at 642/662 nm.
Biotium Fluorescein CADAVERINE
Fluorescein cadaverine can be coupled to activated carboxy groups or sulfonyl chlorides.Features: Ex/Em nm (pH 9.0) = 493/517 nm; Yellow solid soluble in DMSO, DMF, or pH>6.5 buffers; Store at 4°C and protect from lightC30H27F6N3O9S; MW: 719.61
Biotium LysoView™ 540 Dye, 50uL
LysoView™ dyes label lysosomes in live cells, and are available with blue, green, visible red, and far-red fluorescence. Far-red LysoView™ 650 is compatible with super-resolution imaging by STED and SIM.
Sigma Aldrich Fine Chemicals Biosciences Atto 647 NHS ester BioReag1MG
ATTO Atto 647 NHS ester BioReag1MG
Sigma Aldrich Fine Chemicals Biosciences Phalloidin fluorescein Iso1MG
Phalloidin is a phallotoxin produced by death cap mushroom Amanita phalloides. It is a cyclic peptide which interacts with actin and this was first identified in phalloidin-poisoned rats. It is a heptapeptide cyclic in nature with a crosslink between tryptophan at position 6 and cysteine at position 3. The side chain of amino acid 7 (I3-δ-dihydroxyleucine) in phalloidin is accessible to modifications through which fluorescently labelled phalloidin compounds can be produced.
