ExoBrite™ STORM CTB EV Staining Kits are validated for dSTORM imaging of EVs. This optimized formulation of Cholera Toxin B (CTB) binds to components of the EV membrane with bright signal and little to no background. Excitation/emission 583/609 nm.
The Renilla Luciferase Assay Kit 2.0 is an improved version of Biotium's Renilla Luciferase Assay Kit (catalog no. 30004) with a simplified protocol and improved working solution stability. The kit also features Biotium's water-soluble Aquaphile Coelenterazine.
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...
TrueBlack® Lipofuscin Autofluorescence Quencher, 20X in DMF 1mL - Prop65
Goat anti-mouse IgG1 isotype-specific secondary antibody labeled with CF®350 dye. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. UV-excitable blue fluorescent CF®350 dye has...
MTSPA (3-aminopropyl methanethiosulfonate hydrobromide) is a positively charged MTS reagent. White solid soluble in water, DMSO or DMF Store desiccated at -20°C C4H12BrNO2S2 MW: 250.15
A-23187, also known as Calcimycin or Calcium Ionophore III, is a calcium ionophore that rapidly equilibrates intracellular and extracellular calcium concentrations. It is commonly used for in situ calibrations of fluorescent calcium indicators. The ionophore allows Mn 2 to enter the cells and quench...
RuBPS (Ruthenium(tris(bathophenanthrolinedisulfonate), tetrasodium salt) is a negatively-charged water-soluble luminescent ruthenium complex. The complex can be efficiently excited by either UV light or visible light in the wavelength range from 400 nm to 500 nm with bright red emission centered...
The thiol-reactive quencher, CFQ520 maleimide, has a broad and intense absorption (approximately 520 nm) but no fluorescence, making it useful as an acceptor in fluorescence resonance energy transfer (FRET) applications.
This product is prepared by labeling an affinity-purified chicken anti-goat IgG (H+L) with CF®350 dye. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. UV-excitable blue...
CD16 (clone 3G8) is a mouse monoclonal antibody that recognizes the human protein CD16 (FCgRIII). CD16 is a common marker of NK cells. All antibody conjugates have been validated in flow cytometry. Each is supplied at 5 uL/test, with sufficient antibody for 25 (125uL) or 100 (500uL) tests. These...
APTS is a very useful green fluorescent dye for labeling glycoproteins or sugar molecules in general. The labeling occurs via reductive amination which involves the formation of a Schiff base between the amine of APTS and the aldehyde or ketone of the sugar, followed by the reduction of the Schiff...
This product is prepared by labeling high quality goat anti-rabbit IgG (H+L) with CF®640R dye. 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 CF®640R dye...
7-AAD (7-aminoactinomycin D) is a fluorescent DNA binding dye that is membrane impermeant and therefore generally excluded from viable cells.
This product is prepared by labeling an affinity-purified chicken anti-rabbit IgG (H+L) with CF®633 dye. 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...
Goat anti-mouse IgG1 isotype-specific secondary antibody labeled with CF®488A dye. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Green fluorescent CF®488A dye has...
Methylene Blue (MB) is a commonly used redox indicator in nucleic acid research. MB-TCO (trans-cyclooctene) is a reactive form of MB that may be used to label tetrazine tagged molecules via a copper-free reaction.
Propidium iodide (PI) is a cell impermeable nucleic acid intercalating dye. Because PI is excluded from viable cells it can be used in apoptotic studies to distinguish necrotic cells or cells in the late stages of apoptosis from viable cells or cells in early apoptosis where cell membranes are still...
This product is prepared by labeling high quality goat anti-rabbit IgG (H+L) with CF®594 dye. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes. Deep-red fluorescent CF®594 dye...
Firefly luciferase is widely used as a reporter for studying gene regulation and function, and for pharmaceutical screening. Biotium’s Steady-Luc™ HTS assay system is a homogeneous firefly luciferase reporter gene assay kit with a half-life of about 3 hours for the quantification of...
Water, Ultrapure MolecuLar Biology Grade 4L
Transferrin is a glycoprotein that binds iron for delivery to vertebrate cells through receptor-mediated endocytosis. After binding to its receptor on the cell surface, transferrin is rapidly internalized by invagination of clathrin-coated pits with formation of endocytic vesicles, the acidic...
This product is prepared by labeling high-quality goat anti-llama IgG (H+L) with CF®583R dye. CF® dyes are Biotium's line of next-generation fluorescent dyes with advantages in brightness, photostability, and conjugate specificity compared to other fluorescent dyes.
