Biotium, Inc. products

Kits for succinimidyl ester labeling antibodies or other proteins with Biotium’s next-generation CF® dyes or biotin. 3 x 1 mg labeling reactions per kit.

Mix-n-Stain™ Enzyme Antibody Labeling Kits allow you to easily conjugate up to 100 ug of your antibody to a detection enzyme with minimal hands-on time and no purification. Label up to 100 ug of your antibody with HRP, alkaline phosphatase, or glucose oxidase with minimal hands-on time and no purification step.

A red fluorescent dye to covalently label dead cells, allowing cells with permeable plasma membranes to be detected in flow cytometry and microscopy.

ATP-Glo™ Bioluminometric Cell Viability Assay offers a highly sensitive assay for quantifying ATP. The homogeneous assay involves a single addition of ATP-Glo™ Detection Cocktail directly to cells in culture medium.

CF Dye Annexin V Conjugates can be used to stain the surface of apoptotic cells. The human anticoagulant Annexin V is a 35-36 kDa calcium-dependent phospholipid-binding protein with high affinity for phosphatidylserine (PS). In normal viable cells, PS is located on the inner leaflet of the cytoplasmic membrane. In apoptotic cells, however, PS is translocated from the inner to the outer leaflet of the plasma membrane, where it can be detected by fluorescently labeled Annexin V.

Similar to A-23187, 4-Bromo A-23187 is used for in situ calibrations of fluorescent Ca²⁺ indicators to equilibrate intracellular and extracellular calcium concentrations and to allow Mn²⁺ to enter cells to quench indicator fluorescence.

Unique fluorogenic membrane dyes that covalently stain the plasma membrane in live cells, and can withstand both fixation and detergent permeabilization.

Ultra sensitive and environmentally safe replacement for EtBr DNA/RNA gel stain.

D-Luciferin is a substrate for the enzyme firefly luciferase. Chemiluminescence at 560 nm is generated when luciferin is oxidized by an ATP-dependent process, catalyzed by luciferase.
