Annexin - Model V CF - Dye Conjugates, Azide-Free, Lyophilized Kit
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 ...

Calcium & other Ion Indicators- Calcium Indicators & Chelators
Biotium offers a wide range of calcium indicator dyes, including Fluo-4 AM Ester, a bright and cell permeable dye that is used for high-throughput screening. The calcium indicator dyes vary in their calcium dissociation constant (Kd), color and brightness. The AM ester versions are cell permeable, and hydrolyzed by intracellular esterases to release the fluorescent dye. See our complete selection of Calcium & Other Ion Indicators, or download the Ion Indicator Brochure to learn more.

Cell & Organelle Stains- Cell Surface & Membrane Dyes
Biotium offers two new classes of dyes for covalent labeling of the cell surface that are unique in that they can withstand fixation and permeabilization for subsequent IF staining. CellBrite™ Fix dyes are fluorogenic membrane dyes that covalently stain the plasma membrane in live cells. MemBrite™ Fix dyes covalently label cell surface proteins, and are available in with a wide selection of bright and photostable colors. We also offer classic membrane and membrane potential dyes, including CellBrite™ and CellBrite™ NIR dyes, which are lipophilic carbocyanine dyes that stain the plasma membrane of cells and are non-toxic for long-term tracking.
