STOGGLES Round Jade Med
Our Standard LucidLens™ is lightweight, shatter-proof, blue-light blocking, and sealed under the world’s best fog protection. Our non-prescription lens is molded to ultra-precise specifications, ensuring superior clarity and quality. Round Stoggles are a classic shape that is subtle, stylish, and softens stronger features. Just like eye protection, a round shape will never go out of style. Try Round if you have a square, heart, or triangle face.
Dojindo Molecular Technologies Inc PlasMem Bright Red dye (100 ul)
The plasma membrane consists of a lipid bilayer separating the intracellular environment from the extracellular space. Thus, the PM plays a central role in many cell behaviors such as cell migration, cell stretching, and signaling cascades. Additionally, PM dysfunction is an important biomarker because it is related to cell status and is linked to many diseases. PlasMem Bright dyes have higher retentivity on the plasma membrane. Furthermore, PlasMem Bright dyes are more water-soluble compared with other commercially available dyes and can be diluted with the culture medium. The PlasMem Bright dyes offer two different color options (green and red) and provide ready-to-use DMSO solutions. A working solution can be prepared easily via a single dilution step using growth medium or HBSS. Dojindo offers various reagents for cell membrane research.

Active Motif Chromeo P503 Fluorogenic Dye, Amine-Reactive, Bright Color Change, 1 mg
Chromeo P503 is a fluorogenic dye that labels proteins and peptides by binding to primary amine groups, providing clear detection with its distinct blue to red color change. Its quantum yield dramatically increases upon conjugation, enabling effective biomolecule labeling suitable for diverse applications like gel electrophoresis and chromatography. This dye distinguishes itself with a significant shortwave spectral shift, minimizing background effects for reproducible results.
Vector Laboratories Concanavalin A (Con A) Fluorescein 25 mg
Concanavalin A (ConA) recognizes α-linked mannose residues present as part of a "core oligosaccharide" in many serum and membrane-bound glycoproteins. At neutral and alkaline pH, Con A exists as a tetramer, but below pH 5.6, it dissociates into dimers of 52 kDa. Derivatizations can produce stable forms with dimeric structures. Con A requires calcium or manganese ions at each binding site, so avoid using buffers that bind calcium (such as phosphate) to dilute Con A since a gradual loss in activity may occur. This fluorescein-labeled Con A features a ratio of fluorophores to lectin protein that provides optimal staining (excitation 495 nm, emission 515 nm). Supplied as a solution essentially free of unconjugated fluorophores, it is preserved with sodium azide. The recommended inhibiting/eluting sugar is a mixture of 200 mM α-methylmannoside/200 mM α-methylglucoside.

Lumiprobe Sulfo-Cyanine5 tetrazine, 1 mg
Sulfo-Cyanine5 tetrazine is a fluorophore derivative bearing a tetrazine group for the TCO-ligation based labeling. This reagent possesses good aqueous solubility and stability in biological environments.
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 CellBrite™ Steady 488 Membrane Staining Kit | 100 labelings
CellBrite™ Steady Membrane Staining Kits allow fluorescence imaging of cell surface for up to several days in culture. The CellBrite™ Steady Dyes are unique fluorescent membrane probes that distribute between the cell surface and intracellular compartments, so cells retain cell surface staining over time. With the use of CellBrite™ Steady Enhancer, intracellular staining can be reduced or eliminated for imaging of cell outlines or boundaries.
