Enzo Life Sciences TSQ (ultra pure), (25mg), CAS Number: 109628-27-5
Zinc dye . TSQ is an efficient membrane-permeable fluorescent probe for zinc (II). It is selective for Zn (II) in the presence of physiological concentrations of Ca (II) and Mg (II) ions. Fluorescence of TSQ is enhanced upon binding Zn (II), but the probe does not demonstrate a shift or change in emission wavelength. TSQ forms a largely insoluble 2:1 (Ligand-Metal) complex with zinc and emits blue light upon excitation at 365 nanometers. Alternative Name: N-(6-Methoxy-8-quinolyl)-p-toluenesulfonamide. Formula: C17H16N2O3S. MW: 328.4. CAS Number: 109628-27-5. Purity: ≥98% (HPLC). Solubility: Soluble in DMSO. Use/Stability: Stable for at least one year after receipt when stored as recommended. Long Term Storage: -20°C

Sigma Aldrich Fine Chemicals Biosciences Phalloidin Atto 390 suitab
Atto 390 Phalloidin is a novel fluorescent label with a coumarin structure. The dye is intended for application in the area of life science e.g. labeling of DNA RNA or proteins. Characteristic features of the label are high fluorescence quantum yield large Stokes-shift good photostability and low molecular weight.Phalloidin is a fungal toxin isolated from the poisonous mushroom Amanita phalloides. Its toxicity is attributed to the ability to bind f actin in liver and muscle cells. As a result of binding phalloidin actin filaments become strongly stabilized. Phalloidin has been found to bind only to polymeric and oligomeric forms of actin and not to monomeric actin. The dissociation constant of the actin-phalloidin complex has been determined to be on the order of 3 x 10-8. Phalloidin differs from amanitin in rapidity of action at high dose levels death of mice or rats occurs within 1 or 2 hours.

Biotium MemBrite™ Fix 488/515 Cell Surface Staining Kit, 100 Reactions
MemBrite™ Fix Cell Surface Staining Kits are designed for covalently staining the surface of live cells to conveniently visualize cell boundaries in immunofluorescence experiments. MemBrite™ Fix are new covalent cell surface stains that react irreversibly with cell surface proteins for staining that can withstand formaldehyde or alcohol fixation, and detergent permeabilization. Unlike lectins such as WGA, which bind specific targets that may vary between cell types, MemBrite™ Fix dyes react widely with cell surface proteins. MemBrite™ Fix staining is rapid and non-toxic to cells, and because MemBrite™ Fix dyes are highly water soluble, they stain cells much more evenly than traditional lipophilic membrane dyes like DiO, DiI, PKH, Vybrant, or CellMask™. This trial size kit has reagents sufficient for 100 labeling reactions. The kit contains 1 vial of MemBrite™ Fix 488/515 that is sufficient for 20 uL of 1000X dye after DMSO reconstitution.
Biotium CF640R Aminooxy
Aminooxy dyes have an aminooxy reactive group, which can be used to label a target molecule with an aldehyde or ketone group. An aminooxy group readily reacts with an aldehyde or ketone group to form a stable linkage without the use of a reducing agent. 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 CD37(IPO-24), CF568 conjugate, 0.1mg/mL
Recognizes a protein of 33-55 kDa, identified as CD37 (Workshop V; Code CD37.7). CD37 is strongly expressed on normal and neoplastic mature (sIg ) B-lymphocytes. In B-cell ontogeny, CD37 appears after the pre-B-cell stage, is maintained during peripheral B-cell development and is lost upon terminal differentiation into plasma cells.1 CD37 is also present, at low densities, on resting and activated T cells, neutrophils, monocytes, and some myelomonocytic leukemia cells. It is absent from platelets, erythrocytes. CD37 is a member of a family of tetraspan transmembrane proteins, including CD9, CD53, CD63, CD81, and CD82. It associates other tetraspan transmembrane proteins and MHC class II molecules to form a large complex at the surface of B cells and play a role in signal transduction. CD37 is a valuable and stable marker for peripheral mature B-cells and corresponding malignancies like B-cell chronic lymphocytic leukemia (B-CLL), hairy cell leukemia (HCL), and all types of B-
