Protein Labeling Reagents
Cytoskeleton, Inc. SiR700-Actin Kit
Composed of: 35 nmol SiR700-Actin and 1 µmol verapamil. SiR700-actin is based on the far-red silicon rhodamine (SiR) fluorophore analogue SiR700 and the actin binding natural product jasplakinolide. SiR700-actin allows labeling of endogenous F-actin in live cells with high specificity and low background without the need for genetic manipulation or over-expression. The key features of SiR700-actin are i) far-red absorption and emission wavelengths, ii) cell permeability, iii) fluorogenic character, and iv) compatibility with super-resolution microscopy (e.g., STED & SIM). In addition, SiR700 actin can be used for wide-field and confocal fluorescent imaging in living cells. The emission in the far-red wavelength minimizes phototoxicity and sample autofluorescence. SiR700-actin is compatible with GFP and/or m-cherry fluorescent proteins.

AdipoGen Fluorescein dioctadecanoate
Chemical. CAS 920269-51-8. Formula C56H80O7. MW 865.23. Fluorescein dioctadecanoate is a non-fluorescent hydrophobic fluorescein derivative that can pass through the cell membrane whereupon intracellular esterases hydrolyze the dioctadecanoate group producing the highly fluorescent product fluorescein. The fluorescein molecules accumulate in cells. Fluorescein dioctadecanoate is a fluorogenic substrate for C18 esterase that generates green fluorescence upon esterase cleavage. Spectral Data lambdaEx 497nM, lambdaEm 516nm. Extinction coefficient 80000 cm-1 M-1.

Biotium CD28(204.12), CF488A conjugate, 0.1mg/mL
Recognizes a glycoprotein of 44-88 kDa, which is identified as CD28. It is the critical T-cell co-stimulatory receptor which provides to the cell the important second activation signal by binding CD80 and CD86 that are expressed by antigen presenting cells. Besides its co-stimulation role, CD28 functions in preventing T-cells from anergic hyporesponsive state or from undergoing premature apoptotic cell death. CD28 is also expressed on human fetal NK cells and some NK cell lines, whereas on murine NK cells the CD28 expression is much broader.Primary antibodies are available purified, or with a selection of fluorescent CF Dyes and other labels. CF Dyes offer exceptional brightness and photostability. Note: Conjugates of blue fluorescent dyes like CF405S and CF405M are not recommended for detecting low abundance targets, because blue dyes have lower fluorescence and can give higher non-specific background than other dye colors.
