* Approximate absorption (Abs) and fluorescence (Em) maxima, in nm; GFP (Green Fluorescent Protein) and RFP  (Red Fluorescent Protein) can be imaged using optical filters for fluorescein (FITC) and tetramethylrhodamine (TRITC) dyes, respectively. † These popular CellLight reagents are offered in small unit sizes (100 µL); all others are provided in a unit size of 1 mL. ‡ Also available is CellLight Nucleus-CFP (C10616) and CellLight Plasma Membrane-CFP (C10606), which generate a cyan-autofluorescent fusion protein targeted to the nucleus and plasma membrane, respectively. ** We also offer the CellLight Null (control) reagent (C10615), a negative transduction control for our CellLight targeted fluorescent reagents that comprises a suspension of baculovirus particles lacking mammalian genetic elements. 1.
