Lycopersicon Esculentum (Tomato) Lectin (LEL, TL), DyLight 594, 1 mg. Tomato lectin (from Lycopersicon esculentum) is an effective marker of blood vessels and microglial cells in rodents. Conjugation of the lectin with a fluorophore facilitates fast, one-step detection and visualization using intravascular perfusion methods or direct application to tissue sections. DyLight 594–labeled tomato lectin has an appropriate number of fluorochromes bound to provide the optimum staining characteristics for this lectin. This conjugate is supplied essentially free of unconjugated fluorochromes. Excitation maximum: 592 nm; Emission maximum: 617 nm; Color: Red. The recommended concentration range for use is 5–20 µg/ml.
