Lycopersicon esculentum (Tomato) Lectin (LEL, TL), fluorescein (FITC), is a bright-green LEL-fluorophore conjugate. The tomato lectin LEL is widely used as marker of blood vessels and microglial cells in rodents and in neuroscience research. It is a valuable tool in studies of rodent tumor angiogenesis and the tracing of neovascular development in xenograft models and brain research. LEL-FITC can be applied directly to tissue sections, or it can be introduced through intravascular perfusion for fluorescence detection.

LEL is a very stable single-subunit glycoprotein containing ∼50 percent arabinose and galactose and may form multimeric aggregates in solution. It is provided at a 2 mg/mL concentration in 10 mM HEPES, 0.15 M NaCl, pH 7.5, 0.08% sodium azide, 0.1 mM Ca2+. If a precipitate forms upon long-term storage, warm to 37°C.
