In Vivo

Identification for tumour vasculature (frozen section):
Guidelines (Following is our recommended protocol. This protocol only provides a guideline, and should be modified according to your specific needs)[1].
1. The dye is administered to murine via lateral tail vein injection at a dose of 1 mg/kg/ in 50 μL volume.
2. Animals are killed 5 min after dye administration, and tumors are immediately excised and frozen at - 20°C.
3. Frozen sections 10 μm in thickness are rewarmed to room temperature, allowed to air dry.
4. Image using a microscope with 100W mercury lamp illumination and an epifluorescence condenser (excited at 430-490 nm, emitted at 510-520 nm.
