This protocol details the fabrication and application of a 3D-printed device for facilitating lateral tail-vein injection in mice. The tail vein–illuminating ring comprises a light-emitting diode (LED) lamp box on the side; once the tail has been illuminated by the LED, the vein is more clearly visible along the lateral side of the mouse tail.
