Description
The Bio-Imager Pen, which contains a nontoxic, phosphorescent writing material is designed to record data
and position information on membranes prior to exposure to X-ray film, allowing permanent records. The
pen has widespread use in molecular biology reducing waste, saving time and avoids the use of isotopic
materials. While the writing material casts a greenish white glow in the dark, it is recharged by light.
Principle: Letters or symbols written using the Bio-Imager Pen absorb light when in light conditions and release the
energy absorbed as light when in dark conditions. Film is exposed to this light and is developed as an
image. Application: Use the pen to record letters or symbols directly on the DNA ladder or on cling wrap covering the DNA
markers.
Directions to Use: To use the Bio-Imager pen, first shake the pen horizontally, and then press the tip straight down several
times until the fluid starts soaking the tip. The pen is then ready for use. Allow the writing to dry for
approximately 1-2 minutes at room temperature, and then expose to the X-ray film. Optimal images are
produced in approximately 10-12 hours.
Precaution: When not in use keep thepen tightly closed, and store in a horizontal position.
