Sustainable Alternatives To Paper Towels
Prepare a slide-making area with 2-3 sheets of paper towels, a folded Kimwipe for slide cleaning, and a pencil for marking the slides. Place the Coplin jar with slides soaking in 100 methanol and a beaker of deionized or distilled water on one side and fixative with a Pasteur pipette on the other side (if you are right-handed, the slides and water should be on the left and the fixative should be on the right). The chromosome harvest can be placed either in the middle or on the same side as the fixative, with a Pasteur pipette alongside.
Paper towels and hot air hand dryers must be provided. The use of single service continuous cloth toweling is permitted provided it is dispensed from a cabinet that retracts all soiled toweling and bears the seal of the NSF or its equivalent. When disposable towels are used, a waste receptacle must be located at each hand washing facility or group of adjacent facilities.
The Southern-blot technique for detecting specific sequences in DNA fragments. The DNA fragments produced by restriction-enzyme cleavage are separated by size by agarose gel elec-trophoresis. The agarose gel is overlaid with a nitrocellulose or nylon filter and a thick stack of paper towels. The gel is then placed in an alkaline salt solution, which denatures the DNA.

Place mouse in dorsal recumbency on a paper towel and wipe the urogenital region with 70 ethanol. Cut the skin with dissection scissors at a point level with the top of the legs. Grasp the skin firmly on both sides of the incision and pull the skin outward toward the head and tail to expose the body wall. Cut open the body wall to expose the abdominal cavity. Identify and dissect out the two caudal epididymides and place them in Hepes-CZB plus 0.01 PVA (without BSA), or in a suitable cry-opreservation solution if sperm is to be cryopreserved.
Left hand Hold the frosted end of the slide between fingers and thumb (index and middle fingers on the polished side and thumb on the back side) and keep the polished side up as you lift the slide out of the beaker of water. Keep the long edge of the slide in contact with the paper towel and tilt the top edge of the slide forward quickly to drain off the excess water. Then tilt the top edge backwards until your thumb is rested on the paper towels (approximately 30 degrees between the back side of the slide and the paper towels). 7. Left hand Tilt the slide forward and tap gently on the paper towels to drain off the fixative.
Seal the open end of the capillary with a drop of wax, high-vacuum grease, or epoxy glue. If sealing the capillary with a bead of wax (the preferred method), the capillary should be wrapped with a moist paper towel. The open portion of the capillary should be left exposed. This precaution protects the crystal from heating owing to the application of a wax plug.
