Phosphor Screens: The DNA Facility has small (20 X 25 cm) and large (35 X 43 cm) phosphor imaging screens for researchers to borrow.   These screens allow the indirect measure of a radioactive signal from a gel or membrane.  Samples are exposed to a phosphor screen and the excited state of the phosphor is read by a laser.

New Policy for Screens: There have been numerous complaints about phosphor screens not being available. This problem has resulted in a new policy for checking out phosphor screens. (see policy outlined below). We have also added 10 small screens and 3 large screens.  The new policy and the addition of the new screens should help.

Outline of new policy:

1. You and your PI will have to sign the Phosphor Screen Policy to check out screens. Phosphor Screen Policy
2. Screens must be checked out from DNA Sequencing Facility Staff.
3. Screens must be returned or re-checked out within 3 days.
4. Screen checkout can be extended for 3 days using the website: coreweb.icmb.utexas.edu
5. There is a $5/day late fee for screens not re-checked out or checked in.
6. If the total usage of screens total more than 60 days you will be charged a usage fee at $1/day for every day after 60 plus possible late fee charges.
7. You can look on the our sequencing website to see if screens are available. coreweb.icmb.utexas.edu
