Iowa has one of the best biotech programs designed for school teachers that I have ever seen.  Be
sure to go to their site - much is available free to Iowa teachers.

I do have a tissue culture kit that I developed which uses a microwave instead of an autoclave, a
biocide, PPM to reduce contamination, and simple boxes as you described to keep contamination down.
 For the experiments that you want to do, I don't think you need one of my kits (the Iowa biotech
program can probably supply the chemicals) but I do recommend that you use PPM in your medium to
reduce contamination, and in some transformation experiments, it has been useful in getting rid of
the Agrobacterium.  If you would like a FREE sample of the PPM, let me know and I will have one
sent to you.

Also see the websites below for more information on plant tissue culture for the classroom and
home, and PPM.  "Talk" to you soon...........carol

| In an effort to persuade students (and faculty) that plant physiology has
| something to offer students interested in biotechnology, I am trying to add
| some experiments to the labs in my plant physiology course.  Ideally they
| would be part of a single grand experiment to last up to 12 weeks, mostly
| spent waiting for the tissue to grow.  Listed below are some of the things I
| would like to include.  If we could do them with Fast Plants, we could get a
| zillion seeds in a small space.  Does anyone have labs already invented, or
| suggestions for sources (human and text)?  
| 1. making protoplasts (I have not done this much, and never in a student lab
| setting)
| 2. transforming cells (preferably with GFP, so detection is cheap)
| 3. growing and selecting transformants
| 4. tissue culture (maybe how to grow the transformed cells--we did this long
| ago but stopped doing it as a lab)
| I recently reviewed a lab exercise in which seeds, rather than tissue
| chunks, were used for a tissue culture labs on the theory that it is easier
| to sterilize seeds and start with them, rather than sterilizing tissue.  We
| had a lot of contamination from the open air when we did tissue culture
| before, so I am planning to put together some boxes to keep the air flow
| down.   If there are plans out there (cheap ones, please), I'd like to get them.
| Thanks.
