Particle Bombardment

Thu Jul 21 13:53:36 EST 1994

I am a graduate student who is carrying out transformation experiments
on Alfalfa using particle bombardment. The particles that our lab uses
are 1 micro gold pellets. Our current supplyer is Biorad who charges
over $320 Canadian for .25 g of particles. I was hoping someone may
know of a cheaper source of gold particles  than Biorad. If you do 
please let me know.

I have also read that tungstan may also be used for bombardment 
purposes; but that gold particles give higher transformation rates.
I was woundering if any of you could tell me weather gold particles
made that great a difference in your personal experience.

Thankyou for your help in this matter.
