Carborundum and transfer of high MW molecules

[kirtikara at aesop.rutgers.edu]

I'm looking for methods to transfer high MW molecules such as small peptides  into INTACT plant and fungal cells.  Someone mentioned the use of Carborundum.  Could anyone please provide me with more informations about this?  And is there other methods available?
Thanks in advance.
