How to pronounce“saporin”in English

- Saporin is safe because it doesn't cross cell membranes.

then you inject the saporin conjugated to the ligand for the peptide, and only those 50 cells die.

- Ricin 'cause- - We've worked with saporin many times.

and it took about a couple of days for the saporin to actually ablate cells.

where you could take a peptide and conjugate it with a molecule called saporin.

So, you got an injection of saporin, it won't do anything because it stays outside of cells.

and then when it's inside the cell, saporin does the same thing that ricin does.
