Dear MicroSoop,

   FYI, the material that Protect Beads are made of is a special ceramic
that is acid washed, resulting in an extremely porous surface that catches
the microorganisms and aids in recovery.  The broth is TSB with glycerol
and a hypotonic addative designed to keep ions inside the cell during the
freezing and thawing process.  This leads to increased recovery.  I'm very
happy to hear that you've had success at recovery for up to 5 years.

   Anyone requesting further info. may contact Red River Scientific at

Best  regards,  Jim Roberts
