21CM-- formulas-- 4

There are now 4 different vit'n formulas made by 21CM. [+]. Alcor's publications haven't adequately keep members like me up to date on these-- or of Kent's 21CM in general. I could have been reading 21CM website on my own-- but this doesn't explain the absense of "overview" reporters who are involved in cryonics.

Supercool X-1000™
Supercool X-1000 suppresses ice formation as an additive to cryoprotective solutions intended for vitrification. It allows vitrification solutions to be safer and/or less toxic, thereby improving the performance of almost any vitrification solution.

Supercool Z-1000™
Although not a vitrification solution itself, Supercool Z-1000 is an additive that enhances the performance of vitrification solutions. Z-1000 is best used in combination with X-1000 to “clean up” residual heterogeneous ice nucleation events in vitrification solutions.

VEG Cryoprotectant
VEG Cryoprotectant is a low-toxicity formula specifically designed for the successful vitrification of living systems. VEG Cryoprotectant allows solutions--and cells in them-- to be cooled to below the glass transition temperature without the formation of ice.

VM3 Cryoprotectant
VM3 Cryoprotectant is a low-toxicity formula that is extraordinarily stable against ice formation, which makes it ideal for vitrifying both individual cells and large tissues. A mixture of pure cryoprotectants, VM3 includes Supercool X-1000, Supercool Z-1000, and Supercool PVP “ice blockers.
