My thanks to a poster from another forum.

"We will get a price exceeding $1000 for sure. Look at this site www.latoxan.com selling 92% purity polyprenols (ropren is around 96% purity I think).

L6094 POLYPRENOLS

presenting an ionophoretic activity by peroxidation of membrane lipids, leading to activation of calcium current through the membrane.

Polyisoprenoid C55H90O(~3/4), C60H98O(~1/4), C65H106 from plants of the Gossypium genus, Malvaceae.

Molecular Weight : 766 Da.(undecaprenol); 834 Da.(dodecaprenol).

Solubility in : well in ethanol, chloroform, hexane and acetone.

Purity min. : 92 %.

Biological Activity : 5 x 10-5 M multiply by 9 the lipids peroxydation. The ionophoretic activity of Polyprenols is due to this peroxidation of membane lipids and the channels induced in lipid bilayers present a low conductance and a selectivity Ca2+/K+ of 2.5/1.

Toxicity (LD50) : not toxic.

Storage recommendations : Stable in dry state during 6-12 months; store at +4°C, in dark place.

CAS Reg. No. : 308068-00-0
