Hello Atoska, your protocol should explain the mixing. I use Churukian's ORO as
printed in Bancroft 5th ed. The dextrin is a stabilizer of some sort, not a
differentiator. The procedure is one step plus counterstain. For Churukian's
procedure, the working solution is a combination of the ORO-isopropanol and the
aqueous dextrin, so the literal answer to your questions is: mix the dextrin in
water, then combine before use. Filtering or letting stand may be needed
depending on which variant of the procedure you are following. In the variant I
use (p. 208 in Bancroft 5ed.) the solutions are mixed and then remain stable for
years -- until they stop working. I use this every week for muscle bxs and it
never fails and is never fickle.

Hello, please is anyone out there familiar with the Oil Red O protocol for
adipocytes which requires differentiation in 1% Dextrin? A colleague of
mine needs to know if the Dextrin has to made in H2O or Isopropanol ? The
Oil Red O is made in Isopropanol. Your prompt replies will be much
