1. weigh 750 mg '''SOLID''' into a glass vial.

2, add 1 ml MeOH, dissolve

3, weigh 1.8 g '''OIL''' (add ~910 ul)

4, mix

5, add 300 ul (300mg) TREN to 1 ml MeOH, add to the above mixture

6, mix, tighten the cap

7, incubate inside an rotary oven for 2 days, temperature is 50 oC

8, add ~5 ml ddH2O to dissolve

9, add 45 ml isopropanol, mix

10, spin for 5 min at 3000 rpm

11, discard the liquid

12, add ~ 5ml ddH2O to dissolve

13, add 45 ml isopropanol, mix

14, spin for 5 min at 3000 rpm

15, discard the liquid

16, add ddH2O to 10 ml, this is called GexnExpresso ('''PHP''') Stock

17, store at -20 oC.

== '''Product''' ==

Find the best dilution, use this dilution for making transfection reagent, for example, add 2 ml stock to 50 ml, filter through a 0.22 u filter to sterize, aliquot (1 ml) and store at -20 oC.
