 +
 +
1. Grow BM3 wt, BM3 10, BM3 13, in 4ml of LB + Amp media overnight from gylcerol stock in -80 C freezer<br/>
 +
2. Take 250ul of this culture and a dd to 25ml of new LB + 25 ul Amp; grow at 37 C for approx. 2 hours.<br/>
 +
3. When OD@600nm = 0.4, add isopropyl-Dthiogalactopyranoside (IPTG) to a final concentration of 0.50 mM. For our 25mL samples we added 12.5 ul of IPTG 1M.<br/>
 +
4. Get to mid log phase OD@600nm > 0.8, this should take approx. 2 hours.<br/>
 +
5. Transfer contents to Falcon tubes.<br/>
 +
6. Pellet for 5:00min at 13.2k rpm and resuspend cells in 25ml of this media:<br/><br/>
 +
- 500ml 1% gylcerol Tris buffer with salene<br/>
 +
-Tris Buffred Saline (TBS), pH 7.4<br/> of 10 mM Tris and 150 mM NaCl.<br/>
 +
- 500 ml of TBS can be prepared by dissolving 0.605 g of Tris base and 4.35 g of NaCl in 500 ml of distilled water. Adjust the pH before use.<br/>
 +
- Add 5ml of glycerol<br/><br/>
 +
6. Autoclave in 1L container<br/>
 +
7. Add 0.75 mg resveratrol (solubility 0.03 g/L) meaning a concentration of 0.03 g/L<br/>
 +
8. Grow at 30 C for 36 h, taking 50ul samples of culture<br/>
 +
9. Dip the capillary tubes in the 50ul sample and spot on TLC plate<br/>
 +
10. Put plate in developing chamber, add ~10ml of Normal buffer to the solution. Cover with the aluminum foil. Develop to ~1cm from the top.<br/><br/>

            (5ul amp + 5ul cm)<br/>
 +
<br/>
 +
Grow cultures for 14-16hrs at 37 degrees C<br/><br/>
 +
 +
Note: <br/><br/>
 +
*amp: Ampicillin 100 <br/>
 +
*cm: Chloramphenicol 34<br/>
 +
<br/>
 +
2) Subculture each culture by adding 50ul of overnight culture into 5ml LB (with appropriate antibiotics as step one). Since there are two of each culture, label one of each duplicate “induced” and the other duplicate “un-induced”.
 +
<br/><br/>
 +
Grow cultures for 3 hrs at 37 degrees C<br/>
 +
<br/>
 +
3) Induce the cultures labeled “induced” by adding 1.5ul of the IPTG stock (stock is 1M) for a final concentration of 300 uM IPTG.
 +
<br/><br/>
 +
Grow cultures for 6 hrs at 37 degrees C<br/>
