Bromo-Blue/X-cyanol Loading Buffer, 10X [show][hide]

Formula: [30% glycerol; 12.5 mg/mL bromophenol blue; 12.5 mg/mL xylene cyanol]
Volume: 20 mL

• 50% glycerol, 12 mL
• Bromophenol blue, 250 mg
• Xylene cyanol, 250 mg

Bring up to total volume with dH₂O.

Chromatin Prep Buffer A [show][hide]

Formula: [10 mM HEPES (pH 7.9); 10 mM KCl, 1.5 mM MgCl2; 0.34 M sucrose; 10% glycerol; 1 mM dithiothreitol; 1x protease inhibitor cocktail]
Volume: 100 mL

• 1 M HEPES pH 7.9, 1 mL
• 1 M KCl, 1 mL
• 1 M MgCl₂, 150 μL
• Sucrose, 11.6 g
• 50% Glycerol, 20 mL
• 1 M Dithiotreitol (DTT), 100 μL

Bring up to total volume with dH₂O. Store at 4°C. Add 100x protease inhibitor cocktail* (1:100) immediately before use.

LB Broth (Lennox) [show][hide]

Volume: 1 L

• Caesin tryptone, 10 g
• Yeast extract, 5 g
• NaCl, 5 g
• 1 N NaOH, 1 mL

Dissolve in 1000 mL dH₂O. Autoclave to sterilize. Cool to room temperature before adding antibiotics. Shortcut: Use 25 g Acros LB Broth, Lennox (BP9722-500) granules instead of caesin tryptone, yeast extract, and NaCl.
