Overview

This is the standard 50mg/ml stock solution. This is diluted to 100μg/mL to inhibit translation (though you should check this concentration does what you think it does whenever you develop a new protocol using cycloheximide). Each person in the lab makes up their own stock of cycloheximide and keeps it in their own -20°C box.


Materials

  • Cycloheximide (MP Biomedicals, Cat #100183)
  • DMSO (Fluka 41639, Ultra for molecular biology; stored in the Flammables cabinet)

Procedure

Weigh out the appropriate amount of cycloheximide and add it to the appropriate amount of DMSO to get a 50mg/ml solution. Use the Botstein lab's balance as it is much more accurate than ours. It seems to make the most sense to aim for about 100mg (but if it is slightly over or under that is fine) and then put this in a 2ml eppendorf or similar tube (you can use a 15ml conical if you are going to make a larger volume) and add the appropriate amount of DMSO to this based on what you weighed out. Cycloheximide is bad for you (see below) so be careful with it!

*Megan N McClean: Cycloheximide is BAD for you. Check out the MSDS here: http://www.mpbio.com/product_info.php?family_key=02100183 or in the lab binder. Wear appropriate protective equipment (gloves, lab coat, glasses) when weiging it out and please make sure the balance area is clean.
