Instant Freeze-dried OP50

Simple. Convenient. Reliable.


We listened to your feedback and developed a new and improved formulation to meet your needs!  Not only is it the same consistent and convenient food for your worms but we also made it:


  • Easier to use! We got rid of the small tube and optimized the material for resuspension is in a 50 mL tube
  • Cleaner! We included a simple-to-use filtration step to reduce particulates


Use Freeze-dried OP50 from LabTIE to obtain reproducible food quality and lawn thickness. Freeze-dried  OP50 is in ready-to-use format to trigger steady feeding behavior over time and eliminate the need for time-consuming, self-breeding OP50.


The OP50 from LabTIE is a high quality cultured Escherichia coli and is used as food source for the nematode Caenorhabditis elegans.  It is used to seed NGM agar plates or add to liquid cultures (S-medium).   The Freeze-dried OP50 was cultured optimally to achieve 4 gram of pure OP50 cells which equals 1 gram of OP50 after freeze-drying. 


Resuspend the 1 gram of Freeze-dried OP50 powder in the 50mL tubes with sterile water or S-medium and you have instant and high quality OP50 food for your nematodes.

The viability of the OP50 cells is reduced due to the freeze-drying process, however there are enough cells alive to form a clear and normal OP50 lawn on your NGM plates.
