Mutants (Isolated) List

National BioResource Project (C. elegans) charges shipping and handling fees for the strains due to Japanese government policy.
For academic users, the fee is 1,800 JPY per strain for normal strains and 3,000 JPY per strain for balanced or backcrossed strains. For commercial companies, the fee is 10,000 JPY and 20,000JPY, respectively.
We will send you an invoice in PDF format via email when the strain(s) you ordered are ready to ship. This usually takes 1-2 weeks. Once you have received the invoice, click on the URL provided in the file and follow the payment instructions on the website. Please note that we currently only accept credit card payments. As soon as the payment is confirmed, we will ship the worms.
If you have any questions, please contact Yoshina Laboratory by e-mail. We appreciate your understanding and cooperation in supporting this project. Please note that sending credit card information via e-mail etc. is very dangerous and we ask researchers never do that.
