NXR ordering FAQs

QA #1 – How does the MBL invoice?

Invoices will be generated by the MBL’s Accounts Receivable department at the end of each month, and sent by mail to the billing address you provide on the New Customer Account form. Once you receive the invoice, you can either send a check payable to the Marine Biological Laboratory or contact the MBL Accounts Receivable department to make a payment by credit card (; 508-289-7266).

QA #2 – How can I pay? Do you accept PO#s and/or credit card payments?

Once you receive your invoice from the MBL you may pay via  PO OR Credit Card payment.  If you intend to use a PO# for your NXR order, either indicate the reference number on the New Customer Account form or send the PO# once established to New customer account and MTA forms can be found above.

QA #3 – What are the MBL bank wire instructions?
Please contact the MBL Accounts Receivable department for information on wiring money to the MBL (; 508-289-7266).
QA #4 – Is an MTA required?

An MTA is required if the frogs are being used off MBL campus, if you are using the frogs here at the MBL you do not need one. MTA forms can be found on


QA #5 – Is there a health report available for the frogs?

Yes. There are two options for a health report. We can send you a copy of our quarterly qPCR health testing results. Or, for a $97 fee, we can arrange for our vet to inspect the frogs we are sending to you, and furnish you with a Veterinary Health Certificate.


QA #6 – Who is the veterinarian at the NXR?

The NXR consults with the MBL veterinarian for frog care issues (and for Veterinary Health Certificates). The current MBL vet is Amy Hancock.


QA #7 – Why do you need a Grant Reference on the New Customer Account form? 

The NXR is funded by an award from the National Institute of Health, Office of the Director, Office of Research Infrastructure Programs (ORIP) and from the Eunice Kennedy Shriver National Institute of Child Health & Human Development (NICHD). The grant number that you are using to pay for the NXR resources/services is critical information when reporting to the NIH who is benefiting from this public resource.


QA #8 – What method of shipping do you use?

For domestic orders, we use UPS and ship next day air. Your order should arrive by 12 noon the next day. For international orders we use World Courier, specialists in live animal shipping.


QA #9 – Are there certain days (or months, i.e. Xenopus tropicalis) the NXR ships orders out?

For domestic orders, we ship frogs out on Mondays, Tuesday, or Wednesday. For international orders, we ship on Monday or Tuesday. We do not ship frogs if the temperature at the MBL, or at their final destination, is below freezing or predicted to be below freezing at any point during the shipment.


QA #10 – What is the shipping materials charge?

The shipping materials charge covers the cost of the Styrofoam and plastic boxes used to ship the frogs. The shipping materials are charged at cost, and so the cost varies depending on which species, and how many frogs, you order.


QA #11 – Does the NXR accept frogs from my lab that I can no longer use/house?

If you are interested in donating a line to the NXR, please contact us at We are not always able to accept frogs as our quarantine space is limited.


QA #12 – What is included in your “Research Facility Services”?

The Research Facility Services includes lab space, frog use (within reason), common reagents and equipment including picoinjectors, micro manipulators, and a fluorescent stereoscope. If you are interested in using the Research Facility, contact us at for more details regarding what reagents are available.


QA #13 – Is there an order form for me to fill out?

No. To order frogs, once you have your MTA and MBL account set up, e-mail include your name, shipping address, phone number, MBL account number, and the details of your frog order (what line you want, what gender, and how many frogs). We will then contact you to finalize your order and arrange a convenient shipping date.
