Q1-4. Can agents place orders instead of researchers?

Yes, you can place orders through distributors/agents instead of researchers directly.
We accept orders from distributors/agents, but end-user’s information including the purposes of research and a completed and signed Form A are still required.
For details on ordering through distributors/agents, please see this page.

If you are a customer in the USA, Canada, Australia, New Zealand and Oceania region, please contact our official distributor first after selecting your region by the [Set region] menu at the top of JCRB web page.

1. Recovery from proliferation failure of culturing human lymphocytic cells

Proliferation failure and/or cell death are often observed after thawing especially in human lymphocytic cell lines. This is possibly because these cells require autocrine factor(s) for their survival and growth. Please try the following procedures.
  1. It is important to remove DMSO contained in the cryopreservation medium. Suspend the vial contents in 10 ml of culture medium and centrifuge it once at 1000 rpm for 3 min. Avoid excessive dilution of the first culture. Re-suspend the cells in 5 ml of culture medium and start cultivation. To achieve a high density of cells, it is helpful to tilt the flask in a CO2 incubator for several days.
  2. Increase serum concentration in culture medium to 20%. The autocrine factor(s) may be substituted with serum.
  3. RPMI1640 medium is often used for human leukemic cell lines, however, the pH of this medium can increase towards alkaline, which impedes growth. If the pH of the culture medium when in the CO2 incubator is too high, please adjust it.

2. Contact information for technical inquiries

If you have a problem culturing cells, first of all, check Q&A for troubleshooting. JCRB accepts complaints within 3 months after shipment. Please make inquiries using web contact form, and describe your culturing procedure as following:
  1. Your Order Number (F1xxxxxx, A1xxxxxx or E1xxxxxx), cell number, cell name and lot number
  2. How did you preserve the frozen vial? In liquid nitrogen, or -80°C freezer? How long did you store the cells?
  3. Did you centrifuge the cell suspension to remove DMSO?
  4. Media used: manufacturer and catalog number.
  5. Did you use heat-inactivated serum or not?
  6. Additives detail and concentration (such as serum, L-glutamine, antibiotics).
  7. Scale (size) and number of flasks / dishes at the initiation of culture.
  8. Flasks and dish: manufacturer and catalog number.
  9. Did you passage the cells?
  10. If available, send photographs of your culture to JCRB by email.

Q1-3. How should the “research purpose” be described?

Please describe your purpose of research in as much detail as possible.
For example:
Terms such as “oncology research“, “cancer research“, and “basic study” are too broad. Please describe your work in detail, for instance: “In vitro testing of compounds for antitumor drug development” or “Drug screening for the therapy of hepatocellular carcinoma“.

We understand that because of confidentiality protections in each company or laboratory that particular information cannot always be disclosed. However, because intellectual property of JCRB’s cells belongs to each depositor, and because the Cell Bank needs to comprehend how cells will be benefit a user’s research, we need more specific information than what is often given.
Following the agreement, there are some cases whereby user’s purposes are reported to the depositors of cell lines.

Your understanding and cooperation are highly appreciated.

Q1-5. What are the necessary expenses?

In addition to the cell line fee (see the ‘how to order’ page), the shipping cost and commission fees apply.
Additionally, the cell line fee differs depending on the cell types and users (i.e. profit or non- profit organizations). For more details please see Price List.
If you would like to a quotation, please inquire using the “Contact” page.

If you are a customer in the USA, Canada, Australia, New Zealand and Oceania region, a predetermined expense exists. Please refer Pricing Information after selecting your region by the ‘Set region’ menu at the top of JCRB web page.

Q1-2. What documents do I need to submit? What is “Form A” ?

All requests must be accompanied by the Request and Agreement form (Form A) to JCRB. You can download Form A after completing the online application form.
A sample of Form A can be viewed by clicking this link.

Some cell lines are subject to further regulation, and another paperwork may be required. We will forward this to you after receiving your order.
For example: if you order “luciferase-expressing cancer cells”, you will be requested to exchange an Agreement form between the user and the depositor of the cell line.

Q1-1. How do I order cell lines

The procedure is:
1. Register a user account
2. Fill in the online application form
3. Submit the Request Form (Form A) to JCRB.

!! To customers in the USA and Canada:
Our official USA provider, XenoTech, will contact you on/after ordering.
