GRCF Customer Feedback 


The GRCF uses two different servers for online ordering services and several ordering portals for our products.  The links below will take you to the appropriate server.  Services using iLab are indicated by an asterisk (*).  Services using Genesifter are indicated by two asterrisks (**).  Items such as oligos, si/shRNA and other custom products which are ordered from company portals are now billed through iLab, even though ordering does not happen in iLab.  If you are not set up in iLab, please see the Core-in-a-box site for detailed instructions.  Genesifter accounts may be created on the login page.

External (non-Johns Hopkins) Customers:

Our online ordering system, Genesifter, is no longer available to external customers due to security risks.
