Sample Preparation and Delivery Instructions

  • Please contact core staff for recommendations on sample collection and preparation prior to submission to the core.
  • There is a sample drop off and pickup site available in KCRB for researchers there.  See more information below.

Step 1: Sample preparation and submission guidelines

Please contact the core for guidelines on preparing samples for submission to the core.  In some cases, the core may be able to provide appropriate tubes and lysis buffers for RNA and DNA isolation projects to optimize workflows for obtaining high quality RNA and DNA samples.

Please contact core staff if you have any questions about collecting, storing, and submitting your samples for submission.

Step 2: Submit iLab request for Core Services

Submit request for GPSR services using iLab ordering system. After receiving the service ID from the Core staff, prepare samples and deliver/ship to the Core lab as described below.

Step 3: Labeling sample tubes

Samples should be submitted in a 1.5 ml RNase-free, DNase-free microfuge tube or other appropriate vessel that has been discussed with the core. Tubes should be labeled on top with the sample name. The sample name must match the name provided in the GPSR Sample Submission Form. On the side of the tube, provide the GPSR project ID (e.g. 123XY) sample name and if possible, the date of preparation.

Step 4: Packaging samples for delivery

For RNA and DNA assessment requests, please provide an aliquot of the buffer or water used for nucleic acid elution/resuspension.  This will be used for instrument blanking for UV measurements. 

In general, samples should be placed on dry ice in a styrofoam box. In some cases, DNA samples can be provided on wet ice or at 4C degrees. If working with fresh flow sorted cells or formalin fixed tissue, please contact us for special instructions.

Step 5: Sample delivery

*Please do not deliver or ship samples without first contacting GPSR staff to set-up a delivery time.*
