Fred Hutchinson Cancer Research Center

The CCEH Administrative Core provides scientific and budgetary oversight for all CCEH activities. This includes, in addition to the Pilot and Feasibility Program, an Enrichment Program that supports outside speakers, high school summer internships, and short-term on-sight training opportunities for NIDDK-funded trainees from anywhere in the US. The Administrative Core also houses a self-supporting computer graphics specialist and poster printing services.
 

Protocols

CD34 Selection Procedure

This procedure is a general method to obtain and select for the CD34+ cell compartment. It uses antibody coated immunomagnetic beads to select for those cells. It is important to follow all biohazard safety precautions when performing this procedure. CD34+ selections that we conduct use current Miltenyi processing procedures.

Procedure for Cryopreservation of Cells in Bags

This procedure is used for cryopreserving large aliquots of cells in cryo storage bags. This procedure is for cell numbers greater than 1-2 billion cells. It is important to follow all biohazard safety precautions when using this procedure. STERILE TECHNIQUE SHALL BE FOLLOWED AT ALL TIMES USING THIS PROCEDURE

Procedure for Obtaining Samples From Tubes and Bags

The purpose of this procedure is to obtain a small aliquot from either a tube of blood or larger bag of cells. The small aliquot is to be a representative sample of the main body of cells contained in the tube or bag. This aliquot can then be used for cell counts or flow cytometry staining. The information garnered from the aliquot can then be extrapolated to the larger source. For this procedure use biohazard precautions.
