4. Add 10ml Media +10%FCS
5. Pipette up and down to distribute cells throughout media (i.e. not clumped together)
6. Add resuspended cells to sterile universal tube 
7. Spin down 1500rpm, 3 mins
8. Take off media
9. Resuspend pellet in 2ml FCS +10%DMSO
10. Distribute in 500ul aliquots (0.5 to 2 Million cells/ml)
11. Move cells to -80^oC overnight in Mr. frosty box (filled with ethenol)
12. Finally freeze cells in liquid N₂

Unthawing

1. Warm DMEM in waterbath
2. Thaw cryovial at 37^oC quickly until cells become molten.

Introductory Course in Immunology June 22 - 28, 2007

The American Association of Immunologists 2007 Introductory Course in Immunology June 22 - 28, 2007
The University of Pennsylvania, Philadelphia, Pennsylvania Don’t miss the most comprehensive introduction to immunology available!



An intensive course taught by world-renowned teachers and researchers in immunology. This 37 ½ hour, two-part course provides a comprehensive overview of the basics of immunology for students new to the discipline or seeking more information to complement general biology or science training. Upon completion students will have the tools necessary to understand and discuss current topics and methods in immunology. Part I (June 23-25) is a comprehensive introduction to the basic principles of immunology and is suitable for students with a general biology background. Part II (June 26-28) is a lecture course covering major areas of immunology and will require an understanding of basic immunology. Parts I and II may be taken independently at the discretion of the student. Financial support for underrepresented minority scientists is available through the FASEB MARC program. Registration Deadline: June 1, 2007. Course Director: Terri M. Laufer, University of Pennsylvania School of Medicine Part I: June 22-25
