azim58 - Background Info for Immunosignature to Antigen Work


My DoD Breast Cancer Predoctoral Traineeship application has some good
background information about my project.

Here's a basic outline of the paper

o Improve human health

o Courses, mentors, Biodesign environment
o Peter Lee, Kathryn Sykes

o Introduction
- description of antigen discovery platform
- 2 reagents
@ antibody-carrying sera
@ random sequence 20 mer peptides

- SMC1fs positive control
- eventual cancer vaccine

o Background
- tumor associated antigen repressed mammary tumors in rats 9
- whole cell tumor lysate was immunogenic 10
- self tumor mixtures in clinical trials 11
- more antigens would be good
- more specific antigens needed
- tumor associated antigen examples: HER2/neu, MUC1, MAGE
- Specific Antigens: frameshifts, chromosomal rearrangements,
aberrant protein modifications
- example of tumor specific antigen from lymphoma group 13
- learn from immune system (from antibodies)
- random peptide array can distinguish diseases
- need to discover original antigen
- SMC1fs positive control
- SMC1fs found more in cancer than normal cells
- plan for SMC1fs sera
- phage display technology
@ small antibodies
@ unlimited amount of phage

- compare sera and library
- conclusion

o Methods
- Identification of breast cancer specific immunosignature
@ format of slides
@ basic procedure
@ process for determining informative peptides
@ different random arrays could be used

- Probing biological samples
@ random peptide array helps purify antibodies
@ probe biological space
# Western blot
# cDNA library


- Phage Library Approach
@ Process for making phage library

- Discovering human antigens

o Relevance

Shen also has some data to show that a cancer vaccine is effective.

Questions
Have I found a paper that shows that scFv bind the same antigen as the
original antibody? I think I've read this before, but now I don't know
where it is.
