2008-11-04 JC+NYMU
Attendees:
- JC
- NYMU
Conf call Summary
- Introductions
- Capabilities, existing NYMU technology & licensing

- set next meeting date/time 2008-11-18
2008-11-11 JC+SG
- Discussion of competitive methods for detection.
- ELISA
- You make a serial dilution and then get a good estimate of your antigen concentration by identifying the dilution at which you can first identify a color change.
