I’ll be interested in the results of your inhibition assay from Quest. there is solid agreement between people who get negative IA result and go on to get negative western blots. There is less good agreement between people who get positive IA results and go on to do blots – some agree but we see some false positives on the IA as it compares to the blot. Let me know what you get back. Your results are definitely in the possible false positive range.
