GJH, is this physical view via electron microscopy thing or a testing of enzymes or other molecule levels thing? BOTH?
How many pages would a flow chart of the interactions be?
I hope I am asking about this correctly.
Wooky, first, it's not practical to measure the effects of a "receptor site" molecule, as this is inaccessible. This is particularly true of PS and it's wide distribution in the body.
Ideally, anti-ps you would be measured by Kinetic homogeneity. This would be the plasma drug concentration (Anti-PS) against concentration at the receptor site, where Anti-PS produces its therapeutic effect.
