Co-IP and LC-Mass - (Feb/04/2012 )

I want to use lc-mass to analyzes my co-ip .
My first question is does the buffer of co-ip can be directly used in lc-mass. I hear the buffer of co-ip cannot be used with 2D gel.
My second question this how many compositions can be analyzed using the method(co-ip add lc-mass) and how much the loading quality needed.
My third question is whether two co-ip is needed I see somebody use two different epitopes to ip the protein for example using antibody for FLAF tag and the protein own. Whether 2 co-ip need relatively more protein loading.
What is lc-mass-mass? The advantage by adding additional mass.

thanks alot!
