A unique, individual set of antibodies, called individual specific autoantibodies (ISA) is found in blood, serum, saliva, urine, semen, perspiration, tears, and body tissues, and the antibodies are not affected by illness, medication, or food/drug intake.
A quorum is the number of members of a governing body who must be present for the body to conduct business; no binding decisions can be made unless a quorum is present. Robert's Rules of Order, the definitive source on parliamentary procedure states that a majority of members must be present to have a quorum.
Formally, the explanation is that the rules of each house require a certain number (a quorum) of members to be present in order to conduct business. If a member points out to the chair that too few members are present, the chair will call all members to the chamber, and proceedings will stop until a quorum of members arrives. This is a quorum call. In practice, nobody cares how many members are present. The chambers are almost always virtually empty, because members have better uses of their time â committee and subcommittee meetings, meetings with staffers, meetings with administration officials, meetings with constituents, meetings with lobbyists, and so on.
