Serum Antibodies

Serum antibodies are specialized proteins found in blood that help the immune system identify and neutralize harmful germs like bacteria and viruses. Produced by immune cells called B cells, antibodies recognize specific parts of pathogens, called antigens, allowing the body to defend itself effectively. They also help mark invaders for destruction and can provide long-term protection after infection or vaccination. Essentially, serum antibodies are a vital component of the body's natural defense system, acting as targeted immune soldiers circulating in the bloodstream.
