Protective proteins - Antibodies

• These proteins have protective defense function.
• These proteins combine with foreign protein and other substances and fight against certain diseases. e.g., immunoglobulin.
• These proteins are produced in the spleen and lymphatic cells in response to foreign substances called antigen.
• The newly formed protein is called antibody which specifically combines with the antigen which triggered its synthesis thereby prevents the development of diseases.
• Fibrin present in the blood is also a protective protein
