Yes they are
Immunoglobulins, also known as antibodies, are proteins secreted by plasma cells that help the immune system recognize and neutralize harmful pathogens like bacteria and viruses.
Large proteins that are secreted from cells include growth factors, antibodies, and enzymes. These proteins are typically synthesized within the cell and then released into the extracellular space to carry out specific functions such as cell signaling, immune responses, and metabolic processes.

Which is the process by which newly-made proteins are secreted out of an animal cell?
Proteins
No; antibodies cannot produce themselves.
proteins
Antibodies do not have a nucleus, because they are not cells. Antibodies are globulin proteins.
Antibodies attack proteins. If the organism starts to produce antibodies against the essencial proteins in metabolism (as seen in autoimune disease) it can lead to death
Simple the answer is an Antibody!
