No. Salt (NaCl) is a water soluble ionic compound. A glycoprotein is a molecular compound. They are two completely different classes of substances.
Mucin
mucin
Most glands do not have ducts. The ones that do are called exocrine glands; mainly these just are sweat glands, oils glands, digestive glands, and sexaul reproducitive glands.
Insulin is synthesized in significant quantities only in beta cells in the pancreas.
Directly into the Blood Stream. Endocrine Glands release there secretions (hormones) directly into the blood stream. That is why they are unlike Exocrine Glands.

Mucin
Sodium bicarbonate is secreted by the pancreas. The pancreas has both endocrine and exocrine function. Its secretion of sodium bicarbonate is part of its exocrine function.

The mammary gland is an exocrine gland. It has ducts through which milk is secreted.
erythropoietin

This depends whether the hormone is an EXOcrine hormone or an ENDOcrine hormone. EXOcrine hormones are secreted into a hollow cavity or the exterior to have a direct effect. I.e gastric hormones being secreted directly into the stomach to digest food. ENDOcrine hormone are secreted directly into the bloodstream to be carried to their target receptors and cells
There are two immunoglobulins in exocrine secretions: lgA & lgE
Erythropoietin is secreted in response to hypoxia. It produces a negative feedback loop that raises the oxygen concentration of the blood. Also called EPO, erythropoietin, is a glycoprotein hormone that controls red blood cell production.
The pancreas makes insulin and glucagon and excretes these into the bloodstream. These are hormones that help with regulation of sugar in the body. This is the endocrine part of the pancreatic function. It also makes enzymes that aid in digestion. It also makes bicarbonate to neutralize acids in the stomach. This is the exocrine part of the pancreatic function.
