Tectin (secretion)

Tectin is an organic substance secreted by certain ciliates.[1][2][3][4] Tectin may form an adhesive stalk, disc or other sticky secretion. Tectin may also form a gelatinous envelope or membrane enclosing some ciliates as a protective capsule or lorica. Tectin is also called pseudochitin. Granules or rods (called protrichocysts) in the pellicle of some ciliates are also thought to be involved in tectin secretion.
