Human Tears: Electrophoretic Characteristics of Specific Proteins

Abstract
Tear-specific proteins have been investigated. Protein with a relative mobility higher than that of albumin in non-denaturing electrophoresis has been shown to be highly heterogeneous. It is composed of at least six proteins, some of them being probably multimeric proteins. Their isoelectric points and the apparent molecular weights of their subunits have been estimated. Another tear-specific protein was found. Its molecular weight is 31,000 daltons and it is dissociated in the presence of reducing agents.
