Qualitative and quantitative determination of prealbumin, retinol-binding protein, Gc-globulin and C4-component in aqueous humor (author's transl)

Abstract

By using the combined disc-immunomethod, prealbumin, retinol-binding protein Gc-globulin, and C4-component were identified in human aqueous humor. These proteins can be quantitatively analyzed by single radial immuno-diffusion. The quantiative determination of retinol-binding protein and C4-component in aqueous humor could be of diagnostic value because retinol-binding protein is capable of transporting retinol (vitamin A), and C4-component is implicated in immunologic reactions. Moreover, it is noteworthy that by these immunologic methods it is possible to determine protein concentrations below 0.05 mg/100 ml.
