Introduction

The development of new immunochemical techniques has greatly enhanced our knowledge of the soluble proteins of the lens. Rao et al,¹ using Oudin's agar diffusion test,² demonstrated that bovine lens extract contains six soluble antigenic components, while François et al,³ combining agar diffusion and electrophoretic techniques,⁴ found eight such components. Halbert and Fitzgerald,⁵ working with the Ouchterlony agar diffusion technique,^6,7 found five antigenic components in the lens of the frog and four in that of the fish.

Maisel and Langman,⁸ and Konyukhov and Lishtvan,⁹ using the agar diffusion test, were able to demonstrate the presence of 7 to 13 antigenic components in the adult chick lens. In later work, Langman and Maisel¹⁰ succeeded in isolating the three main proteins of the chick lens (-crystallin: molecular weight (MW) approx 1,000,000; β-crystallin: MW 200,000 to 300,000; and -crystallin: MW 60,000), and suggested . . .
