title: [Isolation and characterization of the matrix properties of electrophoretically homogeneous immunoglobulin L-chain mRNA from mouse myeloma MORC 21].
abstract: mRNA with m. w. 4.10(5) dalton was isolated by elution of one of the fractions of poly(A)-RNA from polyacrylamide gel. During reelectrophoresis this mRNA was electrophoretically homogeneous and had the same size. The isolated fraction represented the template activity in a wheat germ cell-free system of protein synthesis and stimulated the synthesis of polypeptides, electrophoretically correspondent to L-chain of authentic immunoglobulin. Comparative data of properties of electrophoretically homogenous mRNA and analogous fraction of mRNA, isolated from sucrose concentration gradient after fractionation of total poly(A)-containing RNA are given.
