Figure 4From: Characterization of the ribonuclease activity on the skin surfaceSubstrate specificity of skin surface ribonucleases. Ribonuclease activity assay. 18-mer homopolymers of A, G, C or U were digested with ribonucleases of blood plasma (final dilution 400×) or ear surface (4×) from Mus musculus and with ribonucleases of blood plasma (400×) or hand surface (4×) from Homo sapiens.Back to article page
