Figure 3. Western blot analysis of intracellular proteins of HEK-293T cells by means of polyclonal sheep antibodies to RNLS and horseradish peroxidase conjugate with rabbit antibodies to sheep immunoglobulins. K - proteins of the extract of HEK-293T cells transfected with the pcDNA4 myc-His vector. 1 - proteins of the extract of HEK-293T cells transfected with the pcDNA-hRen1 vector. 2 - proteins of the extract of HEK-293T cells transfected with the pcDNA-hRen1 (-sp) vector.
