Protective effects of anti-ricin A-chain antibodies delivered intracellularly against ricin-induced cytotoxicity

Figure 3 Neutralizing effect of MTS-conjugated dgA Ab against ricin-induced cytotoxicity. To confirm the neutralizing activity of dgA Ab conjugated to the MTS cell-penetrating peptide, RAW264.7 cells were co-incubated with ricin and MTS conjugated to dgA Ab (MTS-dgA Ab) or MTS-conjugated to control IgG (MTS-IgG) for 24 h. Cell viability was quantitated using the MTT assay.
