Figure 5From: Inhibition of HIV derived lentiviral production by TAR RNA binding domain of TAT proteinCytotoxicity of Tat-P on 293T cells. To test for peptide toxicity, Tat-P, Con-P1, and Con-P2 peptides in concentrations ranging from 0 μM to 400 μM were added to 293T cells at 37°C for 6 hours, and the cell viabilities were monitored by MTT assay.Back to article page
