Characterization of LL4A
(A) Flow cytometry assays for the binding capacity of LL4A to Mel28-PLX cells at 4°C or 37°C, respectively. (B) Aptamer LL4A was incubated in human serum, and its biostability was evaluated by gel electrophoresis of the residual products at the indicated time points. (C) The in vitro toxicity of LL4A in Mel28, Mel28-PLX, and HaCaT cells was investigated by MTT assay.
