WebImportantly, technical replicates should never be confused with biological replicates. In the case of qRT-PCR, the former are only informative as to the variation introduced by the pipetting or amplification process. As such, technical replicates should be averaged, and this value treated as a single data point. WebFeb 2, 2024 · Quantification was presented as mean ± SD (n = 3), and t test was used for statistical analysis (ns, not significant; *P < 0.05). (H) Decreased levels of phospho-SMAD3 after treating PC3 cells with SIS3 for 24 h. (I) No changes of AR or AR-V7 levels after treating Rv1 cells with SIS3 for 24 h.
WebSep 14, 2024 · In order to elucidate the molecular basis for the observed differences in performance, we analyzed selected cell extract samples and technical replicates of the commercial extract using state‐of‐the‐art quantitative proteomics similar to the study of Garenne et al.
