Flow cytometric analysis of short-term fluorescence intensity and number of fluorescent HeLa S3 and SH-SY5Y cells.

Abstract

<p>HeLa S3 and SH-SY5Y cells were transiently transfected with pRc/CMV, natural CMV, SCP2 or SCP3 vector expressing <i>EGFP</i>. The cells were collected 1–4 days post-transfection (P.T.) for flow cytometric analysis. (A) Flow cytometric analysis of fluorescence intensity of all HeLa S3 fluorescent cells and SH-SY5Y fluorescent cells. (B) Flow cytometric analysis of fluorescence intensity of high intensity HeLa S3 fluorescent cells and SH-SY5Y fluorescent cells. (C) Flow cytometric analysis of the number of all HeLa S3 fluorescent cells and SH-SY5Y fluorescent cells. (D) Flow cytometric analysis of the number of high intensity HeLa S3 fluorescent cells and fluorescent SH-SY5Y cells. Data shown are representative of 5 independent experiments using HeLa S3 cells and 6 independent experiments using SH-SY5Y cells. Statistical comparisons between the promoters were done using the Kruskal—Wallis test with pairwise comparisons. Significant p-values (p ≤0.05) are indicated in the results section.</p
