From: Hepatitis B virus induces G1 phase arrest by regulating cell cycle genes in HepG2.2.15 cells
Detection of cellular growth in vitro. (A) MTT assay. HepG2.2.15 cells grew slower than HepG2 cells. (B) Colony formation assay. The average number of colonies of HepG2.2.15 cells was 17.7 ± 5.0 and that of HepG2 cells was 56.3 ± 7.6.
