Tool Details

  • Tool name: Cyclin B1-Venus Reporter Cell Line [RPE1 cycB1-venus/+ KI clone 20G11]
  • Alternate names: CCNB1
  • Tool type: Cell Lines
  • Parental cell line: RPE1
  • Organism: Human
  • Tissue: Eye
  • Model: Reporter
  • Conditional: Yes
  • Description: Somatic knock-in reporter cell with endogenous expression of cyclin B1 fused to the yellow fluorescent protein Venus (cyclin B1-Venus fusion protein). Different cyclins exhibit distinct expression and degradation patterns which contribute to the temporal coordination of each mitotic event. This Cyclin B1 cell line functions as a cell cycle reporter across the G2/mitotic-specific phase of the cell cycle. See also the Mad2 and Cyclin A2 versions of these cell lines for a broader analysis of the different phases of the cell cycle. This cell line is an endogenous reporter for cyclin B1 levels and activity.
  • Research area: Cell Cycle
  • Production details: To generate the cell line recombinant adenovirus-associated virus (rAAV)-mediated gene targeting was used to fuse the open reading frame (ORF) of yellow fluorescent protein (Venus) with exon 9 of the CCNB1 (Cyclin B1) gene in hTert-RPE1 cells (RPE1; retinal pigment epithelial). RPE1 cells were chosen because they have a normal diploid karyotype, are not transformed and exhibit little cell death when arrested in mitosis; tagging the endogenous Cyclin B1 protein in RPE1 cells avoided the complications of mosaic protein levels in the cell population produced by ectopic expression.
