The Caki-1 cell line was established from the renal carcinoma cells of a 49-year-old male patient with clear cell carcinoma. Caki-1 cells contain many microvilli, small mitochondria,and well developed endoplasmic reticulum (ER) and golgi apparatus. This cell line is not commercially available and is only available for research purposes. Transfection of the Caki-1 cell is facilitated by Caki-1 transfection reagents ( Altogen biosystems ) to establish stable cell lines, produce consistent research and to optimize transfection of siRNA, miRNA and pDNA.
