| Induced Pluripotent Stem Cell |
The parental cell line was recovered reprogrammed to an induced pluripotent stem cell line and expanded. The expanded line was evaluated for viability surface antigen expression and alkaline phosphatase activity. Pluripotency was assessed via embryoid body (EB) formation. Steady-state mRNA expression patterns of undifferentiated iPSC and EBs were determined via real-time PCR. Characterization data are included in the Certificate of Analysis. |

CYS112 AND ARG158; Weisgraber et al. [J. Biol. Chem. 256: 9077-9083 (1981)] and Rall et al. [Proc. Nat. Acad. Sci. 79: 4696-4700 (1982)] identified one of the 3 major apolipoprotein E isoforms, apolipoprotein E3. The variant has Cys112 and Arg158. This is the most common variant, with frequencies of 40% to 90% in various populations. |

CYS112ARG; Weisgraber et al. [J. Biol. Chem. 256: 9077-9083 (1981)], Das et al. [J. Biol. Chem. 260: 6240-6247 (1985)] and Paik et al. [Proc. Nat. Acad. Sci. 82: 3445-3449 (1985)] identified the apolipoprotein E4 isoform in which there is a Cys112-to-Arg substitution. This variant is found in 6% to 37% of individuals from different populations. |
