Dies. Lastly, the cells were washed 3 much more times with FACS washing buffer and analyzed applying a GalliosTM Cytometer machine (Beckman Coulter).Real time RT-PCR to quantify mRNA expressionTotal RNAs were extracted from human islets, differentiated and undifferentiated cells making use of the RNeasy Mini Plus kit (Qiagen). The RNA (2sirtuininhibitor g) was then reverse-transcribed applying the TaqMan Reverse Transcription Kit (Applied Biosystems) and random hexamer primer mix in accordance with the manufacturer’s guidelines. For each and every reaction, the synthesized cDNA (20ng) was subjected to PCR by mixing with five L of Energy SYBR Green master mix (2X, Applied Biosystems), and 0.5 M of each and every primer (Table two) inside a total volume of 10 l. Precise pipetting was accomplished applying the automated pipetting epMotion 5075 workstation. The threshold cycle (Ct) of every target gene was normalized using the Ct of GAPDH as an internal regular. The comparative 2-Ct approach was applied to calculate the relative expression of target gene in every single sample relative to the control. The relative gene expression values were presented as Mean EM of three independent biological experiments and three technical replicates.Digital Droplet RT-PCR (dd-RT-PCR)For each dd-RT-PCR reaction mixture, the synthesized cDNA (50ng) was subjected to PCR by mixing with 12.five L of QX200 EvaGreen ddPCR supermix (2X, Bio-Rad) and 0.four M of forward and reverse primers (insulin primers listed in Table 2) in a total volume of 25 l. Next, 20 l in the dd-RT-PCR reaction mixture was loaded in to the sample properly and 70 l of DG oil was loaded in to the oil properly of a DG8 cartridge. The cartridge was placed into the droplet generator to produce the oil-PCR reaction mixture. Then, 37.five l in the mix was loaded into every nicely of a 96-well PCR plate. The PCR was performed with an annealing temperature of 60 for 40 cycles employing a two ramp rate. The good and damaging droplets had been read on a QXPLOS 1 | DOI:ten.1371/journal.pone.0164457 October 18,5 /In Vitro Generation of Functional Beta-Like CellsTable two. Primers information.
