We learnt to extract plasmids and transfect it into 293t cells.
We learnt to collect exosomes.
We learnt to extract RNA from exosomes and cells.
We learnt to do RT-PCR and qPCR.
siRNA screening (Failed)
14th: We extracted plasmids and cultured the 293t cells.
15th: We transfected plasmids into 293t cells.
16th: We collected cells and preserved it in Trizol.
17th: We extracted RNA, then did RT-PCR with the RNA.
18th: We did qPCR with the cDNA we got on 17th April.
21th: We reexamined the concentration of RNA, and redid qPCR.
siRNA screening (Failed)
27th: We cultured the 293t cells in a 12-well plate.
28th: We transfected 293t cells.
29th: We collected cells and extracted RNA from it.
30th: We did RT-qPCR with the RNA we extracted on 29th April.
1st: We did qPCR with the cDNA we got on 30th April.
siRNA screening (Failed), examination whether siRNA are capsulated into exosomes (Success)
8th: We extracted plasmids of 3 kinds of siRNA.
9th: We cultured 293t cells in eight D10 dishes and a 12-well plate.
