|
| Source name |
HEK293T
|
| Organism |
Homo sapiens |
| Characteristics |
cell line: HEK293T
|
| Treatment protocol |
The PAR-CLIP protocol was performed as described in Hafner et al. (Cell 2010, doi: 10.1016/j.cell.2010.03.009) with minor modification. HEK293T cells were transiently transfected with plasmid constructs and grown for 24 hours before adding 100 uM 4-SU and grown for another 12 hrs.
|
| Growth protocol |
HEK293T cells were maintained in a tissue culture incubator at 5% CO2, 370C in high glucose Dulbecco’s modified Eagle medium (DMEM) without pyruvate (Invitrogen) supplemented with 10% fetal bovine calf serum, 2 mM L-glutamine and 100U/ml Penicillin-Streptomycin.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
UV-irradiated cells were lysed, treated with RNAseT1, and the RNA-protein complex was immunoprecipitated with anti-FLAG agarose beads for 1 hour at 40C. RNA was labeled with gamma ATP and the crosslinked RNA-proteins were resolved in a SDS-PAGE gel. ORF1 and HuR RNA-protein complexes were cut from the gel.
Recovered RNA was converted into cDNA libraries using a small RNA cloning protocol described in Hafner et al (Methods, 2008, doi: 10.1016/j.ymeth.2007.09.009)
