| Title |
Resting T-Cell Exosomes ER-2 |
| Sample type |
RNA |
| |
|
| Source name |
Resting Exosomes culture #2
|
| Organism |
Homo sapiens |
| Characteristics |
cell type: Resting T-Cell Exosomes
origin: Exosome
state: Resting
|
| Treatment protocol |
When indicated, T lymphoblasts were activated with PMA (50ng ml-1) plus ionomycin (500ng ml-1). Exosomes were isolated from cell supernatants by several centrifugation and filtration steps . Briefly, cells were centrifuged (320g for 5 min) and the supernatant filtered through 0.22 μm membranes. Exosomes were pelleted by ultracentrifugation at 100000g for 60 min at 4ºC (Beckman Coulter Optima L-100 XP).
|
| Growth protocol |
Human peripheral blood mononuclear cells were isolated from buffy coats from healthy donors as previously described (Mittelbrunn et al., Nat Commun, 2011) and cultured in RPMI (Sigma) containing 10% fetal bovine serum (FBS; Invitrogen) depleted of bovine exosomes by overnight centrifugation at 100000g)
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNA was extracted with TRIzol reagent (Invitrogen) and the miRNeasy® mini kit (Quiagen),
|
| Label |
Cy3
|
| Label protocol |
miRNA Labeling Kit (Agilent Technologies) was used to label RNA. Basically, 100 ng of total RNA were dephosphorylated and Cyanine 3-pCp molecule was ligated to the 3´ end of each RNA molecule by using T4 RNA ligase.
|
| |
|
| Hybridization protocol |
100 ng of Cy3 labelled RNA were hybridized for 20 hours at 55ºC in a hybridization oven (G2545A, Agilent) set to 15 rpm in a final concentration of 1X GE Blocking Agent and 1X Hi-RPM Hybridization Buffer, according to manufacturer's instructions (miRNA Microarray System Protocol, Agilent Technologies).
|
| Scan protocol |
Arrays were scanned at 5mm resolution on an Agilent DNA Microarray Scanner (G2565BA, Agilent Technologies) using the default settings for mRNA Microarray.Images provided by the scanner were analyzed using Agilent´s software Feature Extraction version 10.7.3.1 and protocol GE1_107_Sep09
|
| Description |
Expression of mRNAs from Exosomes from Resting T-Cells
|
| Data processing |
Data were truncated to 1 and quantiles normalized using GeneSpring Software.Limma package from Bioconductor was used for statistical analysis
