Sample GSM6727528 Query DataSets for GSM6727528
Status Public on Sep 07, 2023
Title Mouse timecourse KPC day30 Tumor spatial transcriptomics section A1
Sample type SRA
 
Source name Tumor
Organism Mus musculus
Characteristics tissue: Tumor
strain: C57BL/6N
genotype: WT
Sex: F
time: Day 30
Extracted molecule polyA RNA
Extraction protocol Tumor biopsies of day-30 orthotopic mouse PDAC were gently washed in PBS, snap frozen via bathing in liquid nitrogen-chilled isopentane and embedded with Optimal Cutting Temperature (OCT) compound. From five to ten sections were collected to evaluate RNA quality at TapeStation system (Agilent). The tissue blocks were then processed to retrieve two non-sequential 10µm sections (100 µm apart), which were placed within the capture areas of a Visium slide equilibrated at cryostat temperature (-20°C). Sections were immediately fixed in chilled methanol at -20°C for 30 min and stained via immunofluorescence as stated above preserving RNA degradation using buffers supplemented with Recombinant RNase inhibitor (Takara 2313A, 2 U/µl). Whole-slide images were acquired using the MAVIG RS-G4 (Caliber I.D.) confocal microscope at 20x magnification. Barcoded libraries were generated by permeabilizing tissue at 37°C for 15 min and performing in situ reverse transcription at 53°C for 45 min, followed by second-strand synthesis at 65°C for 15 min. cDNA was denatured and transferred to tubes for PCR amplification and library construction, including fragmentation, adaptor ligation and sample indexing.
Spatial transcriptomics data were generated using the Visium Spatial Gene Expression Reagent Kits (10X Genomics) according to the manufacturer’s instruction.
