Abstract

Aims: The present study aimed to stablish and characterize an optimized protocol conformation to obtain adequate RNA quality from rodents skeletal muscle samples for sequencing studies.

Place and Duration of Study: The in vivo experiments and analyses were performed in the Laboratory of Biochemistry and Gene Expression – LABIEX of the Superior Institute of Biomedical Science – ISCB from the State University of Ceará - UECE. Between 2017-2020.

Methodology: Were used 23 samples from male Wistar rat skeletal muscle, specifically from soleus muscle. Total RNA extraction was performed using the classic TRIzol® method and commercial kit, merging steps from both. Capillary electrophoresis in the Bioanalyzer platform was used for RNA quality evaluation.

Results: (C) Analyzes of adapted protocol RNA concentration, RIN and rate 28S/18S showed satisfactory results. 28S/18S Ribosomal bands appear well defined, without small traces, which indicates RNA with high integrity and without contamination of genomic DNA.

Conclusion: Obtained RNA quality and integrity data satisfied the exigencies for posterior RNA-seq.
