Senescent human fibroblasts were compared to young proliferating fibroblasts. Five different cell lines were compared. Illumina sequencing (HiSeq2000) was applied to generate 50bp single-end reads. Jena Centre for Systems Biology of Ageing - JenAge (www.jenage.de)

What this means
claude:haiku

Large-scale human bulk-RNA-seq on Illumina HiSeq 2000 platform delivering 1.87 billion reads (93.5 Gb) with exceptional quality of 97.8% Q20 and 94.1% Q30. The 0.004% N-content indicates minimal sequencing errors, and GC composition near 50% reflects standard mammalian transcriptomes, supporting robust differential expression and isoform-level studies.

How this grade was computed
Weighted mean of 4 scored metric(s) → 100/100

The A grade is a transparent weighted average. Each metric below scored from 0–100% against the published bulk-RNA-seq thresholds, weighted by its importance; nothing is hidden or subjective.
