Protocol for high-throughput viability screening and gene expression of human EndoC-βH5 β cells and pancreatic islets
Bibliographic record
Abstract
Viability assays allow the assessment of toxicity induced by any treatment of interest. Here, we present a protocol to evaluate cell viability in human EndoC-βH5 β cells and human pancreatic islets using a high-throughput fluorescence viability assay. We describe the steps for cell and islet culture, reagent dilution, viability assay preparation, and performance. The protocol is compatible with RNA isolation and gene expression analysis on the same cells, and we detail procedures for reagent washout and profiling gene expression. For complete details on the use and execution of this protocol, please refer to Rampazzo Morelli et al. 1 • Protocol to measure relative cell viability of EndoC-βH5 β cells and human islets • Instructions for culturing EndoC-βH5 cells and human islets for the viability assay • Steps for reagent dilution, viability assay setup, and performance • Guidance on reagent removal for gene expression analysis from the same cells Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
