Abstract
Immunohistochemistry (IHC) is a useful technique for the localization and semiquantification of protein expression within tissues. Adult human intervertebral disc (IVD) tissues contain a large amount of auto-fluorescence which often makes immunofluorescence techniques inappropriate on tissue samples but can be applied to isolated cell samples. Thus, IHC remains one of, if not the most common application for protein detection within IVD tissue. Immunostaining localizes antigen expression through specific epitope-antibody interactions. Within the field of IVD research, IHC is commonly used on fresh frozen and paraffin embedded tissues to elucidate the expression of antigens. Here, we discuss the principles of IHC applied to formalin fixed paraffin embedded IVD tissue and supply optimized protocols for antibodies used within our group to guide research within the IVD field.

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 it
