Qualitative assessment of signal:noise for the predominant tissue labeled by each mAb. “-“ indicates negligible or non-uniform labeling, poor morphology, and/or high background. “+“ indicates moderate specificity, uniform labeling, and/or robust labeling accompanied by moderate background. “++” indicates robust signal with minimal noise.
