Best carmine quality control tissue is?

Explanation:
Quality control tissue for carmine staining should provide clear, consistent staining that lets you quickly judge if the stain is working properly across slides and runs. Liver is the best choice because hepatocytes stain reliably with carmine, giving strong, uniform cytoplasmic detail and recognizable architecture in routine sections. This stability makes it easy to spot under- or over-staining and to compare slides from different batches. Other tissues can be more variable: brain, with its delicate, lipid-rich areas, and spleen or heart, with their specialized or dense structures, may not provide as consistent a benchmark for carmine performance. So, liver offers a dependable, representative baseline for quality control.
