In histology, collectins can be studied using various techniques, including immunohistochemistry (IHC) and Western blotting. IHC allows for the visualization of collectins in tissue sections, providing insights into their distribution and localization. Western blotting can be used to quantify collectin levels in tissue extracts or fluids. Additionally, gene expression analysis techniques such as quantitative PCR can be employed to study the expression patterns of collectin genes in different tissues and under various conditions.
