however , lactoferrin was major protein component in nuclei isolated from untreated cells , cells treated with other fixatives , or cells preincubated in buffered saline prior to formaldehyde-acetone fixation . formaldehyde-acetone treatment of nuclear materials containing lactoferrin did not extract lactoferrin or mask it from detection , thus indicating that lactoferrin found in the mature neutrophilic granulocyte nucleus is most likely acquired from other cellular organelles during tissue processing .
