| 摘要 |
<p>The present subject matter is directed to compositions and methods for inhibiting or preventing contamination of a cytological sample for analysis, wherein the sample is associated with a substrate. The methods disclosed herein are directed to contacting a polyanionic polymer material with a sample that is affixed to a substrate, which has a net cationic charge density. Upon contacting the sample with the polyanionic solution, contamination of the sample by other biological material, particularly cells, is inhibited or prevented.</p> |
