Methods are provided for reducing the number of aldehyde adducts and/or crosslinks from fixed biomolecules. In some cases, subject methods include contacting a sample having aldehyde fixed biomolecules (e.g., a biological sample such as a formalin fixed paraffin embedded (FFPE) tissue sample) with an adduct reversal agent in an amount and for a period of time sufficient to reduce the number of aldehyde fixation related adducts and/or crosslinks in the sample. In some cases, the adduct reversal agent is a compound that includes an aromatic ring and at least one of: an amine group and a proton-donating group. In some cases, the adduct reversal agent is a compound selected from the compounds of Table 1. Compositions and kits for practicing the subject methods are also provided.
本发明提供了减少固定生物分子中醛基加合物和/或交联物数量的方法。在某些情况下,所述方法包括将含有醛固定生物分子(例如生物样品,如福尔马林固定石蜡嵌入(FFPE)组织样品)的样品与加合物逆转剂接触,所述逆转剂的用量和时间足以减少样品中醛固定相关的加合物和/或交联物的数量。在某些情况下,所述加合物逆转剂是一种化合物,其包括芳香环和至少一个以下物质之一:胺基和质子供体基团。在某些情况下,所述加合物逆转剂是从表1中选择的化合物之一。还提供了用于实施所述方法的组合物和试剂盒。
