Abstract: The present disclosure relates to the methods and systems for multimodal profiling. The method can include stabilizing a target, performing a tagmentation on the target using an agent, and generating a library using a reverse transcriptase enzyme. The agent can include a Tn5 transposome complex, a Tn5 transposase reagent, or a combination thereof, and the Tn5 transposome complex or the Tn5 transposase reagent can be loaded with an adapter. The reverse transcriptase enzyme can be configured to transcribe DNA from both a DNA template and an RNA template and perform a terminal transferase activity by template switching and an introduction of an adapter sequence into a cDNA and a transposed chromatin of the target.
