Bacteria Transcript Imaging Services

Transcription is a highly regulated process. In bacteria, only one type of RNA polymerase (RNAP) is responsible for the transcription of coding and non-coding RNA. Bacteria rely heavily on transcription and translation to produce proteins, which help them make specific responses to environmental changes. Therefore, visual analysis of bacterial transcription process is very important to study the interaction between protein and nucleic acid.

Bacteria Transcript Imaging Analysis

Currently, multiple analysis methods are available for transcription. In vitro single-molecule experiments can directly observe the behavior of individual molecules to determine the dynamics of their interactions. Chromatin immunoprecipitation can be used to determine the specific binding sequence of the target protein and nucleic acid through the lysate from the cell population. However, these techniques cannot analyze the spatial information of cell transcription or the dynamics involved.

CD BioSciences has been committed to the development of imaging technology for many years. We can observe the transcription mechanism of bacteria through in vivo single-molecule and super-resolution technology, revealing the binding kinetics of the proteins involved in the process.
