What is an AB1 file?
The .AB1 file extension is commonly associated with DNA sequencing data and is used to store electropherogram data. Electropherograms are graphical representations of the results obtained from DNA sequencing experiments, showing the intensity of fluorescence signals corresponding to different nucleotides along the sequence.
More Information.
The .AB1 file format was introduced alongside Applied Biosystems’ DNA sequencing machines to store raw sequencing data. Its purpose was to provide a standardized format for storing and sharing DNA sequencing results, ensuring compatibility across different software tools and platforms.
Origin Of This File.
The .AB1 file format was developed by Applied Biosystems, now part of Thermo Fisher Scientific, for their DNA sequencing instruments. These instruments are widely used in molecular biology laboratories for DNA sequencing and analysis purposes.
File Structure Technical Specification.
The .AB1 file format is binary and contains various sections, including header information, trace data, and quality scores. The header section typically includes metadata such as sample name, run date, and instrument settings.
The trace data section contains the raw fluorescence intensity values for each nucleotide position in the sequence, while the quality scores represent the confidence in base calls.
