## Body
### Overview
MasterPlex ReaderFit was a proprietary software developed by Hitachi Software Engineering for scientific applications, specifically ELISA curve fitting. It was part of the MasterPlex product line, which was discontinued on March 31, 2015. The online service associated with the software was shut down on September 13, 2017.

### Development and Discontinuation
The software was developed under a proprietary license, meaning its source code and internal workings were not publicly available. Its discontinuation was part of Hitachi's decision to phase out the MasterPlex product line. The shutdown of the online service in 2017 marked the end of user access to the software's functionality.

### Use and Impact
MasterPlex ReaderFit was primarily used in scientific research, particularly for ELISA curve fitting. ELISA (Enzyme-Linked Immunosorbent Assay) is a common technique in biochemistry and molecular biology for detecting and measuring antibodies or antigens. The software's specialized focus on this application made it a niche tool for researchers in the field.

### Availability and Support
The software was available in Japanese Wikipedia, indicating its relevance to a specific regional or linguistic audience. However, after its discontinuation, no further updates or support were provided, leaving users without access to the tool.

### Legacy
While MasterPlex ReaderFit is no longer in use, its development and discontinuation reflect broader trends in software lifecycle management. The shift from proprietary to open-source or cloud-based solutions may have influenced its eventual phase-out. Its legacy remains in historical scientific literature and the experiences of users who relied on it for their research.
