Computational models in immunological methods: an historical review

The utilization of computational models in immunology dates from the birth of the science. From the description of antibody-antigen binding to the structural models of receptors, models are utilized to bring fundamental understandings of the processes together with laboratory measurements to uncover implications of these data. In this review, an historical view of the role of computational models in the immunology laboratory is presented, and short mathematical descriptions are given of fundamental assays. In addition, the range of current uses of models is explored -- especially as seen through papers which have appeared in the Journal of Immunological Methods from volume 1 (1971/1972) to volume 208 (1997). Each paper which introduced a new mathematical, statistical, or computer simulation model, or introduced an enhancement to an instrument through a model in those volumes is cited and the type of computational model noted.

Collection and analysis of complex ELISA data using a microcomputer

A system for automatic Enzyme-Linked Immunosorbent Assay (ELISA) data collection and processing is described. Hardware for the system consists of a Dynatech microplate reader and Apple II series microcomputer. Software developed by the authors allows automatic configuration of the reader and direct data input from the microplate reader to the microcomputer. After optical density data is input through the interface, it can be printed out as either optical density values, or as scaled values (from 0 to 9) in a color-coded matrix. Data can be stored and later recalled in either format, allowing several sets of data to be merged into one large, color-coded chart. Results from several different microplates can be combined and sorted in a single printout to expedite interpretation of data.

Computer-assisted collection and analysis of enzyme-linked immunosorbent assay data

Computer programs are presented for automating the collection, processing, and analysis of enzyme-linked immunosorbent assay (ELISA) data. The programs are written to run on an Apple Macintosh computer (equipped with at least 512 kilobytes of random access memory, a single disk drive, and an Apple Image-writer dot matrix printer) interfaced with a Bio-Rad EIA reader. The primary program is written in Pascal with associated data analysis performed by a programmable electronic spreadsheet.

Automation of protein assays with a microcomputer interfaced to a spectrophotometer

We have developed a system for semi-automatic protein quantitation assays based on an inexpensive, general-purpose microcomputer. A commercial curve fitting program was modified for direct data input from the spectrophotometer via an analog to digital converter. The software provides specific prompts for protein assays resulting in a rapid and user friendly, semi-automated system. A listing of the protein assay results are printed, or stored to a magnetic disk, along with a graphic representation of the standard curve.
