Abstract
We described an inexpensive, portable, battery-operated photometer which can read the enzyme-linked immunosorbent assay in 96-well microtitre trays. An example is given of its use to measure IgG antibody to human collagen type II in a serum sample from a rheumatoid arthritis patient known to have a high titre of antibody to cartilage by immunofluorescence. When the same samples were read first with the portable photometer and then in a spectrophotometer (Unicam SP 1800), the accuracy of the two devices was comparable, but the readings were obtained far more quickly in the photometer.Entities:
