Improved enzyme immunosorbent assay for mouse prolactin using penicillinase as label.
Enzyme immunosorbent assay (EIA) for mouse prolactin was established by modifying a method originally developed for human prolactin by Shrivastav et al. This simple, sensitive, rapid, and reproducible assay utilizes penicillinase as the labeling enzyme, rabbit anti-mouse prolactin antibody (Ab) and goat anti-rabbit Ig Ab as the first and second antibodies. Prolactin reference preparations and enzyme-conjugated prolactin were mixed with the first Ab and incubated for 0.5 h at 4 degrees C (24-48 h for serum samples). Then, the sample mixture was transferred to the wells of microtiter plate coated with the second Ab. After being kept at room temperature for 2 h, the plate was washed and filled with substrate solution (penicillin V). Absorbance at 620 nm was measured with an ELISA reader to quantitate the amount of conjugated prolactin bound to the second Ab. The prolactin levels obtained by this assay exhibited good correlation with those measured by radioimmunoassay (RIA) (y = 0.95x + 9.14, r = 0.943), and the sensitivity of EIA was equivalent to that of RIA (1.7 ng/ml). The CVs of intra-assay and inter-assay by EIA for mouse serum samples ranged comparably to those by RIA.Y Tomita, R W Engelman, I Bauer-Sardina, N K Day, R A Good
