An Enzyme Immunoassay for Neopterin and Biopterin Using a Microtitre Plate Linked with N2-(3-Aminopropyl) Derivatives of Pteridines

Pteridines, 1990
A novel and sensitive enzyme immunoassay for neopterin and biopterin using a microtitre plate has been developed. The antiserum against neopterin or biopterin was incubated with samples prepared from human urine or rat tissues, and was placed in a well ...
