RESUMEN

Rabbits were immunized with leukotriene C4 (LTC4) coupled to thiolated keyhole limpet hemocyanin (KLH) by using 6-N-maleimidohexanoic acid as a spacer molecule. Immune serum was obtained with 7.9 nmol of LTC4-specific immunoglobulin per milliliter and a mean association constant of 2.1 X 10(9) M-1. A radioimmunoassay was developed that detected 0.1 pmol of LTC4 per 1-ml sample. LTD4 and LTE4, three isomers of LTC4, the sulfones of LTC4, LTD4, and LTE4, and one isomer of LTD4 reacted to varying degrees in the assay. A number of other structurally related compounds, such as LTB4 and 5-HETE, did not react. Conditions were established to determine LTC4 levels in human plasma without loss of LTC4 during sample preparation and without the need for extraction procedures before the measurement of LTC4.
