The methotrexate ELISA uses a methotrexate polyclonal antibody to bind methotrexate in the sample or standard competitively to that pre-bound to the wells as a bovine serum albumin BSA conjugate. Anti-methotrexate antibody bound to methotrexate in the sample or standard are washed away while those captured by the immobilized methotrexate are detected with a secondary antibody horseradish peroxidase HRP conjugate.

The assay is developed with tetramethylbenzidine TMB substrate and the resulting absorbance is measured with a microplate reader at nm. The intensity of the yellow color is inversely proportional to the concentration of methotrexate. Methotrexate is a drug used in the treatment of cancer and autoimmune disease.

It is designed as an anti-folate to inhibit the metabolism of folic acid. Two distinct mechanisms of action have been described for methotrexate.

In cancer treatments, methotrexate competitively inhibits the dihydrofolate reductase DHFR by blocking folate binding. DHFR converts dihydrofolate to active tetrahydrofolate. In autoimmune disease and specifically in the treatment of rheumatoid arthritis, methotrexate appears to impact several pathways resulting in inhibition of T cell activation. The effects include suppression of T cell expression of intercellular adhesion molecules, inhibition of methyl transferase activity and increased CD95 sensitivity leading to apoptosis in active T cells.

Monitoring methotrexate levels is important to assure appropriate levels are maintained during therapy or treatment.
