Description générale

Monoclonal Anti-5MTH Folic Acid antibody is specific for an epitope present on 5MTHFA and does not detect folic acid. This hybridoma is a cloned cell line derived from a fusion between a mouse myeloma cell line and splenocytes from BALB/c mice immunized with 5MTH Folic acid conjugated to KLH.

Immunogène

5MTH folic acid, conjugated to KLH.

Application

Monoclonal Anti-5MTH Folic Acid antibody is suitable for use in indirect (Enzyme Linked Immuno Sorbent Assay) ELISA (1:5,000) and competitive ELISA.

Actions biochimiques/physiologiques

5-Methyltetrahydrofolate (5-MTHF) is a cofactor that regulates the conversion of homocysteine to methionine in the presence of another co-factor, vitamin B12. 5-MTHF is also involved in modulating antioxidative and cognitive functions. Increased serum 5-MTHF levels have been linked to anemia and macrocytosis. The antibody reacts with 5MTHFA as a free reagent or when conjugated to carriers such as KLH or BSA. Furthermore, the product associates with 5MTHFA bound to the endogenous folate binder in human plasma and serum. The monoclonal antibody does not cross-react with tetrahydrofolic acid, folinic acid, dihydrofolic acid, and vitamin B12.
Vitamin B12 and folic acid are metabolically interrelated. The enzyme methionine synthetase, which catalyzes the conversion of homocysteine to methionine, requires vitamin B12 and 5MTHFA as cofactors. In the absence of vitamin B12, 5MTHFA cannot be converted to tetra hydro folic acid and enter the metabolic pool of 1-carbon fragment acceptors. Vitamin B12 and folate deficiencies are the most common causes of megaloblastic anemia, abnormal hemopoiesis, interference in the maintenance of normal nerve tissue and general intracellular uptake and function disorders in humans. Folic acid deficiency is common in pregnant women, alcoholics, those whose diets do not include raw fruits and vegetables and people with structural or functional damage to the small intestine.
