Allgemeine Beschreibung

Monoclonal Anti-Vitamin B12 antibody reacts with vitamin B12, as well as with vitamin B12-KLH and vitamin B12-BSA conjugates in human plasma and serum.
Vitamin B12 or cobalamin is a water-soluble vitamin. It is the largest and most complex among all the vitamins. Vitamin B12 is naturally found in animal foods, meat, milk, egg, fish and shellfish.

Anwendung

Monoclonal Anti-Vitamin (B12) antibody has been used in enzyme linked immunosorbent assay (ELISA)
Monoclonal Anti-Vitamin B12 antibody produced in mouse has also been used in immunocytochemistry.

Biochem./physiol. Wirkung

Vitamin B12 serves as a cofactor for methionine synthase and L-methylmalonyl−coenzyme A mutase. It is essential for the maintenance and development of CNS. Vitamin B12 deficiency leads to megaloblastic anemia and neuropathy.
Vitamin B12 regulates genomic stability. While increased levels of vitamin B12 have been associated with hepatic and hematological disorders; cobalamin deficiency has been associated with orthostatic hypotension and depression . The antibody also detects coenzyme B12 and methyl vitamin B12, but does not associate with BSA, folic acid, and 5-methyltetrahyrofolic acid.
Vitamin B12 and folic acid can be used for treating disorders of central nervous system (CNS) development, mood, and cognitive decline, including some dementias.

Folic acid plays a critical role in the prevention of chromosome breakage and hypomethylation of DNA. This activity is compromised when Vitamin B12 (B12) concentration is low because methionine synthase activity is reduced, lowering the concentration of S-adenosyl methionine (SAM)

Elevated levels of serum cobalamin may be a sign of a serious, even life-threatening, disease. Hematologic disorders like chronic myelogeneous leukemia, promyelocytic leukemia, polycythemia vera and also the hypereosinophilic syndrome can result in elevated levels of cobalamin. Not surprisingly, a
