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.
Aplicación
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.
Acciones bioquímicas o fisiológicas
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.

Biochemical indicators of water-soluble vitamin (WSV) status were measured in a nationally representative sample of the U.S. population in NHANES 2003-2006. To examine whether demographic differentials in nutritional status were related to and confounded by certain variables, we assessed the
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)

Megalin has previously been shown to bind and mediate endocytosis of transcobalamin (TC)-B(12). However, the physiological significance of this has not been established, and other TC-B(12) binding proteins have been suggested to mediate renal uptake of this vitamin complex. The

The usual dietary sources of vitamin B(12) are animal foods, meat, milk, egg, fish, and shellfish. As the intrinsic factor-mediated intestinal absorption system is estimated to be saturated at about 1.5-2.0 microg per meal under physiologic conditions, vitamin B(12) bioavailability
