5-Methyltetrahydrofolic acid (5MTHFA) conjugated to KLH


Monoclonal Anti-Folic Acid antibody is suitable for use in western blot (diluted 1:1000).

General description

Folic acid (folate) is a vitamin that regulates one-carbon transfer during the conversion of homocysteine to methionine. Methionine is a precursor of S-adenosylmethionine, which is the main methyl donor for methylation reactions. Thus, folic acid is essential for regulation of DNA methylations and for epigenetic modifications that modulate gene expression. Folate deficiency has been associated with a wide range of disorders including colorectal cancers, depression, neural tube defects and cerebral dysfunctions
Monoclonal Anti-Folic Acid antibody binds to folate and detects an epitope present on both folic acid and its biologically active analog 5-methyltetrahydrofolic acid (5MTHFA). The product reacts with free folate, folate conjugated to a carrier such as KLH or BSA, and folic acid in human plasma or serum bound to the endogenous Folate Binder. The antibody does not cross-react with tetrahydrofolic acid, folinic acid, dihydrofolic acid or vitamin (B12).

Frequently Asked Questions

How does the storage temperature relate to shipping conditions?
The storage conditions that a Sigma-Aldrich catalog and label recommend for products are deliberately conservative. For many products, long-term storage at low temperatures will increase the time during which they are expected to remain in specification and therefore are labeled accordingly. Where short-term storage, shipping time frame, or exposure to conditions other than those recommended for long-term storage will not affect product quality, Sigma-Aldrich will ship at ambient temperature. The products sensitive to short-term exposure to conditions other than their recommended long-term storage are shipped on wet or dry ice. Ambient temperature shipping helps to control shipping costs for our customers. At any time, our customers can request wet- or dry-ice shipment, but the special handling is at customer expense if our product history indicates that the product is stable for regular shipment. http://www.sigmaaldrich.com/etc/medialib/docs/Sigma-Aldrich/General_Information/shippingandlong-termstoragev3.Par.0001.File.tmp/shippingandlong-termstoragev3.pdf
