  • Western Blot 1:500 - 1:5000
  • ELISA 1:5000 - 1:20000
  • Immunoprecipitation 1:100
Application Notes
This product has been assayed against 1.0 ug of Folate Binding Protein [Bovine Milk] in a standard sandwich ELISA using Peroxidase conjugated Affinity Purified anti-Goat IgG [H&L] and ABTS ELISA PEROXIDASE SUBSTRATE for 30 minutes at room temperature. A working dilution of 1:10,000 - 1:40,000 of the reconstitution concentration is suggested for this product. Highest levels of antigen binding and antibody reactivity were observed using NuncO brand MaxiSorp immunoplates.

Reactivity Notes

Cross-reacts with Cow. Not yet tested in other species.

Folate binding protein, has a high affinity for folic acid and for several reduced folic acid derivatives and mediates delivery of 5 methyltetrahydrofolate to the interior of cells. Membrane bound and soluble forms of a high affinity folate binding protein have been found in kidney, placenta, serum, milk, and in several cell lines. The 2 forms have similar binding characteristics for folates, are immunologically crossreactive, and, based upon limited amino acid sequence data, are nearly identical. There may be a precursor product relationship between the membrane and soluble forms, the membrane form having additional amino acid residues and greater molecular weight. The membrane form has been shown to mediate the transport of folate in cells grown in physiologic concentrations of folate. A function for the soluble form, which is found in serum, milk, and urine, has not been identified.
