Specificity / Sensitivity

Species Reactivity:

Mouse, Rat

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of mouse Mfsd2a protein.

Background

Mfsd2a is a sodium-dependent lysophosphatidylcholine symporter (1). It regulates lipid metabolism, growth and development, and motor function (2). It transports lysophosphatidylcholines consisting of omega-3 fatty acid docosahexaenoic acid (DHA) or other long-chain fatty acids. Mfsd2a was shown to be critical for the brain to take up DHA from plasma (3). Furthermore, Mfsd2a is required for the blood-brain barrier (BBB) formation and function (4). Lipids transported into endothelial cells in the central nervous system by Mfsd2a form a lipid environment essential to maintain BBB integrity (5).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
