anticalin


anticalin

A protein derived from a lipocalin (also known as cytosolic fatty acid binding protein) which is genetically engineered to modify its binding properties. Anticalins have the advantage of a monoclonal antibody’s specificity for small lipid molecules (e.g., steroids, bilins, retinoids and lipids), better tissue penetration and thermostability, but without the large size (they are 8-fold smaller) and can also batched in E coli, eliminating the need for animal extraction..
