Serum albumin binding agents Flanders Institute for Biotechnology
The present invention relates to polypeptides comprising an immunoglobulin variable domain, specifically binding to serum albumin, in particular with high affinity to rat serum albumin. The invention further relates to serum albumin binding polypeptides for increasing the half-life of therapeutic moieties and compositions, in particular for therapeutic moieties comprising multispecific immunoglobulin variable domains. Also provided herein are methods for the production of polypeptides comprising serum albumin binding immunoglobulin variable domains of the present invention.
