Immunoglobulin half-life
Witryna24 lip 2014 · We explore a strategy to substantially increase the half-life of recombinant proteins by genetic fusion to FcIII, a 13-mer IgG-Fc domain binding peptide (IgGBP) originally identified by DeLano and co-workers at Genentech [DeLano WL, et al. (2000) Science 287∶1279–1283]. IgGBP fusion increases the in vivo half-life of proteins by … Witryna25 sty 2014 · The half-life of each immunoglobulin can be used to estimate the rate of its catabolism. The serum half-life of colostral-derived immuglobulin G (IgG), M (IgM), and A (IgA) in calves was 20, 4.8, and 2.8 days, respectively (Banks, 1982).
