urine derived follicle-stimulating hormone(English)

• contains a higher proportion of acidic isoforms, whereas recombinant FSH [rFSH] contains a higher proportion of less-acidic isoforms. Less-acidic isoforms have a faster clearance, and thus a shorter half-life than the acidic FSH isoforms. The slow clearance of the acidic isoforms has a longer half-life and higher biological activity
