ABSTRACT
Double antibody sandwich-type ELISA was used to detect rhG-CSF in serum to study the pharmacokinetics of rhG-CSF, PEG-rhG-CSF and rHSA-hG-CSF in mice and to confirm that PEGlyation and albumin fusion of rhG-CSF technology can prolong half-life of G-CSF. Pharmacokinetic parameters were calculated with 3P87 software. T1/2 s of rhG-CSF, PEG-rhG-CSF and rHSA-hG-CSF are 2. 1 , 14.2 and 10. 6 h, respectively. T1/2 s of PEG- rhG-CSF and rHSA-hG-CSF are 7, 5 times than T1/2 s of rhG-CSF, respectively. Tpeak s of PEG-rhG-CSF and rHSA-hG-CSF are 15, 13 times than Tpeak of rhG-CSF, respectively. The result of ELISA indicates that PEGlyation and albumin fusion of rhG-CSF technology can prolong half-life of G-CSF.
