Abstract:Objective To investigate the interaction between the filter (filter membrane) and Recombinant Human Granulocyte Macrophage Colony Stimulating Factor (rhGM-CSF) liquid.Methods The adsorptivity,extractablility and compatibility of the filter were tested to confirm that it met the Guangzhou Baiyunshan Baidi Biopharmaceutical Co.,Ltd.quality requirements..Results The active drug ingredient rhGM-CSF had no obvious adsorption before and after filtration.Each Millipak 20 filter could extract a total of 0.5 mg of non-volatile matter,and 0.3 mg organic carbon in total.The extracts were identified as polyacrylate by Fourier transform infrared spectroscopy (FTIR) and reversed phase-high performance liquid chromatography (RP-HPLC) analysis without biological toxicity.Both the membrane and filter showed no compatibility.Conclusion The filters and membranes used meet the drug quality requirements and can provide data support for further evaluation of the filtration process.
