According to the Japanese Pharmacopeia (JP; 17th edition*), analysis of high-molecular proteins in insulin human (genetical recombination) should be carried out with a column filled with hydrophilic silica gel and meets following requirement. The PROTEIN KW-802.5 confirmed the requirement was met.
System suitability requirement:
H1/H2:≥ 2.0
Where H1 is the peak height of the dimer and H2 is the height of the bottom between the peaks of the dimer and the monomer.
*The version at the time of the application acquisition.
Sample : 100 μL
4.0mg/mL of human Insulin containing dimer (in 0.01 N HCl aq.)
1. High molecular weight proteins
