JenKem Technology now provides PEG GPC Calibration Standard kits for linear methoxy PEGs and 4arm PEGs, with MW of 2kDa, 5kDa, 10kDa, 20kDa and 40kDa. JenKem Technology’s PEG GPC standards have narrower polydispersity and more accurate molecular weights compared to other PEG standards on the market. The molecular weights of JenKem PEG standards are determined by MALDI-TOF while the polydispersity of JenKem PEG standards is determined by GPC.
JenKem Technology’s Methoxy PEG GPC Standards kit (STDMPEG) includes 200 mg each of M-PEG-2000, M-PEG-5000, M-PEG-10K, M-PEG-20K, and M-PEG-40K. JenKem Technology’s 4ARM PEG GPC Standards kit (STD4ARMPEG) includes 200 mg each of 4ARM-PEG-2000, 4ARM-PEG-5000, 4ARM-PEG-10K, 4ARM-PEG-20K, and 4ARM-PEG-40K.
