Antibody Drug Conjugate Mimic Enables LC-MS Method Development Without Risk
Here we show how LC and MS methods may be optimized using a non-toxic surrogate of the ADC, an “ADC-mimic”, that behaves very similarly to the Cys-linked ADC Adcetris (Seattle Genetics).
Quantification of Host Cell Proteins
Residual presence of host cell proteins (HCPs) in recombinant therapeutic products has considerable clinical safety risks associated with a potential immunological response in patients.
LC-UV-MS Method Development for Antibody Drug Conjugates Using a Non-Toxic ADC-Mimic
SigmaMab Antibody Drug Conjugate Mimic, is a non-toxic drug mimic utilized as a standard for mass spectrometry and high performance liquid chromatography.
