Key Analytical Challenges for Antibody Drug Conjugates

Currently, there are more than 75 antibody drug conjugates (ADCs) in various stages of pre-clinical and clinical development. The combination of a targeted antibody coupled with a cytotoxic small-molecule drug (via  a flexible linker) makes for a lethal and specific oncologic drug product. However, an ADC is a heterogeneous cocktail of molecules with a range…

Stripping Blots – It’s All Fun and Games Until Someone Loses Their Protein

Like all technical fields, molecular biology contains a very robust “theoretical” realm and an equally robust “practical” realm. Unfortunately, these two existences don’t seem to overlap as often as we’d like. Consider, for example, a simple Western blot. While an antibody interacting with its target on a membrane seems pretty straightforward, there are numerous other…
