: Best for proteins > 10 kDa and highly hydrophobic peptides.

: Contaminants are washed away with a dilute acid, such as trifluoroacetic acid (TFA) .

This technology has been instrumental in recent studies, including identifying SARS-CoV-2 protease cleavage sites and characterizing human cannabinoid receptors.

: The protein sample is aspirated through the tip, binding to the C4 resin.
