: Contaminants are washed away with a dilute acid, such as trifluoroacetic acid (TFA) . c4.zip

: Removing salts, buffers, and detergents that interfere with downstream analysis. For example, researchers use them to clean samples of Trastuzumab probes or mussel biotoxins before testing. Expression, Purification and Characterization of the Human

: Enrichment of dilute samples to ensure they are within the detection range of highly sensitive instruments. Role in Mass Spectrometry binding to the C4 resin.

: Typically optimized for very small volumes (microliters).

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.
